| Abstract: | Microstructures of molten vitrified bond have an important effect on the behaviour of the corundum grinding wheel.The authors studied the microstructures of the molten vitrified bond corundum grinding wheel,as well as the impurities in the abrasive grains.The reaction characteristics between the abrasive grains and the bond was revealed by electronic probe micro area analysis(EPMA).The results showed that the molten bond was in a glassy state,the bond-bridge and the abrasive grains were bonded well.The impu... |
