摘　　要：详细分析了压痕硬度测试方法自发展以来所研究的主要内容,即建立不同硬度之间的关系、硬度与弹性性能的关系、硬度与强度的关系、硬度与蠕变性能的关系、材料显微组织对硬度的影响以及硬度在薄膜力学测试中的应用等。其中,研究重点主要集中在建立硬度与力学性能参量之间的数学关系方面,即通过压痕硬度测试中获取的有关数据来得到相关的力学参量。同时提出了压痕硬度测试法的研究现状及存在的主要问题。The indentation experiment plays a very important role in mechanical performance testing. In recent years, various forms of indentation testing have been increasingly used to determine the material properties of specimens. The review surveys the application and significance of the techniques since developing indentation testing method, particularly the nano-indentation method. Although a lot of work study was researched, such as studying on the relation between one hardness value and the other one, the effect of the material microcosmic structure to hardness value, the application of hardness to test thin film mechanical properties, and so on, the technique was mainly used to deduce the elastic, plastic, fracture, creep, and adhesive properties of a great variety of materials, ranging from metals, ceramics, polymers, to biomaterials. Meanwhile, the study current status and the problem were discussed in instrumented indentation experiments. The technique has been extended to the testing of coating systems in order to calcula/e the individual properties of the thin coatings and the substrates.
