摘    要：通过现代测试技术研究了不同成分电沉积Ni-Fe-P合金的结构、热稳定性、磁性和耐磨性。研究结果表明，Ni-Fe-P镀层中含磷量增大，镀层从晶态 晶+非晶态 非晶态，结构缺陷随之增多，表面圆顶状物尺寸变小；并且推迟了晶化稳定相的析出和再结晶，含铁量增大，镀层硬度，耐磨性和晶化温度均提高，Ni-Fe-P镀层的热稳定性和耐磨性优于Ni-P镀层。成分对Ni-Fe-P合金的磁性有明显的影响。

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.
