盐雾腐蚀对DLC薄膜摩擦学性能的影响

Influence of Salt Spray Test to DLC Film on Tribological Properties

  • 摘要: 利用中频磁控溅射法分别在304不锈钢、GCr15和9Cr18 3种不同基底上沉积了Ti掺杂的含氢DLC薄膜. 并利用球-盘摩擦试验机考察了在中性盐雾试验条件下三种不同基底的DLC薄膜在经过不同时间盐雾试验后的摩擦学性能,同时分析讨论了盐雾试验后薄膜摩擦学性能产生变化的原因. 结果表明:在中性盐雾试验条件下暴露不同时间后,样品的耐腐蚀性能与基底材料一致;盐雾试验后沉积在三种不同基底上的薄膜跑合时间均明显增大并且GCr15基底的薄膜增长最明显;盐雾试验前后304不锈钢基底薄膜的摩擦寿命几乎没有变化而GCr15和9Cr18基底的薄膜由于发生腐蚀其摩擦寿命大幅降低约50%.

     

    Abstract: Hydrogenated DLC films were deposited on 304 stainless steel, GCr15 and 9Cr18 substrates by mid-frequency reactive magnetron sputtering. A ball-on-disk reciprocating tribometer was used to investigate the tribological properties of the films deposited on different substrates before and after different salt-spray exposure time. After that, the reasons leading to changes of tribological properties before and after salt spray test were discussed. The results show that after exposed to natural salt spray environment with different time, the corrosion resistance of different samples was accordance with their substrates. And after salt spray test, running-in period time of all films deposited on different substrates increased markedly especially the sample deposited on GCr15 substrate. What’s more, the wear life of film deposited on 304 stainless steel substrate before and after salt spray test nearly had no change but samples deposited onGCr15 and 9Cr18 substrates decreased approximately 50% due to corrosion.
