Abstract The HVOF spraying parameters of CoCrW coating were optimized by using four factors and three levels orthogonal test method， the microstructure of coating was taken as objective to analyse the results and the adhesion strength of coating with substrate prepared by using optimized parameters were tested. The results show that the best process parameters is 897 L/min for the oxygen flow， 22 L/h for the kerosene flow， 66 g/min for the feed rate and 340 mm for the spray distance. The adhesion strength of CoCrW coating with substrate is 69.7 MPa at these parameters. The analysis shows that in HVOF spraying process， high-speed moving particles impact the matrix to produce shot peening effect. At the same time， kinetic energy is converted into thermal energy in a short time， which makes molten particles produce secondary plasticization at the interface. It is beneficial to the rapid spreading of the molten droplets， enhances the compactness of the coating and improves the bonding strength between the coating and the substrate.
