Warm forged components have better surface properties and higher dimensional accuracy than hot forged components. Diamond-like-carbon (DLC) coatings can be used as wear protection coatings, which are anti-adhesive and extremely hard (up to 3500 HV), to increase tool service life. In the first funding period of the research project at the IPH – Institut für Integrierte Produktion Hannover gGmbH and the Institute for Surface Technology (IOT) of the Technical University of Braunschweig in cooperation with the Fraunhofer Institute for Surface Engineering and Thin Films (IST), the influence of different coating types and process temperatures on tool wear was investigated. The result is, that DLC coatings can reduce tool wear in some cases significantly, but that their service life is strongly dependent on the temperature. Coating-integrated temperature measurement could not be realised at that point, due to adhesion challenges. During the second funding period, the effect of multilayer DLC coatings on tool wear was investigated. Also, an additional method of the temperature measurement on the engraving surface using thin film sensors was developed in order to correlate the local process temperature and local layer wear. In this work, the development of and the results gathered by the thin film temperature sensors are presented, which enable for more accurate temperature measurements than commonly used thermocouples. Their functionality and durability under high loads were investigated and showed to be promising.

温锻件比热锻件具有更好的表面性能和更高的尺寸精度。类金刚石碳（DLC）涂层可用作抗磨损且非常坚硬（最高3500 HV）的耐磨涂层，以延长工具使用寿命。在IPH的研究项目的第一个资助期中，汉诺威工业大学（InstitutfürIntegrierte Produktion Hannover gGmbH）和不伦瑞克工业大学的表面技术研究所（IOT）与弗劳恩霍夫表面工程与薄膜研究所（IST）合作，研究了不同涂层类型和工艺温度对工具磨损的影响。结果是，DLC涂层在某些情况下可以显着减少工具磨损，但其使用寿命在很大程度上取决于温度。由于附着力的挑战，此时无法实现涂层集成温度测量。在第二个资助期间，研究了多层DLC涂层对工具磨损的影响。而且，开发了使用薄膜传感器在雕刻表面上进行温度测量的另一种方法，以使局部处理温度和局部层磨损相关联。在这项工作中，介绍了薄膜温度传感器的发展和结果，与常规的热电偶相比，它们可以实现更精确的温度测量。研究了它们在高负载下的功能性和耐用性，并显示出了希望。研究了多层DLC涂层对工具磨损的影响。而且，开发了使用薄膜传感器在雕刻表面上进行温度测量的另一种方法，以使局部处理温度和局部层磨损相关联。在这项工作中，介绍了薄膜温度传感器的发展和结果，与常规的热电偶相比，它们可以实现更精确的温度测量。研究了它们在高负载下的功能性和耐用性，并显示出了希望。研究了多层DLC涂层对工具磨损的影响。而且，开发了使用薄膜传感器在雕刻表面上进行温度测量的另一种方法，以使局部处理温度和局部层磨损相关联。在这项工作中，介绍了薄膜温度传感器的发展和结果，与常规的热电偶相比，它们可以实现更精确的温度测量。研究了它们在高负载下的功能性和耐用性，并显示出了希望。介绍了薄膜温度传感器的发展和收集的结果，与常用的热电偶相比，它们可以实现更精确的温度测量。研究了它们在高负载下的功能性和耐用性，并显示出了希望。介绍了薄膜温度传感器的发展和收集的结果，与常用的热电偶相比，它们可以实现更精确的温度测量。研究了它们在高负载下的功能性和耐用性，并显示出了希望。
