| Abstract: | The large variety of brittle coating materials have become crucial materials in the fields of aerospace and national defense science and technology, and have played a great role in national economy.Fracture toughness and residual stress are important mechanical criteria of brittle coating materials. Vickers indentation method is one of the effective methods to characterize the mecha-nical properties of brittle coating materials. In this paper, the research progresses in fracture toughness and residual stress of brittle coatings are reviewed from the aspects of coating characteristics, indentation testing methods, mechanical model and experimental equipment. The characteristics and applicability of indentation mechanics models are discussed in detail. The future development direction of Vickers indentation techniques is also pointed out. |
