Conversion

CHEMEON Surface Technology and COVENTYA Group have entered into a global distribution agreement regarding the CHEMEON portfolio of MIL-SPEC QPD/QPL hex-free/Trivalent Conversion Coating technology (TCP) that provides superior adhesion and corrosion protection for aluminum and alloys.

Shay Davis, chemist and Business Development Manager for CHEMEON Surface Technology, was honored by the Society of Women Engineers at their “Night of the STEM Stars” event, receiving an Outstanding STEM Professional Award for her achievement, expertise, and work in the fields of science and technology. 

We are often asked: for functional black oxide coating, what is the thickness on a steel part? We also get asked what the thickness is on a blackened stainless steel part?

Black oxide is the conversion of a base metal material to an oxide of that base metal material.

ARCH Global Precision has acquired H. & S. Swansons’ Tool Company located in Pinellas Park, Florida, which has NADCAP-certified processes in chromate, anodize, passivation, paint and powder coating, part marking, and casting impregnation (porosity sealing).

Thanks to the U.S. Navy Environmental Sustainability Development to Integration (NESDI) program, the finishing and coating industry has a new weapon in its arsenal: enhanced trivalent chromium pretreatment, or eTCP.

Ted Ventresca is president and chief operating officer at Chemeon Surface Technology, a global leader in developing corrosion protection and surface finishing solutions to replace the known carcinogen hexavalent chrome.

Ted spent much of his career in New York City and Washington D.C., where his international media work with industry, government, media, and commercial entities now supports the future vision and growth of Chemeon.

Tens of thousands of scientists and engineers work in U.S. Department of Defense (DoD) labs inventing technologies that benefit the U.S. defense mission and the American public. This is the story of a DoD invention that became successful through technology transfer.

Extensive salt fog testing (up to 1,000 hr) is required to predict how well a coating will protect a base metal but the correlation with real-world performance is poor.  Electrochemical testing takes only a few hours and can predict how well a coating will perform in both salt fog and real-world applications.

Valence Surface Technologies, a full-service surface finishing company specializing in the commercial aerospace, defense, space and satellite industries with 12 sites across the United States, has received several approvals for its Garden Grove and Wichita operations.

For more than half a century, the finishing industry standard for conversion coating of aluminum aircraft components and surfaces was pretreatments that utilized hexavalent chromium. The result was an iridescent golden color change for ease of inspection, but the chromate was also a known carcinogen and environmental pollutant.

Automotive conversion coatings consist of layers of materials that are chemically applied to the body structures of vehicles before painting to improve corrosion protection and paint adhesion.

There is a growing interest in conversion coatings based on titanium and/or zirconium as the result of the health and environmental issues associated with legacy chromate and phosphate conversion coatings.

Chromate conversion coating is a type of conversion coating applied to passivate aluminum in order to slow corrosion.
