Nickel Silicon Carbide (CODIAC) Information
Nickel Silicon Carbide (CODIAC) is a regenerative layer of an electrolessly plated matrix, usually a nickel/phosphorus alloy, with finely divided particles uniformly dispersed in it. The particles are uniform in size and the coating contains 30% carbide by volume.
The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Reaction bonded silicon carbide has excellent wear, impact and chemical resistance. It can be formed into a variety of shapes, including cone and sleeve shapes, as well as more complex engineered pieces designed for equipment involved in mineral processing industry.
