采用电感耦合等离子体辅助反应溅射法在316不锈钢（316 SS）基体上制备了一系列含Cr氢化非晶碳（a-C：H：Cr）涂层。在a-C：H：Cr和316 SS之间沉积具有100、200和300 nm的不同厚度的元素Cr中间层。对沉积的a-C：H：Cr/Cr/316 SS试样进行了详细的成分、结构和力学性能表征。用扫描电子显微镜原位测量了a-C：H：Cr层、Cr层和a-C：H：Cr/Cr/316 SS界面区域的断裂韧性值。测得的a-C：H：Cr/Cr/316 SS界面区域的断裂韧性表现出近似线性相关性与发生在Cr夹层中的断裂表面的面积分数，表明界面断裂韧性取决于裂纹扩展的详细路径，并表明界面韧性可以通过界面区域的材料设计来设计。
A series of Cr-containing hydrogenated amorphous carbon (a-C:H:Cr) coatings were deposited onto 316 stainless steel (316SS) substrates using inductively coupled plasma assisted reactive sputter deposition. Elemental Cr interlayers with different thicknesses of 100, 200, and 300 nm were deposited between a-C:H:Cr and 316SS. Detailed composition, structure, and mechanical behavior characterization of deposited a-C:H:Cr/Cr/316SS specimens were performed. Fracture toughness values of the a-C:H:Cr layer, the Cr layer, and the a-C:H:Cr/Cr/316SS interfacial regions were measured by bending of microcantilever beams with focused ion beam milled pre-notches in-situ a scanning electron microscope. Measured fracture toughness of a-C:H:Cr/Cr/316SS interfacial regions exhibits an approximately linear correlation with the area fraction of the fracture surface occurring in the Cr interlayer, indicating that the interfacial fracture toughness depends on the detailed path of crack propagation and suggesting that interfacial toughness can be engineered through materials design of the interfacial region.
