Self-lubricating ceramic cutting tool material added with h-BN@Al2O3 coated solid lubricant and preparation method of self-lubricating ceramic cutting tool material
The invention relates to a self-lubricating ceramic cutting tool material added with an h-BN@Al2O3 coated solid lubricant and a preparation method of the self-lubricating ceramic cutting tool material, and belongs to the field of ceramic cutting tool materials. The self-lubricating ceramic cutting tool material is prepared from alpha-phase aluminum oxide as a matrix, titanium carbide as a reinforcing phase, magnesium oxide as a sintering aid and h-BN@Al2O3 coated powder as a solid lubricant through wet ball-milling mixing and vacuum hot-pressing sintering. The h-BN@Al2O3 coated powder is prepared through a non-uniform nucleation method. The self-lubricating ceramic cutting tool material disclosed by the invention is relatively good in sintering compactness, the coated powder is free from agglomeration, and the self-lubricating ceramic cutting tool material has good bonding degree with an Al2O3/TiC matrix, so that the mechanical property of the ceramic material is enhanced.
本发明涉及一种添加h‑BN@AlO包覆型固体润滑剂的自润滑陶瓷刀具材料及其制备方法，属于陶瓷刀具材料领域。该自润滑陶瓷刀具材料是以α相氧化铝作为基体，以碳化钛作为增强相，以氧化镁为烧结助剂，以h‑BN@AlO包覆粉体为固体润滑剂，经过湿法球磨混料和真空热压烧结制备而成。h‑BN@AlO3包覆粉体通过非均匀成核法制备。本发明的自润滑陶瓷刀具材料的烧结致密性较好，包覆粉体没有出现团聚现象，且于AlO/TiC基体具有良好的结合度，增强了陶瓷材料的力学性能。
