摘要： An abrasive article can include an abrasive component including a body. The body can include a bond matrix and abrasive particles contained in the bond matrix. In an embodiment, the body can include an interconnected phase extending through at least a portion of the bond matrix. The body can include a discontinuous phase including a plurality of discrete members. At least one of the discrete member can include a macroscopic pore. In another embodiment, the body can include a porosity of at least 15 vol % for a total volume of the body.

摘要： An abrasive particle can include a coating overlying at least a portion of a core. In an embodiment, the coating can include a first portion overlying at least a portion of the core and a second portion overlying at least a portion of the core, wherein the first portion can include a ceramic material and the second portion can include a silane or a silane reaction product. In a particular embodiment, the first portion can consist essentially of silica. In another particular embodiment, the first portion can include a surface roughness of not greater than 5 nm and a crystalline content of not greater than 60%.
