Conversion

Aluminum alloys are extensively used in space programs for both structural and nonstructural applications.

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.

Zinc alloy-plated steel (ZS) is widely used in various industrial applications because of its excellent resistance to corrosion^1,2.

Imagineering Finishing Technologies was recognized for its dedication to the NASA Space Launch System (SLS), Orion spacecraft, and Exploration Ground Systems programs that support the Artemis missions.

The California Air Resource Board (CARB) has promulgated Airborne Toxic Control Measures (ATCM) for several source categories that are codified in the California Code of Regulations (CCR).

An aircraft MRO required a non-hexavalent chromate as a replacement for an aluminum treatment to comply with environmental issues.

Q: I was a student in one of your recent classes on aluminum finishing, and I work for a major aerospace manufacturer, and we are having a rash of salt spray failures on our chem film test panels. Advice from numerous sources has made some improvement, but we are not totally out of the woods yet. Can you provide guidance as to what variables we should be focusing on?

The work of the Imagineering Finishing Technologies team was on full display with the launch of the Artemis 1 Space Launch System moon orbiting mission conducted by NASA.

Hubbard-Hall has expanded its product offering and customer resources by acquiring the assets of Torch Surface Technologies, a specialty chemical company based in Whitmore Lake, MI.

The applications of paints and powder coatings have become more pronounced over the years.

Chemical processing steps for chromium conversion coatings are well defined and have been used in the metal finishing industry since first developed in 1946.¹

The metal additive manufacturing industry tends to show elaborate, complex geometries—often pictured as printed or maybe even machined.

The first Wednesday of March is National Surface Finishing Day. To mark the occasion, CHEMEON is launching “The Surface Report” podcast on March 2.

Automotive isn’t the only industry that has been slow to make the formal transition from hexavalent chromium to trivalent.

When firearm enthusiast Ashley Emerson grew more dissatisfied with the night sights and the aperture hunting sights that were being offered on some of his favorite firearms, he decided to take matters into his own hand.

A customer once asked me: Why would you use the hot black oxide when the cold black is so easy?

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.
