Cr-Si Co-impregnation by Double Glow Plasma Surface Alloying Technique and Wear Resistance Improvement of γ-TiAl-based Alloy AITranslate
Abstract AITranslate
Cr-Si co-impregnation on surface of γ-TiAl-based alloy was carried out by double glow plasma surface alloying technique. Morphology, composition and phase structure were investigated by OM, SEM and XRD. The hardness of the impregnation layer was determined by micro Vickers hardness tester. The influences of Cr-Si co-impregnation on wear resistance of γ-TiAl-based alloy surface were studied through ball-disc friction and wear experiments without lubrication. The results show that there are three sublayers on the alloy impregnation surface. The element content changes continuously in the impregnation layer. The impregnation layer is combined with the substrate by metallurgical bonding. Hardness of the alloy surface increases to HV0.11 200~ l 250. The transition layer connected to the substrate is of better strength and toughness ,which can effectively improve the wear resistance of the alloy.
