Description
Technical field
The present invention is about the ground finish abrasive material, particularly a kind of ceramic corundum abrasive (SG abrasive material) that contains the complex phase additive.
Background technology
The appearance of abrasive material and use are the quantum jumps on the human civilization history, and along with industry and science and technology development, the use range of abrasive material is increasingly extensive, and is also increasingly high to its performance demands.Pottery corundum abrasive (being the SG abrasive material) is since coming out; Because series of advantages such as its self-sharpening is good, good toughness, durability height; Received 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 used for the precision and the high efficient grinding of general material; Therefore at many industrial circles very big application potential is arranged, become the emphasis of research in the world wide.At present, high-grade ceramic corundum abrasive and emery wheel dependence on import still on the home market, and cost an arm and a leg, therefore, domestic many scholars actively are devoted to the suitability for industrialized production and the application of this abrasive material.
Pottery corundum abrasive (being the SG abrasive material) is to adopt the wet chemistry method preparation; Need to reach abrasive material level hardness through high temperature sintering crystal conversion, densification; Because the sintering of pure alumina diffusion activation energy is higher, is difficult to sintering under the low temperature, too high temperature is prone to again cause that crystal grain grows up unusually; 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 preparation research all the time.The investigator finds that wherein, the introducing of little additive on the basis that reduces production costs, helps the burning effect more remarkable through adding a small amount of sintering aid or adopting advanced sintering method etc. all can under relatively low temperature, obtain the ideal abrasive material.Coble reported first in 1961 introducing of MgO to the promoter action of alumina sintering, caused of the research of various additives thus to the corundum abrasive performance.TiO
