Abstract

Purpose

This study aims to clarify the influence mechanism of polishing solution type on the glazing evolution of fixed abrasive pad under different interfacial pressure conditions.

Design/methodology/approach

The tribological experiments were carried out on the friction and wear machinery with W3-5 diamond fixed abrasive pad and quartz glass workpiece under three polishing solution types of five pressure conditions. The changes of surface morphology, porosity and hardness of fixed abrasive pad were detected by white light interferometer, optical microscope and shore hardness tester.

Findings

The results showed that the glazed phenomenon of fixed abrasive pad is occurred after a certain time, which is more obvious with the increasing of interfacial pressures. The polishing solution type has a significant effect on the glazing time, although the glazed phenomenon is inevitable. The mechanism of it is that the micro-convex peaks on the surface of the fixed abrasive pad are easily wear, and the pores are blocked by the accumulation of waste debris generated during the experiment process. Thus, a smooth and high-density hard layer is formed on the surface of the fixed abrasive pad which induces the decreasing of the friction coefficient and surface roughness value. For selected polishing solution types, the wear rate of micro-convex peaks is different due to the corrosion action difference with polishing pad surface.

Originality/value

The main contribution of this work is to provide a new investigating method for further understanding the glazing evolution mechanism of fixed abrasive pad.

不同抛光液条件下固定研磨垫的摩擦学上釉演变

设计/方法/途径在三种抛光液、五种压力条件下，对 W3-5 金刚石固定研磨垫和石英玻璃工件的摩擦磨损机械进行了摩擦学实验。结果表明，固定磨片在使用一定时间后会出现釉化现象，随着界面压力的增加，釉化现象更加明显。抛光液类型对上釉时间有显著影响，但上釉现象不可避免。其机理是固定研磨垫表面的微凸峰容易磨损，实验过程中产生的废屑堆积堵塞了孔隙。因此，固定研磨垫表面形成了光滑的高密度硬层，从而导致摩擦系数和表面粗糙度值降低。对于选定的抛光液类型，由于与抛光垫表面的腐蚀作用不同，微凸峰的磨损率也不同。原创性/价值这项工作的主要贡献是提供了一种新的研究方法，有助于进一步了解固定研磨垫的釉面演变机理。同行评议本文的同行评议记录可在以下网址查阅：https://publons.com/publon/10.1108/ILT-08-2023-0257/。
