PROBLEM TO BE SOLVED: To provide abrasive products in which: the material removal rate (MRR) and cumulative material retention (CMR) are significantly increased; "surface finish" or "Ra" of a work piece also is significantly improved; and the usable life can be significantly extended.SOLUTION: A surface-modified abrasive grain 16 includes an abrasive grain as a substrate, and a film on the abrasive grain that includes a relatively hydrophilic silane component and a relatively hydrophobic silane component. The film can be a single film layer or multiple film layers, where a film layer most proximal to the abrasive grain has a predominately hydrophilic silane component while a film layer more distal to the abrasive grain includes predominately a relatively hydrophobic silane component. Coated abrasive products 10 and bonded abrasive products include the surface-modified abrasive grains. |
