What is Wear Analysis of WC Drill Bit Buttons about?

This document summarizes the critical investigation of wear behavior of tungsten carbide (WC) drill bit buttons. It discusses how WC drill buttons are subjected to high abrasion and erosion from rock and drilling fluids during mining and petroleum drilling. The document analyzes the wear mechanisms of WC drill buttons through scanning electron microscopy of buttons used in various rock types. It identifies the main types of failure mechanisms for cemented carbide buttons as partial rock cover, microcracking
