保护性氧化 meaning in Chinese
protective oxidation
Examples
- A dense protective scale , mainly a - al2o3 , formed on the surface of the samples , which could prevent samples from further oxidation . it was helpful to improve its high temperature oxidation resistance and shed new light on the application in high temperature circumstance
试样表面形成了一层主相为a一a12o3的致密保护性氧化膜，阻止了材料的内层发生进一步的氧化，从而极大地提高了材料的高温抗氧化性，为ti3sicz材料在高温条件下的应用提供新的研究思路。 - Owing to the interfacial cracking which occurs under higher applied load conditions , the composite with high content of tib _ 2 phase exhibited a transition from mild wear to severe wear over the applied load range from 10 n to 80 n . under moderate applied load , increasing the sliding speed caused a decrease in wear rate and friction coefficient of the in - situ composites because the formation of a protective oxide film occurred on the sliding surface and the hardness of the subsurface layer was maintained due to reinforcement of tib2 nanoparticles in the cu matrix
随着载荷的增加， cu -纳米tib2原位复合材料的磨损率和摩擦系数增加；由于在较高载荷下发生表面开裂，高含量的tib2相增强原位复合材料发生了由轻度磨损向严重磨损形式的转化。在中等载荷下由于表面保护性氧化膜的形成和基体中纳米tib2相的存在使复合材料具有良好的抗软化能力， cu -纳米tib2原位复合材料的磨损率和摩擦系数随着滑动速度的增加而下降。
