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磨料垫的摩擦学釉化演化

目的

本研究旨在阐明不同界面压力条件下抛光液类型对固定磨料垫釉化演变的影响机制。

设计/方法论/途径

采用W3-5金刚石固定磨料垫与石英玻璃工件在摩擦磨损机械上，在3种抛光液、5种压力条件下进行了摩擦学实验。利用白光干涉仪、光学显微镜和肖氏硬度计检测固结磨料垫的表面形貌、孔隙率和硬度的变化。

发现

结果表明，固结磨料垫使用一定时间后就会出现釉化现象，且随着界面压力的增大，釉化现象更加明显。尽管上光现象不可避免，但抛光液类型对上光时间有显着影响。其机理是固定磨料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，在固定磨料垫的表面上形成光滑且高密度的硬质层，从而导致摩擦系数和表面粗糙度值的降低。对于所选抛光液类型，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为进一步了解固定磨料垫的釉化演化机制提供了一种新的研究方法。
