The Wear Mechanisms of Diamond Impregnated Bit Matrix

Abstract

The diamond impregnated bit matrix should not only wrap the diamond up firmly; also constantly wear in the drilling process to ensure that the diamond can be made exposure constantly. The wear of diamond impregnated bit matrix is the key to affect the exposure of diamond blade.In this paper, based on the tribology, the wear mechanism of drill bits matrix is analysed from the microscopic view.Then,the relationship between matrix hardness and abrasion resistance can be obtained.
