Oilfield PDC drill bits are widely used drilling tools for oil wells, which enhance cutting performance and wear resistance through the use of multi‑layer sintered diamond. However, under high loads and severe wear conditions, the sintered diamond layer of PDC bits is susceptible to damage. To extend service life and improve operational efficiency, surfacing technology is widely applied to oilfield PDC bits.
Surfacing is a technology that uses a high‑energy heat source to melt and bond metallic materials. It is often used for repair and improvement of surface properties of products. For PDC bits, surfacing can restore the worn and damaged diamond layer, as well as enhance its wear resistance and corrosion resistance.
