摘要
采用微弧氧化法在纯钛表面制备TiO_2孔径在400 nm左右的介孔层,同时用电化学脉冲沉积法将铜沉积在介孔层上,对改性层进行滑动摩擦实验,利用扫描电镜、激光显微镜对改性层的表面形貌、磨损后深度进行了表征。结果表明,TiO_2纳米介孔层会对沉积铜的粒径的大小、形状产生影响;试样的磨损机制主要表现为犁沟磨损、粘着磨损及和磨粒磨损;二氧化钛介孔层及铜粒径的存在提高了纯钛的抗磨减磨性能。
The mesoporous layer with the pore size of about 400 nm was prepared on the surface of pure titanium by micro-arc oxidation. The copper was deposited on the mesoporous layer by electrochemical pulse deposition method. The modified layer was subjected to sliding friction experiment. The surface morphology and wear depth of the modified layer were characterized by scanning electron microscope and laser microscope. The results show that the nano-mesoporous layer will affect the particle size and shape of the deposited copper. The wear mechanism of the sample is mainly expressed by furrow wear, adhesive wear. and abrasive wear; titanium dioxide mesoporous layer and the presence of copper particle size to improve the anti-wear properties of pure titanium.
