In this paper, important and difficult contact problems are tackled for the indentation test to measure the material properties of the matrix and/or the substrate or the adhesion strength in surface engineering. First, the boundary condition equations controlling the contact are given for two dimension strength and three dimensional problems based on some approriate assumptions. Then, the semi-analytic numeral methos, i. e. Method of Lines (MOL) is adopted to simulate the indentation of the sphere-shape indenter...

Therefore, it is necessary very much to consider the contact problems in order to deal with the test correctly.

针对表面工程中测量膜基材料性能或结合强度的压入法,分析了其实验过程中所涉及的重要而又困难的接触问题。在引入适当的假设后,文中首次对二维、三维问题等一般情况,分别给出了控制接触的边界条件方程,并进一步使用半解析的数值方法——线法,针对二维情况使用,球形压头和楔形压头分别进行了数值模拟,并将计算结果和不考虑接触情况下的结果进行了比较结果表明:剪应力差别巨大,这说明接触问题的考虑对于正确地处理实际问题是非常必要的。

A wedged load test method was used to evaluate the adhesion strength of hard coatings. In this test, a wedge indenter was put in a wedge shaped groove on the sample surface and the midline of the indenter superposed with the interface of the substrate/coating exactly. Then static load was exerted until the coating cracked along the interface. Based on the critical forced condition, an equation for the adhesion strength of the coating and substrate was presented. The adhesion strength of samples with three kinds...

A wedged load test method was used to evaluate the adhesion strength of hard coatings. In this test, a wedge indenter was put in a wedge shaped groove on the sample surface and the midline of the indenter superposed with the interface of the substrate/coating exactly. Then static load was exerted until the coating cracked along the interface. Based on the critical forced condition, an equation for the adhesion strength of the coating and substrate was presented. The adhesion strength of samples with three kinds of different hard coatings were determined. The results show that the wedged load test method can be used to evaluate the adhesion strength of hard coating and substrate. The disparity of experimental data consist with the ASTMC 663-79 Standard. The results were not influenced by non stochastic factors.

提出用楔形加载法评价高强度涂层材料与基体的结合强度。该方法利用楔形压头置于有楔形槽的试样中 ,使楔形压头中心线与涂层基体界面重合 ,施加静态载荷至试样沿涂层界面开裂 ,根据试样受力边界条件 ,给出涂层与基体结合强度的公式。对三种不同涂层的基体材料进行了结合强度试验。结果表明 ,用楔形加载法可对高强涂层与基体的结合强度进行测试 ,所得数据分散度与 ASTMC633- 79标准相同 ,试验数据不受非随机因素的影响。

The necessity of the waste compaction was analyzed . Through analyzing the problem of the existing MSW transfer station compactor, a new style compactor is presented. The following experiment proved the wedge shaped compactor can enhance the compaction ratio notably in contrast with the normal compactor.
