激光表面造型在改变材料摩擦、磨损性能方面具有独特的优点,本文设计了三种不同的微造型图案(圆、菱形和网格),在相同激光参数条件下对球墨铸铁材料表面进行微观造型,分别在万能摩擦磨损试验机上进行有油润滑摩擦磨损试验,并用数字天平称量摩擦前后质量变化,进行磨损量和摩擦系数的比较。研究结果表明激光造型表面有利于摩擦副减磨降摩;网格造型优于常见的圆形和菱形造型,这在一定程度上证明了网格具有良好的储屑能力和多路润滑油传送能力,更可达到减磨降摩的作用。
Laser surface modeling has unique advantages in changing the friction and wear properties of materials. In this paper, three different micro-modeling patterns (circles, diamonds and grids) are designed. The surface of the ductile iron material is micro-sculpted under the same laser parameters, Respectively, in a universal friction and wear testing machine oil lubrication friction and wear tests, and with a digital balance before and after the friction mass change, wear and friction coefficient comparison. The results show that the laser surface is beneficial to friction reduction and friction reduction; the mesh shape is better than the common circular and rhombus shapes, which proves to some extent that the mesh has good chip-holding ability and multi-lubricant delivery ability , But also to achieve the role of anti-friction.
