Fe-based amorphous coatings have promising applications in the field of surface protection. However, due to their brittle characteristics, delamination has become the most common wear mechanism of the coating. In present study, influences of structural relaxation and crystallization on microstructure, hardness and dry-sliding tribological behavior of the coatings are investigated. The results indicate that wear resistance of the coating could be enhanced by structural relaxation, although there is no obvious change of the hardness. Hardness of the coating increases obviously after crystallization due to the massive formation of brittle crystals, however, the coating only exhibits lower wear rate under lower applied load, but the wear rate increases drastically with applied load because brittle crystals increase brittleness of the coating and cause severe delamination of the coating under higher applied loads.

铁基无定形涂层在表面保护领域具有广阔的应用前景。然而，由于它们的脆性，分层已经成为涂层最常见的磨损机理。在本研究中，研究了结构弛豫和结晶对涂层的微观结构，硬度和干滑摩擦性能的影响。结果表明，尽管硬度没有明显变化，但通过结构松弛可以提高涂层的耐磨性。结晶后，由于脆性晶体的大量形成，涂层的硬度明显增加，但是，涂层仅在较低的施加载荷下表现出较低的磨损率，
