Effect of Interlayer on Interfacial Bonding Properties of Stainless Clad Sheets

In view of the features of diffusion welding process, some interlayer materials were used to facilitate the stainless steel sheet to clad the carbon-steel sheet. A series of tests were done to investigate various influential factors on cladding process, such as pressure, temperature, holding time and protective gas. It is found that some interlayer materials can provide optimum technological parameters to cladding process. The stainless steel sheet can be clad onto carbon-steel sheet if taking silver-copper-zinc solder as interlayer or sandwiched layer for cladding at 750°C with 25% reduction in first pass. Pure argon has proved that it is an effective protective gas from surface oxidation. In addition, the influence of various parameters on cladding results was also analyzed theoretically.
