摘要： In order to improve the adhesion and wearing properties of a composite body with a hard metal, steel or cermet substrate or a substrate body of a nickel or cobalt-based alloy and one or more surface layers, of which the outer one preferably consists of alpha aluminium oxide, it is proposed that this outer layer has a fine-crystalline alpha modification, the diffraction lines of which measured through the half-widths with X-ray beams have half-widths which are at least three times as great as those of a powdered alpha aluminium oxide compact body. In order to produce this alpha aluminium oxide layer, it is proposed to perform a plasma-activated CVD process at temperatures of 400 to 750 DEG C. The composite body is highly suitable as a cutting material, a high-temperature material or a hard-wearing material for friction components.
摘要翻译：为了提高具有硬金属，钢或金属陶瓷基板或镍或钴基合金的基体和一个或多个表面层的复合体的粘合性和磨损性，其中外表面优选由α 氧化铝，建议该外层具有细晶α改性，通过X射线束的半宽度测量的衍射线具有至少三倍于粉状α氧化铝致密体。为了生产这种α氧化铝层，建议在400至750℃的温度下进行等离子体激活的CVD工艺。复合体非常适合作为切削材料，高温材料或硬质合金，耐磨材料用于摩擦部件。

摘要： The invention relates to a cutting insert (10) for stock-removing machining having on its faces (102) a plurality of longitudinal ribs (171 to 173), the longitudinal axes of which are substantially perpendicular to the cutting edge (101) or are at an acute angle to the plane normal to the cutting edge and of which one group consisting of every other longitudinal rib is arranged mutually parallel. The longitudinal ribs (171 to 173) preferably have at least one recess (18) reaching the face (102).
