CO5777 Co 28.5Mo 17.5Cr 3.4Si Powder

Co 28.5Mo 17.5Cr 3.4Si Powder Description:

Co 28.5Mo 17.5Cr 3.4Si Powder is a high-performance Cobalt alloy containing Molybdenum, Chromium, and Silicon. It is characterised by the formation of hard intermetallic Laves phases based on cobalt-molybdenum-silicon, which are dispersed in a softer cobalt matrix, differentiating it from typical cobalt-chromium-tungsten alloys that derive their hardness from carbides. This unique microstructure provides the alloy with exceptional corrosion and oxidation resistance, as well as excellent wear resistance at high operating temperatures and good hot hardness. The coatings exhibit a low friction coefficient, making them particularly suitable for applications where minimal or no lubrication is present. The HVOF coatings are designed for atmospheric plasma spraying or HVOF spraying and achieve higher macrohardness, microhardness, bond strength, and deposition efficiency. The coating properties are significantly improved by subsequent high-temperature heat treatments that enhance the volume fraction of Laves phases. These coatings provide robust corrosion resistance in most acidic and saline environments.
