【摘要】：采用UMT-2多功能摩擦磨損試驗機和電化學(xué)工作站(CHI614E)考察了鍛造Co Cr Mo合金在25%小牛血清溶液條件下的摩擦腐蝕性能,利用掃描電鏡觀察了摩擦腐蝕的形貌特征,對腐蝕損失量、機械磨損損失量及腐蝕和磨損的協(xié)同損失量進行了對比分析.結(jié)果表明:鍛造Co Cr Mo合金的腐蝕電位(Ecorr)約-820 m V,在0.5~0.75 V區(qū)間出現(xiàn)二次鈍化.不同載荷條件下,摩擦腐蝕的摩擦系數(shù)均大于純摩擦系數(shù),且隨載荷的增加而減小,摩擦腐蝕電流則隨載荷的增加而增大.隨載荷的增加,機械磨損損失量所占比例增大,腐蝕損失量所占比例降低.摩擦腐蝕的協(xié)同損失量占到總損失量的30%以上,且隨載荷增加而增大.
[Abstract]:The friction and corrosion properties of forged Co Cr Mo alloy under the condition of 25% calf serum solution were investigated by means of UMT-2 multifunctional friction and wear tester and electrochemical workstation CHI614E. The morphology of friction corrosion was observed by scanning electron microscope (SEM). The mechanical wear loss and the cooperative loss of corrosion and wear were compared and analyzed. The results show that the corrosion potential of forged Co Cr Mo alloy is about -820 MV, and the secondary passivation occurs in the range of 0.5 ~ 0.75 V. Under different loads, the friction coefficient of friction corrosion is higher than that of pure friction, and decreases with the increase of load, and the friction corrosion current increases with the increase of load. With the increase of load, the proportion of mechanical wear loss increases and the proportion of corrosion loss decreases. The synergistic loss of friction corrosion accounts for more than 30% of the total loss and increases with the increase of load.
