Wear-resistant cast iron for sliding surfaces

A wear-resistant and self-lubricatory cast iron for use with a compositely electroplated layer of a high wear resistance in sliding contact relation. The cast iron contains, in addition to carbon, silicon, manganese and chromium, cobalt for solid solubilization with the iron matrix and provision of...

Zusammenfassung:	A wear-resistant and self-lubricatory cast iron for use with a compositely electroplated layer of a high wear resistance in sliding contact relation. The cast iron contains, in addition to carbon, silicon, manganese and chromium, cobalt for solid solubilization with the iron matrix and provision of high heat resistance, molybdenum and niobium for formation of such specific granular carbides as composite carbides of molybdenum and carbides of niobium and providing a high wear resistance, nickel for acceleration of graphitization and even distribution of fine and dense graphite in the iron matrix, and boron for aid of such acceleration in cooperation with the molybdenum thus providing high lubricity, the remainder being iron and impurities.
