Thermal oxidation treatment can increase the surface hardness and elastic modulus significantly and reduce the E /H ratio of the TC4, which indicate the treatment can enhance the wear resistance of TC4 alloy. Long time treatment can increase the thickness of the oxide layer, but the outside layer is apt to desquamate during the scratching. The oxide layer closing to substrate has better bonding properties, but microcrack forms as a result of high stress loading, which lead the layer to flake off completely.

长时间的高温氧化可以增加氧化层的厚度，但在划擦过程中氧化层发生两次脱落，表明氧化层由外表层和次外层组成，外层结合力差，易发生一次脆性剥落，内层与基体的结合强度较高，但在较大载荷作用下会产生微裂纹，导致氧化层的二次剥落。

On the basis of same reason with part one of this dissertation, we think that true motive force of crack growth comes form the deviator strain energy release.

它们表明了裂纹在金属材料里的扩展过程中，起决定作用的是形状改变比能，而不是整个应变能。

The strain rate at the crack tip for the maximum dezincification coefficient was approximately 4 times as high as initially applied strain rate.

在稳态扩展阶段，裂纹尖端导致最大脱锌系数的应变速率估计约为初始应变速率的4倍左右。

Based on these, the method for analysing the thermal-mechanical problems during the film depositon is proposed, and some mechanical problems are studied which include the asympototic analysis of the stress and deformation in a nonhomogeneous material layer on a substrate and the weight function method for interface crack problems as well as the mechanics of an interface toughening induced by the dilatant transformation.
