Investigation of Antifriction Properties of Copper Alloyed Magnesium Cast Irons

Abstract

The wear resistance of copper alloyed (0.54-1.45%) magnesium cast iron is investigated. The comparative data on wear resistance during the reciprocating motion of different friction pairs show the advantages of magnesium cast iron alloyed with 1.15% copper (wear coefficient K equals 0.35), over bronze OTsS 5-5-5 (K equals 1.57) and magnesium cast iron alloyed with 0. 5% P (K equals 0.93). Wear resistance testing with hardened rollers of magnesium cast iron specimens, alloyed with 1.15% Cu (K equals 0.37), produced results which were twice higher than those of bronze specimens AKh 9-4 (K equals 0.74).
