The aim of the work was to investigate the resistance to cavitation erosion and sliding wear of sprayed HVOF coatings. M(Ni,Co)CrAlY and Cr3C2-NiCr based coatings were deposited using HVOF method onto stainless steel substrate grade AISI 304. As-sprayed coatings’ surface morphology was examined by SEM-EDS and profilometer methods. Cavitationerosion tests were conducted in distilled water with the use of vibratory rig and stationary specimen method. Cavitation erosion curves were plotted as well as cavitational wear mechanism was observed with the use of SEM microscope. Sliding wear tests were performed using the ball-on-disc tribotester with counter-specimen (ball) made of steel 100Cr6. Wearrates and coefficient of friction were computed. Normalized wear resistance with referenceto stainless steel reference sample AISI 304 was calculated. In addition, comparable analysis of wear resistance results was conducted. M(Ni,Co)CrAlY coating presented the highest cavitation erosion resistance, therefore Cr3C2-NiCr coating represented the highest sliding wear resistance of all tested materials.
