![]() ![]() SermeTel™ 5380 CF coating offers advanced corrosion protection with a smoother surface finish that improves efficiency for compressor components. SermeTel™ 6F-1 CF coating provides corrosion protection in high-temperature conditions and meets stringent OEM gas turbine specifications. Suitable applications include bearing supports, cases, shafts, compressor blades and vanes. SermeTel™ 2F-1 CF coating is designed to provide protection from severely corrosive conditions. Looking for unsurpassed protection against aqueous corrosion and heat scaling, as well as erosion and abrasion resistance? Our SermeTel™ CF chrome-free coatings systems offers that and more. With a relatively low diffusion temperature, the post-coating heat treatment process is eliminated, which allows components to be refurbished without risking damage to brazed joints. ![]() Compatible with austenitic stainless steel and nickel- and cobalt-based superalloys, the diffusion SermaLoy J CF treatment can be tailored to each alloy and application. ![]() Our SermaLoy® J CF chrome-free diffusion coating offers protection against hot corrosion and oxidation attack in the combustor and turbine sections. The coating applications and associated coatings below are developed to effectively replace chrome and cadmium plating and ultimately improve the performance of your most critical components. That’s why we’ll work directly with you to understand your unique challenge and find the solution that gets you more performance from your parts and equipment. Rather than forcing a standard solution, we’re interested in making more possible. For us, each problem is a unique event, requiring a unique answer. Below are some of the REACH-compliant options available as replacements for hexavalent chrome and cadmium coatings and platings. Whatever the problem, we have a coating solution for it. While chrome (and cadmium) platings are inexpensive and easy to apply, their environmental and health risks outweigh the benefits. At Praxair Surface Technologies, our broad portfolio of coating materials and application technologies ensures you get equivalent or better performance compared to hexavalent chrome and cadmium containing platings without associated environmental regulations and employee hazards. It is included in the list of chemicals that have been identified as substances of very high concern, the use of which is restricted and can only be used under authorization in Europe. Wastes generated also must be treated and disposed as hazardous waste. The hard chromium plating process uses hexavalent chromium based raw materials in plating tanks and emits a mist into the air that must be ducted away and removed by scrubbers. It is the most toxic form of Chromium and is a known carcinogen. Hexavalent Chromium containing material is under REACH requirement and authorization list in the EU and is heavily regulated by the EPA in the United States. This means increased protective measures - and costs - now follow the use of the material. The use of hard chrome plating is heavily regulated by the Environmental Protection Agency in the United States because it is a known carcinogenic process. However, modern metallurgical science has provided thermal spray coating options with many similar wear and resistance qualities. From corrosion protection to resistance to sliding wear or abrasion, hard chrome plating is a favored option for appearance and strength. It is used in both industrial and decorative applications due to its abrasion resistance and other unique properties. Hard chrome plating provides a shiny, hard and anti-corrosive surface on existing metals. Hard chrome plating roared onto the scene in the 1920s and was primarily used on motorcycles and cars to combat corrosion and wear. ![]()
