Manufacturing of CVD diamond coated tools with high process stability

该研究项目的目标是制造具有高工艺稳定性的CVD金刚石涂层工具。CVD金刚石涂层刀具寿命的影响因素一直是柏林工业大学机床与工厂管理研究所（IWF）基础研究项目的研究重点。上述项目的结果表明，必须了解和优化硬质合金基体、预处理、刀具几何形状和涂层厚度之间的复杂相互作用，特别是基体和涂层的残余应力，以产生高涂层附着力。在该转让项目中，所获得的基础研究成果将与三家合作伙伴公司共同实施，每家公司都专门从事生产过程的一个步骤。此外，CVD金刚石涂层工具的范围应通过关注陶瓷工具和多层CVD金刚石涂层来拓宽。

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.
