Abstract:The structure and properties of the electrodeposited Ni-Fe-P alloys with various compositions were studied by modern testing method. The results showed that the deposit would be from crystalline→crystalline+amorphous→amorphous, the structure defect increased and the granular convexities on the deposit surface decreased with the increase of P content, which deferred the emergence and recrystallization of stable phases. The microhardness, wear resistance and thermostability increased with Fe content.The thermostability and wear resistance of the amorphous Ni-Fe-P were superior to the amorphous Ni-P alloy.The composition of Ni-Fe-P coating had an obvious influence on its magnetic properties.
