Abstract The effect of rare earth addition to brush plating bath on structure and corrosion resistance of electrodenosited Ni－P alloy layer was studied．The results showed that the addition of 1g／L of blent rare earth could promote non-crystallization of the resulting Ni－P（RE）alloy layer，which was amorphous with even as low as only 5％ P．The Ni-P (RE) alloy had higher corrosion resistance than Ni-P alloy without rare earth in 3．6％ HCl solution and sea water．A mechanism of improvement was proposed．The rare earth ions might be adsorbed on the eledrode surface and interfered with normal discharge and diffusion of Ni2+ so as to promote the non-crystallization.
