In this study, we examined the wear-corrosion rate of AISI-4715 pipe sections using a three-probe electrochemical controlled reciprocating tribometer. The impact of additive chemistry on the friction coefficient, as well as their associated impact on the wear rate was determined. A significant increase in the wear rate (10-times) was observed in hydraulic fracturing fluid with high total disolved solids (HTDS) compared with distilled water. Due to the boundary lubricant nature, mixing of two different organic corrosion inhibitors with HTDS water showed a significant decrease in the friction and wear response (2–3 fold). Finally, the addition of corrosion inhibitor also impacted synergistically to improve the wear-corrosion resistance. Corrosion mitigating efficacy of different inhibitor combinations were correlated well with theoretical corrosion kinetics.

在这项研究中，我们使用三探针电化学控制往复式摩擦计检查了AISI-4715管段的磨损率。确定了添加剂化学对摩擦系数的影响，以及它们对磨损率的影响。与蒸馏水相比，在具有高总溶解固体（HTDS）的水力压裂液中，观察到磨损率显着增加（10倍）。由于边界润滑剂的性质，将两种不同的有机缓蚀剂与HTDS水混合会显着降低摩擦和磨损响应（2-3倍）。最后，缓蚀剂的添加也起到了协同作用，以改善耐磨蚀性。
