标准范围

ISO 14577-4:2007规定了一种测试涂层的方法，该方法特别适用于薄涂层纳米/微米范围内的测试。当压痕垂直于试件表面进行时，本试验方法仅限于检查单层，但如果单个层或梯度的厚度大于压痕过程的空间分辨率，也可以在横截面上测量梯度和多层涂层。试验方法不限于任何特定类型的材料。金属、非金属和有机涂层包含在ISO 14577的范围内-4:2007.ISO 14577-4:2007关于硬度测量的应用仅在压头为棱锥体或圆锥体且尖端曲率半径小到足以在涂层内发生塑性变形的情况下才可行。粘弹性材料或表现出显著蠕变的材料的硬度将受到试验时间的强烈影响。

ISO 14577-4:2007 specifies a method for testing coatings that is particularly suitable for testing in the nano/micro range applicable to thin coatings.This test method is limited to the examination of single layers when the indentation is carried out normal to the test piece surface, but graded and multilayer coatings can also be measured in cross-section if the thickness of the individual layers or gradations is greater than the spatial resolution of the indentation process.The test method is not limited to any particular type of material. Metallic, non-metallic and organic coatings are included in the scope of ISO 14577-4:2007.The application of ISO 14577-4:2007 regarding measurement of hardness is only possible if the indenter is a pyramid or a cone with a radius of tip curvature small enough for plastic deformation to occur within the coating. The hardness of visco-elastic materials, or materials exhibiting significant creep will be strongly affected by the time taken to perform the test.
