Microstructure and tribological properties of cobalt-based Stellite 6 alloy coating by electro-spark deposition

The cobalt-based Stellite 6 coating with a thickness of 0.5 mm was deposited onto 45 carbon steel by electro-spark deposition technology.Microstructure, chemical composition, phase composition, microhardness distribution and wear resistance of the coating were researched by Napkin a series of experiments.The results indicate that, the coating with
