The mechanical properties of HVOF sprayed Cr3C2-25%CoNiCrAlY coating, determined by indentation

Popis výsledku v původním jazyce

In the paper, the experimental evaluation of basic mechanical properties such as hardness, Young elastic modulus and fracture toughness of HVOF sprayed Cr3C2-25%CoNiCrAlY coating are presented. The continuous stiffness measurement method was used to determine the coatings hardness and Young elastic modulus of single microstructure phases as well as the composite properties. The Vickers indentation with high loads was then used to evaluate the coatings indentation fracture toughness. The methodology of Chicot was used to calculate the indentation fracture toughness independently on used load, excluding the ISE effect. The measured results are compared with previously determined behavior of other CrC-based coating. Compared to them, the Cr3C2-25%CoNiCrAlY coating shown poor results considering the coating microstructure, cohesion strength and hard particle instrumented indentation hardness, but not the superficial hardness and overall coating microhardness. The not optimal spraying param
