Co 28.5Mo 8.5Cr 2.6Si Powder Description:
Co 28.5Mo 8.5Cr 2.6Si Powder is a specialized cobalt alloy containing molybdenum, chromium, and silicon, characterized by the formation of hard cobalt-molybdenum-silicon intermetallic Laves phases dispersed within a softer cobalt-based matrix. This composition distinguishes it from traditional cobalt-chromium-tungsten alloys, which rely on carbides for hardness. The alloy exhibits exceptional corrosion resistance, oxidation resistance, and abrasive wear resistance, coupled with high service temperature capability and good hot hardness. Tailored for HVOF spray applications, it achieves superior coating properties, including higher macrohardness, microhardness, and bond strength, with improved deposit efficiencies. Heat treatment at elevated temperatures further enhances its coating performance, making it suitable for demanding environments such as acidic and saline conditions.
