Abstract :
This article describes a study of the application of a roll bonding technique to MS90(CuZn 10) alloy strips and steel sheets using a chromized interlayer. It was found that the overall bond between these two metals resulted from two different types of bonds: a block bond, linking the MS90 alloy strips and chromium topcoat layer, and a blank bond, linking the MS90 alloy strips and bare steel surface in the area where the chromium coating has been fragmented. This study investigated the effects of plating time on the thickness of the coating layers and of the area fraction of the blank bond on the bond strength. The overall bond strength depends mainly on the strength and the area fraction of the blank bond. A linear relationship model exists between the overall bond strength and the area fract ion of the blank bond . The bond strength of the blank bond was eight times greater than that of the block bond . The area fraction of the blank bond increased with increasing the coating thickness up to 55 (mu)n, but thereafter decreased due to the rotation of the chromium blocks.
