Microstructure design of C/C composites through electrochemical corrosion for brazing to Nb
文献摘要：
Surface structure of C/C composites has been regulated through electrochemical corrosion at room tem-perature to modify the residual stress and improve the joining strength when brazed to Nb.The unique crevice corrosion in C/C composites is investigated to reveal the change of corrosion depth and fiber size.The interlacing zone of carbon fiber reinforced brazing alloy replaces the reaction layer in the original joint.Joining area is increased dramatically and the continuous crack will be hindered.The interlacing zone eliminates the stress concentration and relieves the residual stress through reducing the property mismatch.All advantages contribute to the joining quality of C/C-Nb.Shear strength of C/C-Nb joint with 80 μm depth reached 37.7 MPa,which was 1.2 times higher than that of original joint.Surface structure design of C/C composites not only expands the application in structure component,but also exhibits the promising application in energy field.
