摘要
接触表面晶粒取向对金属材料(含涂层)的摩擦及腐蚀性能均产生显著影响。综述晶粒取向对轻金属(Mg、Al、Ti)和过渡金属(Ni、Cu、Zn)摩擦及腐蚀性能影响的研究现状;指出目前研究存在的问题是对摩擦、腐蚀行为的研究缺乏实验条件的系统性,对于其微观摩擦及腐蚀机制研究不够深入。提出未来可借助于更先进的表征手段,通过精细分析磨损、腐蚀表面及亚表面微区组织、成分,来进一步探讨晶体取向对摩擦、腐蚀行为的影响;考虑滑移及原子密排因素,来解释不同晶粒取向对其摩擦及腐蚀性能的影响机制;在单一摩擦或腐蚀条件下研究晶粒取向影响的基础上,应进一步探讨在磨损腐蚀复合条件下晶粒取向对摩擦及腐蚀性能的影响。
The grain orientation of contact surface has a significant impact on the friction and corrosion properties of metal materials(including coatings).The influence of grain orientation on the friction and corrosion properties of light metals(Mg,Al,Ti)and transition metals(Ni,Cu,Zn)was reviewed.It was pointed out that the main problems in the present research is the lack of systematic experimental conditions for the study of friction and corrosion behavior and the lack of thorough understanding of the micro-friction and corrosion mechanism.It was suggested that more advanced characterization methods should be used to analyze the microstructure and composition of wear,corrosion surface and subsurface microzone so as to further study the effect of crystal orientation on friction and corrosion properties,the slip and atomic density factors should be taken into consideration for explaining the influence mechanism of different grain orientations on their friction and corrosion properties,and on the basis of studying the effect of grain orientation under single friction or corrosion condition,the effect of grain orientation on friction and corrosion properties under combined wear and corrosion condition should be further discussed.
