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。

A total of five different structural configurations representing different stiffness ratios between the wood-frame structure and concrete frame were tested.

Firstly, we investigate the influence of the hole injection layer on the performance of the OLED. Evidence shows that m-MTDATA exhibits a dense film structure and fine surface morphology, leading to easy hole migration. Furthermore, a low-voltage driving of OLEDs has been achieved by doping 4F-TCNQ into m-MTDATA layer. Secondly, we obtain a highly efficient OLED by using a new oxidiazoles, an efficient electron-transporting molecular materials. Finally, we have realized the efficient electron injection and transport in organic light-emitting diodes using an electron-transport layer composed of BPhen with Liq co-deposited layer. With this cohost strategy, we improve the power efficiency by～21 % while reduce the driving voltage by～13%.

首先研究了不同空穴传输层对有机电致发光器件的影响，结果表明，由于m-MTDATA具有良好的成膜性，以及空穴注入能力，可以改善空穴向发光层的注入，提高了器件的效率，进一步在m-MTDATA中掺入4F-TCNQ可以显著降低器件的驱动电压；其次，利用一种新型含氟噁二唑类衍生物做电子注入层获得了高效有机薄膜电致发光器件；最后，研究了Bphen：Liq混合层的电子传输特性，表明混合层的电子传输能力显著提高，基于共基质电子传输层的器件的电压比传统器件降低了13％而效率却提高了21％。
