汽车工业零件日常制造中使用的表面处理是为了满足大规模生产的功能和装饰要求而选择的。负载增加（机械、热等），现代汽车系统需要更长的寿命、减轻重量、减少摩擦和耐腐蚀性。在过去的十年中，在PVD、PECVD、热化学热处理和热喷涂方面开发了改进的和新的沉积技术。这些新的处理方法在动力系统和发动机应用中越来越普遍。为不同类型的基体材料（如铝合金、表面硬化钢等）生成优化的表面并且几何形状（例如孔）也影响运行成本。由于这些相互竞争的表面处理技术的新发展，用先进的处理技术取代传统的处理-基材-系统变得越来越普遍。将展示不同表面处理的应用潜力和选定示例。详细讨论了等离子喷涂发动机内孔内涂层、IONITOX工艺对动力总成部件的防腐蚀特性以及活塞环处理。
Surface treatments used in daily manufacturing of parts for the automotive industry are selected to serve functional and decorative requirements achieved by mass production. Increased loads (mechanical, thermal, etc.), longer lifetime, weight reduction, friction reduction, and corrosion resistance are demanded for modern automotive systems. Within the last decade, improved and new deposition techniques were developed in PVD, PECVD, thermochemical heat treatment and thermal spraying. These new treatments are becoming more and more common in powertrain and engine applications. Generating optimized surfaces for different types of substrate materials (e.g. Al-alloys, case hardened steels, etc.) and geometries (e.g. bores) also impacts the running costs. Due to the new developments within these competing surface treatments, it becomes more and more common to substitute traditional treatment-substrate-systems with advanced treatments. Both the application potential and selected examples of different surface treatments will be shown. Aspects of the internal coating of bores inside the engine by plasma spraying, features of the corrosion protection of parts for the powertrain by the IONITOX process and piston ring treatments are discussed in more detail.
