基于陶瓷结合剂超硬磨具优异的耐热、耐腐蚀和自锐能力,越来越多地被用于各种传统材料及难加工材料的磨削加工。但由于结合剂的脆性及低抗拉强度,陶瓷结合剂超硬磨具在高速和超高速磨削加工领域的应用还存在较大的难度。因此,针对陶瓷结合剂的增韧补强是研究和开发高速磨削用超硬材料磨具的关键因素。本文综述了国内外针对超硬磨具用的陶瓷结合剂增韧补强的研究进展,对陶瓷结合剂的微晶化增韧、第二相复合增韧和表面强化增韧的方法及机理进行了探讨。
Based on the excellent heat resistance, corrosion resistance and self-sharpening capabilities of ceramic bond superabrasives, they are increasingly used in the grinding of a wide range of traditional and difficult-to-machine materials. However, due to the brittleness and low tensile strength of the bonding agent, the application of the ceramic bond superabrasive tool in the field of high speed and ultra-high speed grinding still has great difficulty. Therefore, the toughening and strengthening of ceramic bond is the key factor to research and develop the superhard material abrasive for high speed grinding. In this paper, the research progress of toughening and strengthening of ceramic bonding agents for superhard abrasives at home and abroad is reviewed. The methods and mechanisms of ceramic toughening toughening, second phase toughening and surface toughening and toughening are reviewed Exploring.
