Green Coating Technology

Green Coating Technology

Our Newest Fine to Amorphous grain and Fine to Nano particle technology is an Environmentally Friendly Coating Technology. This green technology is not only safer than Hard-Chrome, it meets or exceeds Hard Chrome’s Performance, while being environmentally friendly:

TM-Xcalibur is a hard coating that can have low coefficient of friction, outperform chrome in wear applications with two to four times, and three to ten times the corrosion resistance of chrome. This coating has some leveling properties, which helps maintain surface Ra. TM-Xcalibur is mainly used in high wear, antigalling, release, or corrosive type applications. TM-Xcalibur can be applied to all ferrous metal & most nonferrous metals. As coated the hardness is 520 to 750 Vickers and after heat-treatment of 400 F for six hours hardness increases to 900 to 1100 Vickers. TM-Xcalibur in the pin-on-disc wear testing has outperformed Hard Chrome results by 2 to 4 times in wear resistance. TM-Xcalibur Deposit and Process is CHROME FREE. The coating is bright, scratch resistant, and is environmentally friendly. See Customer Study Article


Diamonize has become a solution to many wear, abrasion, corrosion, and erosion problems. It is a perfectly uniform coating process, which is a low temperature alternative to standard thermal spray processes. Diamonize can increase the life of moving, rotating, and static equipment, which sees high wear in critical applications, including food grade equipment. Diamonize can be applied to all ferrous and non-ferrous alloys & does not have line of sight limitations. Diamonize has increased equipment life from 3 to 10 times in some applications. Diamonize can be removed and then recoated later. Most importantly, this technology is an environmentally friendly alternative to other processes such as electroplating, flame spray, HVOF, hardening, and chrome plating. This uniform coating eliminates the need for post machining requirements in most applications. Coating thickness can vary based on parts and applications. Most common thicknesses are .002 to .015  with +/- tolerances of .0005 or .001.

Techmetals Pushes Green Technology that has fine micro/nano membranes and are an EPA recognized technology.

The fine membrane Emission Elimination Device or “EED” cover technology has been purchased by Palm International. Palm has the resources and distribution network to better supply this technology in today’s global market. We feel it is important to share our technology to help assure the success of our plating industry.

Techmetals supports Green technology and supports the manufacturing efforts in Canada and the USA by releasing Chrome Plating & the Fine Membrane Emission Elimination Device (EED) Technology.

Both the US EPA and the Canadian EPA recognize the Fine Membrane EED cover Technology as an acceptable solution to control emissions as the “best available technology”.

Articles Supporting Fine Membrane EED Technology:

Facilities Using EED Technology:

The Naval Air Systems Command Depot (NADEP) facility located on the Naval Air Station (NAS) North Island, San Diego, CA currently has five (5) hard chrome plating tanks in operation. The facility typically plates 3-5 million amp-hours per year and is identified as a Small Hard Chromium Electroplating Facility by the San Diego Air Pollution Control District. This presentation addresses the implementation of encapsulating tank covers, hereafter referred to as the Chrome Plating Emission Elimination Device (EED), on the NADEP’s hard chrome plating process tanks, as an alternate control devise used to eliminate Cr+6 emissions to the outside environment, reduce operating costs, and provide enhanced operator safety and exposure in the chrome plating facility. See Link:

Other Supporting Information:

The Fine Membrane Emission Elimination Device (EED), formerly known as the Merlin Cover, is a patented process that encloses a process tank while chrome plating is being conducted. The EED incorporates strategically located and appropriately sized membrane(s), which allow for free passage of gases while effectively blocking escape of water vapor and chemical mist. The Fine Membrane EED is a stand-alone, self-contained unit requiring no supplementary equipment (e.g. blower) or exhaust to outside the facility.

