摘要：This study investigated the effects of surface texture in a compressor impeller shaft on its remanufacturing using high-velocity oxy-fuel (HVOF). Nine main types of surface texture were prepared. The HVOF system was used to remanufacture samples related to the appearance of these surface texture features, and the samples without texture were selected as the control group. The performance of remanufactured samples was evaluated by the scratch method. The effect of the surface texture factor level on first cracks that occurred (critical load LC1) was investigated using the analytic hierarchy process (AHP) method. The levels of various factors that influence the indicator weight, as well as the preferred combination, were determined. The representative crosssectional morphologies and element distribution of the preferred coated samples were investigated using scanning electron microscopy (SEM) and elemental line scanning, respectively. Results indicate that the coating combined with the substrate mainly through a mechanical method, and adhesion strength was substantially improved via a suitable surface texture. It can be concluded that fabricating a suitable surface texture is an effective way to improve the coating adhesion strength of the shaft remanufactured using HVOF.
