研究了未捆绑多壁碳纳米管（MWCNTs）涂层纯钛（Ti）板的摩擦学性能和磨损行为。在Ti衬底上形成网状结构的MWCNT薄膜，并在干滑动条件下用球盘式磨损试验装置检测其摩擦学性能。本次试验采用SUS304不锈钢球作为对应材料。与未涂覆任何涂层的纯钛板相比，涂覆MWCNTs的Ti板的平均摩擦系数显著降低且稳定。SEM-EDS分析表明，经过3.6 ks的滑动磨损试验后，网状结构的MWCNT膜明显保留，未出现与SUS304球一起的断裂现象。上述优异的摩擦学性能是由于碳纳米管的自润滑作用、其承载作用以及钛板与MWCNT薄膜之间通过退火形成的强冶金结合。
This study investigated the tribological property and wear behavior of pure titanium (Ti) plate coated with un-bundled multi-walled carbon nanotubes (MWCNTs). The network-structured MWCNT films were formed on Ti substrate, and their tribological properties were examined by the ball-on-disk wear test equipment under dry sliding condition. SUS304 stainless steel ball was used as a counterpart material in this test. The mean friction coefficient of the Ti plate coated with MWCNTs was remarkably lower and stable compared to the as-received pure Ti plate without any coating films. SEM-EDS analysis showed the network-structured MWCNT films obviously remained after wear test for 3.6 ks in sliding and no seizure phenomena with the SUS304 ball. The above excellent tribological performance was due to CNTs self-lubricant, their bearing effects and the strong metallurgical bonding between Ti plate and MWCNT films by annealing.
