No.4（2001）1.Microstructure and magnetic property of electrodeposited Ni-P alloy film

Kiyoshi ITOH, Feng WANG and Tohru WATANABE

The electrodeposited Ni-P alloy films were obtained from Watts baths containing H3PO3. The crystallographic structure and morphology of electrodeposited Ni-P films were studied by using XRD, SEM and Vibrating Sample Magnetometer. The X-ray diffraction patterns of Ni-P electrodeposited films with various P contents gradually changed from sharp peaks to broad peaks with increasing P content in the electrodeposited films. SEM images of low NiP films at high P content were flat and ductile, otherwise those at low P content were brittle. Films at low P content had high magnetic force, residual magnetization, and saturated magnetization. Otherwise, films at high P content had no magnetic properties.
