Abstract
Electrodeposition experiments of gradually composite alloys were conducted using rotating disc geometry. Effects of rotating speed and potential on the composition of alloys were studied. Mechanical properties and corrosion resistance of the gradually composite alloys were compared with those of the normally deposited alloys. Zinc content of Zn-Ni alloys increased as increasing disc rotation speed and voltage. However, Zn content of Zn-Ni-P alloys decreased but those of Ni and P increased as raising voltage. Zinc content of Zn-Fe and Zn-Fe-P alloys increased as raising voltage, however, Zn, Fe and P contents were not changed as increasing disc rotation speed. Corrosion resistance and adhesion of the gradually composite alloys for all the tested alloys were better than the normally deposited ones.
