| Abstract Scope |
Additive friction stir deposition (AFSD) has successfully manufactured large metallic components utilizing a variety of materials, including aluminum alloys, magnesium alloys, Inconel and stainless steels in the last decade. The promising development of AFSD promoted the application of AFSD as a surface repairing technique to structurally restore the damaged surface from corrosion and wear. In this research, pre-grooved substrates were repaired with the same feedstock material using the AFSD. The mechanical property and the microstructure in the repaired deposit and pre-grooved substrates were revealed from microhardness, three-point bend test, quasi-static tensile tests, and electron backscattered diffraction. AFSD has successfully repaired steels and aluminum alloys, with a dense deposit filling the groove without any observable pores from the micrographs. The thermal cycles from the AFSD process resulted in a heat-affected zone with lower mechanical strength in the pre-grooved substrate. The deposited stainless steel exhibited wrought-like mechanical properties. |
