Studying properties and structure of antifriction cast iron additionally alloyed with titanium

Abstract

This article presents data on the study of the properties and structure of antifriction cast iron additionally alloyed with titanium. On the basis of experimental data favorable effect of titanium microalloying in an amount of 0,25 % on the performance properties of antifriction gray cast iron AChS-2 is shown: sliding factor increases almost 1,5 times, shape, and size of craters after shock-cycling impact are improved. This improvement in properties suggests an increase in structural strength and service life of parts made of the experimental alloy. The alloy was smelted in an industrial furnace.
