Tribological Properties of Vanadium Nitride Coated AISI 52100 Steel

Abstract:

In the present study, the wear and friction behaviour of vanadium nitride coated AISI 52100 steel against hardened AISI D2 steel disc was studied using ball-on-disc arrangement. Vanadium nitride coating treatment was performed on pre-nitrided AISI 52100 steel balls using thermo-reactive diffusion techniques. The presence of VN and V₂N phases in the coating layer was confirmed by X-ray diffraction analysis. Friction and wear tests were carried out at dry test conditions under 2.5 N, 5 N and 10 N loads at 0.1 m/s, 0.2 m/s and 0.3 m/s sliding speeds. The results showed that the friction coefficient values of vanadium nitride coated AISI 52100 steel balls against hardened AISI D2 steel disc are changing between 0.49 and 0.71, depending on test conditions. The wear rates of the vanadium nitride coated AISI 52100 steel is ranging from 6.704×10⁴ mm³/m to 2.619 × 10⁶ mm³/N m. In general, the wear rate increased with the increase in load and sliding speed.
