Abstract：

To enhance the lifetime and performance of cutting tools and wear- or corrosion- resistant performance on mechanical components, there is a growing demand for high-performance coatings. The coatings must possess a combination of properties, including relatively high hardness, excellent adhesion, wear resistance, oxidation resistance, and corrosion resistance. To meet these requirements, it is necessary to develop new coating materials and advanced synthesis methods. By integrating cathodic arc evaporation (CAE) with magnetron sputtering (MS) or high-power impulse magnetron sputtering (HiPIMS), hard coatings with diverse multicomponent compositions, superior mechanical properties, modulated residual stresses, and enhanced high-temperature properties can be fabricated. In this presentation, several nitride and oxide hard coatings, such as AlTiN, TiAlN/TiSiN, AlTiN/Cu, AlTiN/MoCu, and AlCrO, were deposited using a hybrid PVD coating system. The microstructures and mechanical properties of these coatings will be discussed.
