3D Printing Alloy CoCrW Powder

Overview of 3D Printing Alloy CoCrW Powder

Cobalt-chromium-tungsten alloy (CoCrW) is one of the Stellite alloys. Stellite alloy is a hard alloy that can withstand various types of wear, corrosion and high-temperature oxidation. It is commonly referred to as a cobalt-based alloy. CoCrW can resist all kinds of wear, corrosion and oxidation at high temperatures. According to the composition of the alloy, it can be made into welding wire, used for hard surface surfacing, thermal spraying, spray welding powder. Stellite was originally a binary cobalt-chromium alloy and later developed into a ternary composition of cobalt-chromium-tungsten. Cobalt-chromium-tungsten alloy is a kind of alloy with cobalt as the main component, containing a considerable amount of chromium, tungsten and a small amount of nickel, molybdenum, silicon, carbon, niobium, tantalum and other alloying elements, and occasionally also containing iron. Unlike other high-temperature alloys, cobalt-chromium-tungsten alloys are not strengthened by an ordered precipitation phase firmly bonded to the matrix but are composed of austenite fcc matrix that has been solid-solution strengthened and a small number of carbides distributed in the matrix. However, the casting of cobalt-chromium-tungsten superalloys relies to a large extent on carbide strengthening
