【摘要】：基于工程陶瓷二維預(yù)壓應(yīng)力磨削方法,進(jìn)行了氧化鋁陶瓷在不同二維預(yù)壓應(yīng)力條件下的磨削試驗(yàn),探究氧化鋁陶瓷材料的去除機(jī)理和加工損傷。結(jié)果表明,相同的磨削深度下,隨著二維預(yù)壓應(yīng)力值增加,磨削力增大,陶瓷工件磨削表面質(zhì)量提高,磨削表面的粗糙度降低,亞表面損傷層厚度減小。預(yù)壓應(yīng)力使裂紋擴(kuò)展所需能量增大,從而減少裂紋,提高磨削表面質(zhì)量。
[Abstract]:Based on the two dimensional precompression stress grinding method of engineering ceramics, the grinding experiments of alumina ceramics under different two dimensional precompression stress conditions were carried out to explore the removal mechanism and processing damage of alumina ceramic materials. The results show that at the same grinding depth, the grinding force increases with the increase of 2-D preloading stress, the grinding surface quality of ceramic workpiece is improved, the roughness of grinding surface is reduced, and the thickness of subsurface damage layer is reduced. Preloading stress increases the energy required for crack growth, thereby reducing cracks and improving grinding surface quality.
