Method for enhancing corrosion resistance of joint between pure Ti/Ti-base alloy and Fe-base steel alloy using Ag-Cu-Pd inserted material and Ag diffusion control layer
Method for enhancing corrosion resistance of joint between pure Ti/Ti-base alloy and Fe-base steel alloy using Ag-Cu-Pd inserted material and Ag diffusion control layer
The present invention comprises the steps of forming a silver diffusion control layer on a titanium or titanium alloy base material (step 1); Placing a silver-copper-palladium insert between the titanium or titanium alloy base material on which the silver diffusion control layer is formed and the steel-based alloy in step 1 (step 2); And a titanium using a silver diffusion control layer and a silver-copper-palladium insert, comprising the step (3) of joining the titanium or titanium alloy base material and the steel-based alloy by heating above the melting temperature of the insert inserted in step 2. Or it relates to a method of improving the corrosion resistance of the joint between the titanium-based alloy and the steel-based alloy, the method according to the invention by forming a silver diffusion control layer on the titanium base material, by inserting a silver-copper-palladium insert having a specific composition ratio It is useful for dissimilar brazing bonding between titanium or titanium-based alloys and steel-based alloys, as it does not reduce the mechanical properties of dissimilar metal joints and improves seawater corrosion resistance of dissimilar metal joints. Can be used.;Silver Diffusion Control Layer, Silver-Copper-Palladium Insert, Titanium, Joints, Steel, Sea Water, Corrosion Resistance
