Based on the above straight lines, the contact zone can be determined from the known indentor curvature and loading.

根据这些直线族，可以由已知的压头曲率和外载荷确定接触区尺寸。

The fracture toughness KIC of TiAlN coating has been measured by Weishi indenter indentor and the appearance of impress has also been observed by SEM.

并采用维氏压头测量断裂韧性KIC和通过扫描电子显微镜观察压痕形貌来评定涂层的韧性。
