In present study, Al 2 O 3 coating has been deposited on steel substrate using HVOF process in controlled process parameters. For surface analysis SEM characterization was used to characterize the developed coating. Residual stresses, hardness, wear and COF are studied at variable sliding velocity of 0.1, 0.2, 0.3 and 0.4 m/s. It is observed that with increased sliding velocity its residual stresses, hardness, wear and COF was enhanced i.e. at 0.4 m/s, wear and coefficient of friction decreased to a value of 90 microns and 0.3, whereas its hardness was 490 HV and residual stresses was -15 MPa, increased at sliding velocity. This showed the sliding velocity dependency of the coating, with increased in sliding velocity, the coating showed better results.
