In order to produce diffusion-rolling sandwich panels under small reduction, a bonding assistant coat which mainly contains Cu, Zn, Mn and small amount of Si, Sn, Ni, B and rare earth elements was designed for carbon steel plates at 850℃.

One of the problems experienced in transient liquid diffusion bonding for carbon steel sandwich panels is the interlayer bonding assistant coat.

Investigation has been carried out on the interface bonding strength of Cu/Mo/Cu composite sheets produced by room temperature rolling with a reagent coat.

The technique of adding reagent coat is put forward for improving composition condition, because of the oversized mill load caus.
