叶轮表面各种抛光方法的去除机理研究及磨料的研制

从力学去除机理对振动抛光和磨料流抛光进行了分析研究,提出了旋转磨粒流抛光,从而增加了运动行程长度,提高了材料去除率;同时,能使工件表面更加平整,也会改善表面的应力状态.分析了如何配制最合适的磨料流加工研磨磨料,通过几种不同配料的对比实验,最后提出了一种润滑油、橡胶和磨粒的混合模型,可以兼顾高强度、高扯裂性、氧化安定性和润滑性.

Study of Removal Mechanism of Polishing Method of Wheel Surface and Development of Abrasive

This article makes an analytic study of vibration polishing and abrasive flow polishing, from the perspective of mechanical re- moval mechanism, puts forward the rotating abrasive flow polishing, which can increase the motion stroke length and improve the material removal rate,at the same time,it can make the surface more smooth and improve the surface stress state. It analyzes how to produce the most suitable abrasive flow abrasives, through the contrast experiment of several different ingredients. In the end it puts forward a kind of lubricating oil, rubber and abrasive mixture model, which can satisfy the high strength, high tear resistance, oxidation stability and lubricity.
