摘要: A hardfacing is provided to protect surfaces of drill bits and other downhole tools. The may include tungsten carbide particles or pellets formed with an optimum weight percentage binding material dispersed within bonded a matrix deposit. be by sintering appropriate techniques. have generally spherical shapes, partially shapes non-spherical shapes.
