摘要： Disclosed are an element comprising a hard metal substrate (10) and a diamond layer (30), and a method for coating a hard metal substrate (10). Said hard metal substrate is provided with hard material particles (20) and surrounding binder material (22). The hard material particles (20) are surrounded by binding material (22) in a first area (24) comprising intact hard metal. The transition region of the first area (24) encompasses a deep profile having recesses (18) and elevations (16). The diamond layer (30) is braced with the substrate material (10) with the aid of said deep profile, portions of the diamond layer (30) being disposed deeper within the substrate (10) than elevations (16) of the first area (24). Said structure is obtained by means of a pretreatment process in which a hard metal substrate (10) is first subjected to selective etching in order to remove the binding material (22). A porous zone having a deep profile is formed. The hard material particles located within the porous zone (12) are removed by means of microbeams or a second, WC-selective etching step. A cobalt concentration on the surface is finally removed in a Co-selective etching step, and the substrate (10) is coated with a diamond layer by means of CVD.

摘要： A description is given of a coated body and a method for producing and coating a body. The body has a substrate of a hard metal or cermet, comprising hard material particles (1) and binder material (2) and an adhering diamond layer (4) provided on top. At least some of the hard material particles (1) on the surface of the substrate and under the diamond layer (4) have transcrystalline depressions in the form of holes. The substrate may consist of hard metal, preferably consisting of WC and Co. A CVD diamond layer may be applied to the functional surfaces. In the case of at least one of the diamond-coated functional surfaces, the cobalt content of the surface, specified in % by weight, in relation to the WC, measured by means of energy-dispersive X-ray fluorescence, is only reduced by a maximum of 50% in comparison with the untreated substrate. In the method according to the invention, hard material particles on the surface of the substrate are subjected to transcrystalline corrosion by chemical etching in such a way that depressions are created in the form of pits or holes.
摘要翻译：给出了涂覆体及其制造和涂覆方法的描述。主体具有硬质金属或金属陶瓷的基底，其包括硬质材料颗粒（1）和粘合剂材料（2）以及设置在顶部的附着金刚石层（4）。衬底表面上和金刚石层（4）下方的至少一些硬质材料颗粒（1）具有孔形状的反晶体凹陷。衬底可以由硬质金属组成，优选由WC和Co组成。可以将CVD金刚石层施加到功能表面。在至少一个金刚石涂层的功能表面的情况下，通过能量色散X射线荧光测量的表面的钴含量（以重量％表示）相对于WC，仅通过与未处理的底物相比最大为50％。在根据本发明的方法中，基板表面上的硬质材料颗粒通过化学蚀刻以凹坑或孔的形式形成凹陷的方式进行晶化腐蚀。
