The 316 stainless steel-alumina joining was prepared by a modified moly-manganese (Mo-Mn) process and a Ni net-embedded brazing method. The modified Mo-Mn process had a reaction layer between the Mo-Mn layer and the alumina substrate, followed by brazing with steel. The reaction products of the reaction layer with substrate and the Mo-Mn layer were investigated. The brazing method had a braze foil/compressed Ni net/braze foil set sandwiched between steel and alumina. The reactions among the Ni net, braze alloys and substrates were studied.
