【 摘 要 】

Ni-P coatings were prepared on carbon steel in ammonia-citrate bath by pulse electrodeposition. The effect of pulse duty cycle on the microstructure, wear, corrosion and tribocorrosion resistance of Ni-P coatings were investigated systematically. The results showed that pulse duty cycle has less effect on the microstructure of the Ni-P coatings. However, the Ni-P coating prepared under 50% duty cycle exhibited superior wear, corrosion and tribocorrosion resistance. In addition, the corrosion plays a leading role in tribocorrosion process.
