摘要
通过观察切削花岗岩过程中聚晶金刚石复合片(PDC)刀具的磨损过程和磨损形貌,研究PDC刀具的磨损规律。研究结果表明:切削花岗岩时,受切削力及其冲击的作用,PDC刀具产生近乎平行岩石表面的磨损形式,磨损机理为机械作用引起聚晶金刚石层微观裂纹产生并扩展而导致的金刚石颗粒的微观破碎。
The wear properties of polycrystalline diamond compact (PDC) cutter used for cutting granite are investigated by observing the wear performance and wear surface of the same. The study shows that in granite cutting processes, PDC cutter is worn by micro chipping in diamond grains due to mechanical action, and the wear surface is almost parallel to the rock surface.
