Other AbstractIn this investigation, dense and defect-free specimens of single-track were fabricated at high deposition rate and the 316L stainless steel powers were used as deposition material. The influences of the vibration of deposition current, traverse speed, powder feeding rate on the values of the height, width and depositing angle of the specimens were studied, moreover, the microstructure and composition of the deposited samples were examined and analyzed. The results indicated that, the depositing angle increases with the increasing of powder feeding rate and decreases with the increasing of deposition current. The depositing angle of specimens fabricated under different deposition parameters are mainly sharp angles, which is beneficial for the deposition of lapped samples. Among all the process parameters, the width of the single tracks is mostly affected by the deposition current, while the height of the single tracks is mostly affected by the traverse speed. The dilution rate decreases under lower scanning speed, lower powder feeding rate or higher deposition current. The composition distribution of the single tracks is uniform, and the solidified microstructure is composed of austenite and ferrite phase.
