- Abstract
Aiming at clarifying the effective mechanism of ethylenediamine additive on the glazed phenomenon of fixed abrasive pad (FAP) under deionized water polishing slurry condition, tribological experiments were carried out with W3-5 diamond hydrophilic FAP and silica glass workpiece. The influence of ethylenediamine on the FAP surface glazed phenomenon was studied by analyzing the friction coefficient, FAP surface morphology and hardness, workpiece surface morphology, and material removal rate (MRR) after the experiments. The results show that the ethylenediamine can significantly prolong the FAP service life. With the increase of ethylenediamine concentration, the FAP glazed time first increased and then decreased, and the biggest value was observed in the 4% ethylenediamine concentration. Besides, the concentration increasing of the ethylenediamine promotes the softening layer formation on the workpiece surface, and the bigger surface roughness value of it is obtained. Detailed analysis shows that the FAP surface hardness is reduced due to the reaction between the ethylenediamine and the copper exposed on its surface. Thus, the swelling layer of FAP is rapidly softened and removed, and the fresh abrasives are exposed at this case. So, a high material removal ability of FAP is obtained for a longer time, and the surface glazed phenomenon is restrained.
