Investigation of tribological behaviour of NiCrSiBFe coating on SS 316L sliding against AISI 52100 bearing steel, alumina (Al2O3), and silicon nitride (Si3N4) under dry conditions carried out. Air Plasma Spraying (APS) and High Velocity Oxy Fuel (HVOF) thermal spraying methods used to deposit the coatings. The dry sliding wear tests were carried out with the ball on disc machine following the ASTM G99 standard and the normal loads used were 10N, 15N, and 20N along with the constant sliding velocity of 0.5 m s−1 at room temperature. The particle analysis, XRD, SEM, EDX, and nanoindentation were used for the characterisation of the powder, coatings, and worn surfaces. The spraying methods, counter materials, and normal loads were ranked based on the wear loss and coefficient of friction. The main wear mechanisms on the coating's wear track are abrasive and adhesive. The HVOF spraying method revealed enhanced wear resistance property as compared to the plasma-sprayed coating.
