Abstract :
The electrodeposited nanocrystalline by nano-plating technology is used in electronic components and have more excellent properties in tribological property and service life. In this paper the electrodeposited nanocrystalline of Ni-Co alloy nano-plating technology is introduced and the influence of pulse frequency on micro-hardness, internal stress and micro-morphology of high frequency pulse electroplating Ni-Co composite coating is studied. The results show that as the frequency increased, the surface of the plating tended to be more compact and internal stress of the plating is lower. As surfactant, sodium allylsulfonate, saccharin sodium and thiourea improve the micro-hardness evidently and thiourea is the best one of them, reached 526 HV.
