Effect of halide concentration on tribocorrosion behaviour of 304SS in artificial seawater

Recently, increasing efforts have been made to study the tribocorrosion mechanism and influencing factors, and yet little relevant to the influence of electrolyte characteristics. In this work, the dependence of tribocorrosion on halide ions concentration in seawater is taken into consideration, and it follows that halide can improve solution lubricity and reduce friction coefficient and wear rate remarkably. However, high halide ions concentration may increase the corrosion susceptibility of 304SS, especially pitting susceptibility. Although over the entire range of halide ions concentration corrosion and wear interact positively, high halide ions concentration is beneficial for decreasing total material loss.
