TiAlSiN 和 CrAlSiN 纳米复合涂层摩擦力学行为的高温研究

基本信息

项目摘要

PVD-coatings are an already established concept for the functionalization of surfaces of cheap substrate materials in order to improve the performance and service life of components without using solid components made of expensive special materials. Until now, tools coated by means of thin-film technology are frequently used in the cutting and cold forming industry, even though these coating systems do not offer sufficient wear resistance and mechanical properties at higher operating temperatures.By using nanocomposite layers, which are developed in the context of the proposed research project, the temperature limitations are expanded by alloying silicon in ternary coating systems (CrAlN and TiAlN) to obtain a thermal and oxidation resistant PVD-coating. Therefore, the influence of different process parameters and PVD technologies on TiAlSiN and CrAlSiN coatings is investigated to determine the correlations between the parameters and the resulting properties of the coating. Especially the influence of different substrate treatment methods, the silicon content, the target power, and the bias voltage on the morphological, mechanical and tribological properties at different temperature levels (20, 250 and 500°C) are closely investigated and evaluated. The investigations are completed by tests carried out in Taiwan, concerning the fatigue behavior at elevated temperatures. The deposition of the PVD coatings at the Institute of Materials Engineering are produced by using the magnetron sputtering process. At the same time, identical coating systems are deposited at a Taiwanese cooperating partner institute by means of an arc-evaporation process. This approach offers the opportunity to compare the different nanocomposite layers regarding their properties and to identify process specific characteristics. Finally, the layers (CrAlSiN and TiAlSiN) with the best properties of both different deposition processes are applied on forming tools and their performance is tested and evaluated in a real forming process with increased operating temperatures.
PVD涂装是廉价基材材料表面功能化的已经建立的概念,以提高组件的性能和使用寿命,而无需使用由昂贵的特殊材料制成的固体组件。 Until now, tools coated by means of thin-film technology are frequently used in the cutting and cold forming industry, even though these coating systems do not offer sufficient wear resistance and mechanical properties at higher operating temperatures.By Using nanocomposite layers, which are developed in the context of the proposed research project, the temperature limitations are expanded by alloying silicon in ternary coating systems (CrAlN and TiAlN) to obtain a thermal and oxidation resistant PVD涂层。因此,研究了不同的过程参数和PVD技术对Tialsin和Cralsin涂层的影响,以确定参数与所得涂层所产生特性之间的相关性。特别研究并评估了不同温度水平(20、250和500°C)在不同底物处理方法,硅含量,目标功率以及偏置电压对形态,机械和摩擦学特性的影响。投资是由在台湾进行的测试完成的,这些测试涉及温度升高时的疲劳行为。 PVD涂层在材料工程研究所的沉积是通过使用磁性溅射过程产生的。同时,相同的涂料系统通过弧形蒸发过程存放在台湾合作伙伴研究所。这种方法提供了比较有关其性能的不同纳米复合层并确定过程特定特征的机会。最后,将两种不同沉积过程的最佳特性的层(Cralsin和Tialsin)应用于形成工具,并在实际形成过程中测试和评估其性能,并随着工作温度的升高。
