Description
Technical field
The present invention is about ground finish abrasive material, particularly a kind of ceramic corundum abrasive material that contains complex phase additive (SG abrasive material).
Background technology
The appearance of abrasive material and use are the quantum jumps on history of human civilization, and along with industry and scientific and technical development, the use range of abrasive material is increasingly extensive, also more and more higher to the requirement of its performance.Ceramic corundum abrasive material (being SG abrasive material) is since coming out, due to series of advantages such as its self-sharpening is good, good toughness, durability height, be subject to extensive concern both domestic and external, it both can be applied to a series of difficult-to-grind materials aspects such as toughness stainless steel, refractory alloy, also can be for precision and the high efficient grinding of general material, therefore at many industrial circles, there is very large application potential, become the emphasis of research in world wide.At present, high-grade ceramic corundum abrasive material and emery wheel dependence on import still on domestic market, and expensive, therefore, domestic many scholars are actively devoted to suitability for industrialized production and the application of this abrasive material.
Ceramic corundum abrasive material (being SG abrasive material) is to adopt wet chemistry method preparation, need be through high temperature sintering crystal conversion, densification and reach abrasive material level hardness, because the sintering Diffusion Activation Energy of pure alumina is higher, under low temperature, be difficult to sintering, too high temperature easily causes again abnormal grain growth, destroy its microstructural homogeneity, and then damage a series of mechanical propertys such as sintered article intensity, toughness.Therefore, how to reduce the sintering temperature of corundum, optimize its microtexture, be one of focus of ceramic corundum abrasive material preparation research all the time.Investigator finds by adding a small amount of sintering aid or adopting advanced sintering method etc. all can obtain desirable abrasive material at relatively low temperature, and wherein, the introducing of a small amount of additive, on the basis reducing production costs, helps that to burn effect more remarkable.Coble reported first in 1961 introducing of the MgO promoter action to alumina sintering, caused thus the research of various additives to corundum abrasive performance.TiO
