Abstract

New wear-resistant special cast iron CHMN-35M was produced to be used for parts which are operated under the conditions of intense friction loads. Based on obtained results, technical requirements by chemical compounds and mechanical properties were determined. Wear resistant properties of experimental material in friction couples with a different type of steel were investigated. Experimental samples were tested by static and impact bending to evaluate strength and crack resistance of the material. Fractography investigations of samples after mechanical test were carried out. Influence of nickel and molybdenum on structure and mechanical properties of special cast iron CHMN-35M are presented in this work.

Keywords: Wear resistant cast iron, cast iron CHMN-35M, tribological properties, nickel and molybdenum influence, martensite in grey cast iron
