SUBMICRON ALPHA ALUMINA HIGH TEMPERATURE BONDED ABRASIVES |
摘要 |
<p>A high temperature bonded abrasive includes alumina abrasive grits, and a vitreous bond matrix in which the alumina abrasive grits are distributed, the vitreous bond matrix having a cure temperature not less than 1000‹C. The alumina abrasive grits include polycrystalline alpha alumina having a fine crystalline microstructure characterized by an alpha alumina average domain size not greater than 500 nm, and the alumina abrasive grits further include a pinning agent that is a dispersed phase in the polycrystalline alpha alumina. ® KIPO & WIPO 2009</p> |
