    Abstract
    Ethylenediamine with two −NH 2 functional groups was used as a critical complexing agent in chemical mechanical polishing slurries for a high carbon chromium GCr15 bearing steel. The polishing performance and corresponding mechanism of −NH 2 functional groups were thoroughly investigated as a function of pH. It is revealed that, when polished with ethylenediamine and H 2 O 2 -based slurries, the material removal rate and surface roughness R a of GCr15 steel gradually decrease as pH increases. Compared with acidic pH of 4.0, at alkaline pH of 10.0, the surface film of GCr15 steel...
