Cr2O3 and TiO2 powders were deposited by atmospheric plasma spray (APS) on steel substrates. Microstructural analysis of the coatings showed typical lamellar structure with good coating quality. Fatigue strength was studied using cyclic testing (measuring an inhouse-built apparatus coated systems under a wide range impact cycles) static loading tests (Vickers standards 600N 1500N) measuring adh...
