在小颗粒松散磨料的低磨损区,磨损机理主要是微观切削磨损机理,表面有明显的犁沟或者印痕。
In the low wearing area of the loose abrasive of tiny particle, wear mechanism is mainly the micro-cuts wearing mechanism, and the surface has obvious furrow and indentation.
涂层剥落后,切削区产生的瞬时热量聚集使基体粘结相软化,从而导致硬质相颗粒脱落和基体的剧烈磨损。
After the coating broke off, the instantaneous heat builds up and softens the substrate's bonding phase, which results in breaking off of hard phase particles and sharp wear of substrate.
复合涂层的磨损机制主要为硬质颗粒的脆性脱落,同时伴随着轻微的显微切削。
The wear mechanism of the coating attributes to the brittleness shedding of the hard phase particles going with a slight micro-cutting.
