Özet
Pure titanium alloys are frequently used in the aviation, space, and marine industries due to their low heat conduction, high formability, and superior corrosion resistance. In this study, a hybrid manufacturing process for pure titanium was carried out in which substrate and deposition were combined using Plasma-WAAM. The microstructure analysis, microhardness, tensile and wear properties were investigated for the substrate, interlayer and deposited regions. In addition, the anisotropy of the tensile properties in the deposition and interlayer areas was examined. The microstructure analysis of samples showed an equiaxed α phase in the substrate and acicular α phase in the interlayer region. Columnar α was observed in the down region, whereas equiaxed + columnar α phases were observed both middle and up regions of deposition. The average hardness value of substrate sample (SS) is 170.9 HV and go up on deposition region this value is approximately 80% increased. The results of tensile tests show that the ultimate tensile strength (UTS) is increased by 75% for the horizontal interlayer sample (INS-H), decreased by 15% for the vertical interlayer sample (INS-V) and increased by 35 and 80% for horizontal (DS-H) and vertical deposition samples (DS-V) respectively, compared to the wrought manufactured substrate sample (SS). The results for the wear properties indicated that the specific wear rates did not vary for the substrate, interlayer, and deposition areas.
