显微硬度负荷依存性现象及其本质

涂层的超显微硬度值不仅取决于涂层材料，还与测试负荷和膜层的厚度密切相关．论述了显微硬度在微小负荷范围内因测试负荷变化而发生明显变化的现象，即所谓的压痕尺寸效应，并讨论了显微硬度试验时测试负荷的正确选择和压痕尺寸效应的若干解释．

Indentation Size Effect on Microhardness and It''s Essence

The ultramicrohardness value of coatings depends not only on the coating material, but also on the applied load and film thickness. This paper is concerned with the apparent change of microhardness value with the change in an indentation size, namely, the indentation size effect (ISE). How to select the correct test load and some of the possible explanations of ISE are discussed extensively.
