Description	HVOF (High Velocity Oxygen Fuel) thermal spraying technology is commonly used for component surface protection against abrasive wear. Alloy-based and cermet coatings meet demands on high abrasive wear resistance. Wear resistance is in many cases decisive property for proper component functioning. The suitable materials for particular applications are usually selected according to their different hardnesses. For this reason, the present work is focused on comparison of abrasive wear resistance and hardness of alloy- based and cermet coatings. The coatings sprayed on steel substrates were subjected to the abrasive wear test according to modified method ASTM G-65 (Rubber Wheel/Dry Sand Abrasion Test). Abrasive sand Al2O3 with grain size of (212-250) µm was used. CoCrWC (Stellite 6), NiCrBSi, CrC-NiCr, CrC-CoNiCrAlY, WC-Co powders were used to prepare sample sets subjected to the test. It has shown that the abrasive wear resistance is not directly proportional to the hardness. The difference in microstructure between cermet and alloy-based coatings results in different wear mechanisms which plays the essential role in abrasive wear resistance of particular coating.
