本文研究了TC4钛合金和氧化铝陶瓷摩擦副在模拟海水下的腐蚀磨损行为。采用失重法测量磨损体积损失,利用阴极保护和电化学方法测量摩擦过程中腐蚀电流的方法来求得腐蚀磨损之间的交互作用。结果表明:在该试验条件下,TC4钛合金在海水中的腐蚀磨损量明显大于其在阴极保护条件下的磨损量,证明腐蚀与磨损有交互作用的发生。纯磨损量占总腐蚀磨损量的比例为65.9%~89.8%,在腐蚀磨损过程中磨损作用明显大于腐蚀作用.腐蚀磨损交互作用量占总腐蚀磨损量的比例ΔV/V为10.2%~34.1%,腐蚀磨损交互作用同样不可忽视. |

Corrosion-wear behaviors of TC4 alloy sliding against alumina in artificial seawater was investigated.The wear volume was determined by weight-loss method.The synergistic effect between corrosion and wear can be obtained by measuring the material loss under cathodic protection and the corrosion rate under sliding condition.In this paper,the wear caused by corrosion wear was higher than that under cathodic protection,and this was the evidence of synergistic effect.The fact that the ratio of the mechanical wear to the total wear ranged form 65.9% to 89.8% indicated mechanical wear prevailed in the corrosion-wear process.The ratio of the synergistic effect between corrosion and wear to the total wear was between 10.2% and 34.1% and therefore can not be neglected. |
