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.
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 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.
在磨粒磨损条件下,其磨损机制主要是显微切削、颗粒脱落和脆性剥落;
In the condition of abrasive attrition, the wear loss is mainly caused by micro-cutting, particle shattered and brittle micro-peeling.
根据颗粒对表面作用的不同,磨损形貌表现为冲击、铲削、犁耕及切削等类型。
According to the difference of action parameter on surface, silt abrasion appearance registers as wedging, relieving, ploughing, and cutting, etc.
