摘要：Mechanical and tribological properties of Ti coating deposited by physical vapour deposition (PVD) technique using electron beam to activate evaporation of Ti onto steel OKhN3MFA are evaluated. The thickness and grain growth direction are assessed by means of scanning with an electron microscopy,chemical composition of both the coating and substrate are measured using EDX. The coefficient of friction (COF) and wear was evaluated by a Pin-on-disc test. The wear of the coating was expressed as a loss of material (volume and mass) after the Pin-on-disc test. Hardness and Young’s modulus were found to be from 3.8 GPa to 7.6 GPa and from 65 GPa to 200 GPa,respectively. The measured values of the studied properties were compared with the literature data for Ti PVD coatings.
