一种AZ91D镁合金零件涂层
摘要：
本发明公开了一种AZ91D镁合金零件涂层，其特征在于：一种AZ91D镁合金零件涂层是在零件设一表面材料层，表面材料层的主要成份为Ni-Cr-Ce-La-In，且含Ni不少于80%（wt%）、Cr不少于10%（wt%）、含Ce量为0.5%～1.5%（wt%）、含La量为0.4%～1%（wt%）、含In量为0.4%～0.6%（wt%）,表面材料层的不少于75%微晶单元或微粒的直径或长度尺寸在1～1500nm、不同微晶单元或微粒紧密结合，零件表面材料层和基体材料成为一体、且大于30%的零件表面材料层与基体材料接触表面面积的零件表面材料层和基体材料原子有序区距离不大于为4nm，形成一种AZ91D镁合金零件涂层。
摘要（英）：

The invention discloses an AZ91D magnesium alloy part coating. The AZ91D magnesium alloy part coating is characterized in that a surface material layer is arranged on a part; the main components of the surface material layer are Ni-Cr-Ce-La-In; Ni is not less than 80 wt%; Cr is not less than 10 wt%; Ce ranges from 0.5 wt% to 1.5 wt%; La ranges from 0.4 wt% to 1 wt%; In ranges from 0.4 wt% to 0.6 wt%; the diameter or length of microcrystalline units or fine particles not less than 75% of the surface material layer is 1-1500 nm; the different microcrystalline units or fine particles are tightly combined; the surface material layer of the part and a substrate material are integrated; the distance between the part surface material layer and an atomic orderly area of the substrate material of more than 30% of the contact surface area of the part surface material layer and the substrate material is not larger than 4 nm, and the AZ91D magnesium alloy part coating is formed.
