Abstract
The reason and improvement method of poor conjunction of chemical electronickelling for welded combined parts of magnetic DT4C and stainless steel 1Cr18Ni9Ti were studied.The method to remove welding oxide skin was determined.By pre-electronickelling,i.e.,electroless nickel-plating on products,nickel plate which had good bonding force and uniform thickness,and no effect on magnetic properties of parts including coercive force Hc,magnetic induction strength B500 and maximum permeability was obtained.
