摘要：

The phi -pH diagram of Ni-B-H2O system was drawn, and the mechanism of electrodepositing Ni-B-SiC composite coatings was discussed. The results show that the deposition of Ni and B occurs prior to that of H-2 because of the over-potential of H-2 evolution on the Fe substrate. Boron can not singly deposit in aqueous solution. Nickel and boron can co-deposit in the form of Ni4B3 without evolution of hydrogen when the cathodical potential is kept to be -1.415 similar to -1.700 V.
