This study investigated the effects of deposition techniques on the microstructural and tribological properties of Ti/TiN/TiCN/TiAlN multilayer coatings onto a Custom 450 steel substrate. The coatings were produced using cathodic arc physical vapor deposition (CAPVD) and plasma-assisted chemical vapor deposition (PACVD). The microstructural of the coatings was evaluated using (SEM), and phase f...

Subject of research: the article studies effect continuous ion beams Ar++Zr+ and N++Ti+ compositions, with energy E = 20 keV radiation dose D 5⸱1017 ion/cm2, on change in morphology, microhardness wear resistance during finishing turning processing metal-cutting plates made tungsten-free hard alloy grade KNT16 (TiCN-Ni-Mo).
 The purpose study: development technological modes ion-beam aimed...

For residual stress evaluation in complex substrate-coating-systems, energy-dispersive (ED) diffraction with energies up to 100 keV can be applied to analyze the near interface residual stress state in the substrate, because the high energy white beam penetrates the coating completely. By the example of an Al2O3/TiCN on WC coating system we have studied the feasibility for using the coating ref...

In recent years, improving the mechanical properties of metals has become the main challenge in the modern materials and metallurgical industry. An alloying process is usually used to achieve advanced performance of metals. This paper, however, describes an alternative approach. Modification with ceramic nanoparticles, gas-dynamic treatment (GDT) and a combined treatment were investigated on a ...

The increasing use of titanium and its alloys in the manufacture implants results from simultaneous presence excellent biocompatibility, relatively low density, high mechanical properties, corrosion resistance. Unlike application characteristics, is classified as a difficult-to-machine material. Therefore, one constant challenge for implant manufacturers to correctly choose turning tools each a...
