在腐蚀性介质中工作的各种摩擦副由于腐蚀及磨损的协同作用造成材料的流失是严重的。解决问题的办法除选材(包括开发新材料或其他表面强化措施)外,还可考虑采取保护措施。业已证实阴极保护法在腐蚀磨损条件下仍然适用,但对氢脆敏感材料如钛合金不可过保护,否则将引起氢致磨损;阳极保护法在低载下尚可,高载下由于表面膜破裂成块剥落造成材料流失更加严重,一般不宜使用。采用添加剂的报导在国内外尚不多见。有人研究过微动磨损及冲蚀条件下添加剂的作用,如用Na_2Cr_2O_7、NaNO_2、Na_2MoO_4、硼砂及苯甲酸盐、表面活性剂等作为缓蚀剂或润滑剂都能不同程度地降低材料的流失。本工
The loss of material due to the synergistic effect of corrosion and wear of various friction pairs working in corrosive media is serious. Solution to the problem In addition to material selection, including the development of new materials or other surface hardening measures, protective measures may also be considered. It has been confirmed that the cathodic protection method is still applicable under corrosive wear conditions, but not sensitive to hydrogen embrittlement sensitive materials such as titanium alloy, otherwise it will cause hydrogen induced wear; anode protection method is acceptable under low load, due to rupture of the surface film under high load Blocking caused by material spalling more serious, generally should not be used. The use of additives reported at home and abroad are rare. Some people have studied fretting wear and erosion under the conditions of additives, such as the role of Na_2Cr_2O_7, NaNO_2, Na_2MoO_4, borax and benzoate, surfactants, etc. as a corrosion inhibitor or lubricant can reduce the loss of materials to varying degrees .
