Abstract

In this study, effect of counter gravity casting method on the adhesive wear behaviors of AlSi alloy was investigated. The counter gravity casting and gravity casting specimens were produced by pouring at 600, 640 and 690 C, with 100, 250 and 500 mmHg vacuum level in sand mould. These specimens were tested on the modified pin on disk adhesive wear tester. Adhesive wear tests were performed on the under normal loads of 20 and 60 N, and sliding speed of 1 m/s. Adhesive wear test results showed that the specimens have similar wear trend with hardness results under low load (20N), but when the load increased (60N), the specimen with highest hardness exhibited the worst adhesive wear resistance.