During Hard Chromium electroplating, a number of by–products are generated, namely hydrogen gas, oxygen gas, water vapor and chromic acid mist. The hydrogen and oxygen gases are generated as a by–product of the electrolytic reaction during chromium plating. The Chromic Acid Mist is generated because of the bursting action of hydrogen and oxygen gases at the surface of the plating solution. In conventional ventilation systems, these mist particles are carried away by blowing air across the tank. In addition, since the tank is open to the atmosphere, stray air currents add to the mobility of these particles. In the absence of such air movement, these mist particles will rise and then fall back into the solution because of gravity.

image001The Emission Elimination Device

For a chromium electroplating tank equipped with EED gases generated during the chromium plating operation escape through the patented membrane on the EED Water Vapor condenses on the inside walls and top of the enclosure. The condensate runs back into the plating solution. Chromium Mist, being heaviest of all by–products and because of the absence of any significant air movement, rises to a limited height and then also falls back into the plating solution. The denser air, caused by the presence of water vapor mist, further reduces upward mobility of the chromium mist particles. In addition, the water vapor mist and droplets of condensed water provide scrubbing of the air inside the EED. In setups where chromium mist extends to the height of buss bars, the water droplets keep chromic acid off the buss bars, extending their life and those of other components of the plating system.

Design and Installation

An adapter is affixed to the top of the plating tank walls with appropriately placed and properly sealed openings for buss bar, plumbing, and electrical conduits, etc. A hinged hood, with counter weights or other mechanical means of opening, is then placed on top of the adapter. A deformable sealing gasket material (compatible with process chemicals) is placed between the tank wall and adapter as well as between the hood and the adapter. An evacuation process is also incorporated into the system as a means of removing any mists or fumes that remain under the hood after the plating process is completed. Gases from the evacuation are exhausted through a filter.

The EED Plating Process

Parts to be plated are placed on the buss bars. The contacts must be cleaned and secured to avoid any sparking during plating. After the cover is closed and secured, the rectifier is turned on and the interlocks automatically engage to secure the access door. Interlocks ensure that the door is not opened while plating is being conducted in the tank. When the rectifier is turned off, the evacuation unit automatically turns on and the evacuation unit must be run for its specified period (approximately 1- 5 minutes, per manufacturer’s recommendation). The process is automatic.

EED Advantages

There are many advantages to using the fine membrane EED, not least of which is safety. Tanks are turned off during start–up, preventing arcing and reducing the chance of hydrogen explosion. In the unlikely event of an explosion, the EED shields the operator from the splashing solution. The unit’s design is simple ?there are no exhaust hoods, duct work or fume scrubbers or fans, reducing the number of working parts.

Additionally, an effluent control for treating fume scrubber solutions is not required, which means less press/dry time. Because the exhaust hoods, ducting and scrubber equipment are eliminated, more floor space is available for additional equipment and additional costs for materials and labor to maintain scrubber systems are eliminated. Noise reduction, significant cost savings, and water and energy savings round out the many advantages to using the EED in chrome plating applications.

The Emission Elimination Device promises to save time, energy and costs for chrome plating applications. Information for this article was supplied by Responsible Alternatives, Inc., 4027 Colonel Glenn Hwy, Dayton, OH 45431-1672

Wastewater treatment equipment that is designed correctly, operated responsibly, and by improving methods by working with your Local, State, and Federal Agencies can prevent fines from the Environmental Protection Agency (EPA), OSHA, or other governmental agencies. The key is working together with Local, State, and Federal Environmental and Governmental agencies to protect the environment and the community. This is a goal everyone has in common.

Another approach is to work with Local, State, and Federal agencies to reduce effluent and wastewater containing heavy metals. A method to reduce wastewater can be done by making as many processes as close too close-looped as possible. Completely closed looped is almost impossible with current technology.

Techmetals started reducing wastewater in areas and becoming more close looped by developing the fine membrane Emission Elimination Device Technology. This has greatly reduced wastewater in some areas and has also reduced and eliminated the need for scrubbers and ventilation that can release emission and waste into the environment.

Companies, manufacturing, metals finishing shops, and plating companies, just like most industries can have environmental issues that lead to fines from the EPA, OSHA, or other governmental type agencies. To keep our employees safe, other companies employee’s safe, and help protect our environment Techmetals developed the Fine Membrane Emission Elimination Device (EED) technology.
