Surface Engineering Method to fabricate a bendable self cleaning Surface with high robustness
Science of Advanced Materials, 2013Co-Authors: Weiwei Wu, Li Cheng, Miaomiao Yuan, T JingAbstract:Self-cleaning is a common phenomenon in natural world and has wide applications in people's real life. Here we report a general Surface Engineering Method to fabricate micro/nano hybrid structure on polymer film, which can be applied to other substrates. The modified polymer Surface is superhydrophobic with a water contact angle (CA) of 160 +/- 1 degrees and a water sliding angle (SA) of 3 degrees. When bent to two opposite directions, the convex Surface and concave Surface are still superhydrophobic and exhibit self-cleaning property. Dusts with different sizes can be cleared away from the modified Surface by dipping water drops or spraying water mist. The Surface Engineering Method modified Surface has ultrahigh robustness. Its perfect multi-scale hierarchical structure and self-cleaning property barely change even after undergoing one hour ultrasonic oscillation. This Method is applicable to modify the Surfaces of various materials, architectures and devices into self-cleaning Surfaces.

effects of nitriding temperature on microstructures and vacuum tribological properties of plasma nitrided titanium
Surface & Coatings Technology, 2015Co-Authors: Zhiqiang Fu, Chengbiao Wang, Xingkuan YangAbstract:Abstract Facing the outer space application of titanium and its alloys in drilling pipes and drilling robots, it is necessary to find an optimized Surface Engineering Method to improve their vacuum tribological properties. In order to find an optimized nitriding temperature, a series of plasma nitriding experiments were carried out for commercial titanium (UNS R50400/Gr. 2/TA2/CP3) at various temperatures ranging from 650 to 950 °C for 8 h to investigate the effects of nitriding temperature on microstructures and mechanical properties. Vacuum tribological properties of the nitrided and untreated samples were examined using a ball-on-disc vacuum tribo-meter. The results show that the wear resistance of titanium tested under vacuum condition is effectively enhanced, due to the formation of the hard nitrided layer. The Surface roughness, thickness and hardness of the nitrided layer increase with the increase of nitriding temperature. Nevertheless, the load bearing capacities of the samples nitrided at 900 and 950 °C are much lower than those of the samples nitrided at 800 and 850 °C. Therefore, the wear volume keeps dropping at the nitriding temperature from 650 to 850 °C, whereas, it converts to rise up when the nitriding temperature is above 850 °C. In general, it is an optimized process to be nitrided at the temperature of 850 °C for 8 h to improve the vacuum tribological properties of titanium.
