采用钛涂层物理气相沉积法(PVD)和渗氮法结合的混合方法在AZ91D镁合金表面制备扩散氮化钛涂层。涂层由含Ti的氮化物和氧化物的薄的表层区,钛中间区和Ti-Al-Mg型扩散区组成。因涂层改善了合金的耐蚀性能,在铝基亚层上通过氮氧共渗制备涂层时,合金能够得到最好的耐蚀性能。

Composite,diffusive titanium nitride layers formed on a titanium and aluminum sub-layer were produced on the AZ91D magnesium *** layers were obtained using a hybrid method which combined the PVD processes with the final sealing by a hydrothermal *** microstructure,resistance to corrosion,mechanical damage,and frictional wear of the layers were *** properties of the AZ91D alloy covered with these layers were compared with those of the untreated alloy and of some engineering materials such as 316L stainless steel,100Cr6 bearing steel,and the AZ91D alloy subjected to commercial *** has been found that the composite diffusive nitride layer produced on the AZ91D alloy and then sealed by the hydrothermal treatment ensures the corrosion resistance comparable with that of 316L stainless *** layers are characterized by higher electrochemical durability which is due to the surface being overbuilt with the titanium oxides formed,as shown by the XPS examinations,from titanium nitride during the hydrothermal *** composite titanium nitride layers exhibit high resistance to mechanical damage and wear,including frictional wear which is comparable with that of 100Cr6 bearing *** performance properties of the AZ91D magnesium alloy covered with the composite titanium nitride coating are substantially superior to those of the alloy subjected to commercial anodizing which is the dominant technique employed in industrial practice.
