The complex layers are compacted and well-proportioned,the shear strength of which is 625 MPa and wear value is reduced by 10%～70%. The complex layers prolong the working life of steel tooth roller cone bit.
研究表明:金刚石经过金属化处理后表面具有一定的金属性和浸润性,通过一定堆焊工艺在钢齿牙轮钻头齿面形成了组织致密均匀、硬质点与基体熔合良好的强化层,其抗剪强度达到了625MPa,磨损量减少了10%～70%,延长了钻头的使用寿命。
