| Abstract: | ZrO2 and 40Cr steel were brazed by inserting buffer Ni,4J33,Ti and Cu separately. The chemical composition of 4J33 and Ni will damage the wetting property of Ag66Cu30Ti4 filler metal to ceramic and hinder the interface reaction between the active filler metal and Zr O2, so ZrO2/40Cr steel can not be bonded. Cu and Ti can efficiently release the residual stresses in the ceramic without injuring the wettabilty of filler metal, so the high joining strength can be obtained by inserting Cu and Ti. |
