摘　　要：介绍一种新型陶瓷涂层刀具材料及刀具，它是采用溶胶－ 凝胶法在硬质合金粉末表面涂覆一层氧化铝陶瓷，然后将涂层粉末热压烧结成形。切削试验表明，粉末涂层刀具切削高硬度材料时具有优良的切削性能。A new developed ceramic-coated tool material and cutters are introduced. This material is sintered with ceramic-coated cemented carbide powders by means of the sol-gel method. The cutting experiment shows that the coated powder cutters have an excellent performance when cutting high hardness materials.
