Abstract

Understanding how the wear environment and the history of the wear surfaces affect wear and wear rates is extremely important in mineral processing and mining applications. Through this, the lifetime expectations of wear parts can be estimated more precisely in wear environments with constantly changing abrasive media. Certain mineral combinations can increase wear rates extensively compared to some others. The economical effects of unnecessary down-times are significant. In this study, the effects of embedded quartz layer on wear rates were investigated. Hard metals, metal matrix composites, and several types of steels were studied to find differences in their wear behavior. Running-in of the specimens was performed using quartz or granite abrasives to create surfaces with and without embedded quartz. Only granite was used as an abrasive in the actual wear tests. For low-hardness materials (
