Studies on the preforming of steel in semi-hot temperature range with modified carbon-based coating systems

该研究项目的目的是开发类金刚石（DLC）层体系，该体系可用于钢的温锻耐磨涂层。以往的研究表明，DLC涂层体系比其他涂层体系（如CrN）具有更好的耐磨性能。第二阶段的目标是量化这些性能，并提高DLC层系统的耐磨性。基于第一个项目期间的结果，DLC层将进一步开发。要做到这一点，将使用三种不同的方法。为了表征磨损过程，将在长期试验中研究最合适的涂层系统。除第一阶段外，还将研究不同的工件温度。此外，还研究了润滑油的影响。最后，第二次资助的成果将用于扩展第一次资助期的磨损模型。

The aim of the research project is the development of diamond-like carbon (DLC) layer systems which can be used as wear-resistant coatings for warm forging of steel. In previous studies it was demonstrated that DLC layer systems have better wear properties than other coating systems lika (CrN). The aim of the second period is to quantify these properties and to increase the wear resistance of the DLC layer systems.Based on the results of the first project period the DLC layers will be further developed. To do that three different approaches will be used. To characterize the wear process, the most suitable coating systems will be studied in long-term tests . In addition to the first period different workpiece temperatures will be investigated. Furthermore the influence of lubricants will be investigated. Finally, the results of the second funding will be used to extend the wear model of the first funding period.
