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。
