使用溶胶－凝胶法在硬质合金粉末表面涂覆了一层氧化铝陶瓷，涂层粉末经热压烧结后，制得一种新型的涂层刀具材料．这种刀具材料的耐磨性与陶瓷材料接近，并且具有较高的强度和韧性，在切削高硬度材料时表现出良好性能，具有广阔的应用前景．
Carbide powders were coated with very thin alumina films by the sol-gel process. The coated powders were then
hot-pressed as a novel cutting tool material. This material possessed relatively high hardness, which led to similar wear resistant ability with ceramics. At
the same time, its bending strength and toughness were higher than that of the ceramic cutting tool materials with similar composition. As a result, these tools show
good performance in cutting high-hardness materials. SEM and TEM photographs of coated powders and fracture surface were presented as an aid to illustrate the
strengthen mechanism.
