摘要：
The mechanical and tribological properties of the plasma-sprayed Cr 3C2-NiCr coatings were investigated. The aim was to assess the susceptibilities to deformation and fracture of the coatings with respect to the starting powders, coating microstructure, and indentation direction. The threshold loads and crack dimensions that the coatings might sustain in a contact event without the onset of fracture were obtained. It was found that the threshold loads of the coatings were significantly lower than those of the corresponding bulk materials considering identical hardness and fracture toughness.
