The purpose of this study makes use of infrared repair brazing with the characteristic of rapid heating 410 stainless steel by a nickel base brazing filler. Both L.M. nickel base filler and 410 stainless steels are rich in chromium, and Cr(subscript x)B(subscript y) precipitates are found in the joint after brazing. With ever increasing brazing temperature or brazing time, the phase is gradually stabilized. FeNi3 phase was found in SEM observations. The FeNi3 phase shows two different colors, gray and white, due to different Si content in FeNi3, and it converts into single color as increasing brazing temperature and time. In additions, a layer of Fe-Cr-(B) alloy was found at the joined interface. The mechanical property of the nickel base filler, e.g. hardness and wear resistance, demonstrates better performance than that of 410 stainless steel.
