METHOD FOR APPLYING HARDFACING TO A MATRIX SUBSTRATE OF A DRILL BIT |
摘要 |
A method for hardfacing a drill bit includes applying a hardfacing material to a matrix metal forming the substrate of the drill bit. The hardfacing material is applied using a plasma arc welding process. A metallurgical bond is formed between the matrix metal and the hardfacing material. The matrix metal may include tungsten carbide and a braze filler metal. |
