Light metal cylinder for internal combustion engine piston - has electrolytically deposited wear resistant coating of nickel@ or iron@ dispersed with boron carbide
摘要
Light metal cylinder of a piston engine has a wear-resistant coating of a Ni or Fe dispersion coating contg. tetra-B carbide. The coating is deposited electrolytically from a bath contg. the carbide. In use, the coating forms NiB2C at 350 deg.C and Ni3B from 450 deg.C or FeB and Fe2B. ADVANTAGE - Maximum resistance to wear.
