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 micro-arc oxidation method was used to prepare the mesoporous TiO_2 with a diameter of about 400 nm on the surface of pure titanium. At the same time, the copper was deposited on the mesoporous layer by electrochemical pulse deposition method. The sliding friction test was carried out on the modified layer. The surface morphology of the modified layer and the depth after wear were characterized by laser microscope. The results show that the TiO 2 nano-mesoporous layer will affect the size and shape of the deposited copper. The wear mechanism of the sample mainly includes furrow wear, adhesive wear and abrasive wear; the mesoporous layer of titanium dioxide and the particle size of copper The existence of pure titanium anti-wear and anti-wear properties.
