正确测量涂层的硬度等力学性能一直是硬质涂层生产和研究中亟待解决的问题。本文提出的采用力学探针对涂层进行两步压入的实验方法可以在未知涂层厚度的条件下通过大载荷逐步加载展示出涂层厚度对载荷选择的要求 ,从而正确选择加载载荷进行小载荷压入实验。由此方法得到的涂层硬度值和其它力学性能指标具有准确和可靠的特点 Correctly measuring the hardness and other mechanical properties of the coating has been an urgent problem to be solved in the production and research of hard coatings. In this paper, the experimental method using mechanical probe to press the coating in two steps can be loaded gradually by large load under unknown coating thickness to show the requirement of coating thickness for load selection, so that the correct choice of load for small Load into the experiment. The hardness and other mechanical properties of the coating obtained by this method are accurate and reliable
