Abstract:

Advanced innovative coatings with self-organized graded structure are presented. Magnetron sputtering (MS), ion implantation assisted MS, pulsed electrospark deposition (PED) and chemical reaction assisted PED (CRAPED) methods has been applied for production of multicomponent nanostructured thin and thick coatings with multilayer and graded structure. Few classes of advanced coatings were developed and presented: hard multicomponent coatings with high thermal stability and heat resistance in systems Ti-Al-Si-C(N), Ti-Cr-Si-C(N), Cr-Al-Si-B(N), Mo-Si-B(N), Zr-Si-B(N), multilayer heat-generating coatings. PED allows depositing of fine-grained, hard, and wear-resistant WC-Co coatings with wide transition zone and naturally graded distribution of elements through the thickness. PED- coatings with a high amount of MAX phase were obtained onto Ti substrate using the Cr2AlC electrode.
