The objective of this research project is the manufacturing of CVD diamond coated tools with high process stability. The influencing factors on the tool lifetimes of CVD diamond coated tools has been the research focus in a fundamental research project of the Institute for Machine Tools and Factory Management (IWF) of TU Berlin. The results of the preceding project showed that the complex interaction of cemented carbide substrate, pre-treatment, tool geometry and coating thickness as well as in particular the residual stresses of substrate and coating must be understood and optimized in order to produce a high coating adhesion. Within this transfer project, the fundamental research results obtained shall be implemented with three partner firms, each specialized in one step of the production process. Furthermore, the spectrum of CVD diamond coated tools shall be widened by focusing also on ceramic tools and Multi-Layer CVD diamond coatings.

该研究项目的目的是制造具有高过程稳定性的CVD钻石涂层工具。 CVD钻石涂层工具的工具寿命的影响因素一直是TU柏林TU机床和工厂管理研究所（IWF）的基本研究项目的研究重点。上一个项目的结果表明，必须理解和优化胶结碳化物底物的复杂相互作用，预处理，工具几何形状和涂料厚度，尤其是底物和涂层的残留应力，并进行优化，以产生高涂层粘附力。在此转移项目中，获得的基本研究结果应与三家合作伙伴公司一起实施，每个公司都在生产过程的一步中进行专业。此外，CVD钻石涂层工具的光谱也应通过聚焦在陶瓷工具和多层CVD钻石涂料上来扩大。
