超细晶纳米金属材料具有许多特殊的力学、物理和化学性能。摩擦腐蚀是材料在磨损和腐蚀共同作用下的降解或转变过程。纳米晶材料可通过人工制备或摩擦学/摩擦腐蚀工艺获得。本文综述了纳米金属材料的磨损、腐蚀和摩擦腐蚀行为的研究进展。纳米晶化可以通过提高材料的硬度来提高材料的耐磨性，通过形成连续致密的钝化层来降低腐蚀速度。纳米晶化还可以提高材料的耐磨蚀性能，主要是通过提高表面硬度和形成保护层和润滑层来实现的。[DOI：10.2320/MATERTRA.M2015280]
Nanocrystalline metal materials with ultra fine grains have many special mechanical, physical and chemical properties. Tribocorrosion is a material degradation or transformation process due to the combined action of wear and corrosion. Nanocrystalline materials could be obtained by artificial preparation or tribological/tribocorrosion process. In this paper, studies about the wear, corrosion and tribocorrosion behavior of nanocrystalline metal materials are reviewed. Nanocrystallization could enhance the wear resistance of materials by increasing the hardness and decrease the corrosion rate by forming continuous and compact passive layer. And the nanocrystallization could also enhance the tribocorrosion resistance of materials mainly by increasing surface hardness and forming protective and lubricating surface layers.
