| 摘 要： | Influences of stabilizer (KI) on the corrosion performance of the Ni-Fe-P-B deposit alloys,were investigated using electrochemical methods,weightless corrosion and heat treatment.The results show that corrosion current density (0.1585mA·cm~(-2)),porosity(0.5 No.cm~(-2)) and weightless corrosion rate of the deposit (Ni-Fe-P-B) in corrosion media are lowest,when the stabilizer (KI) concentration is 8mg.L~(-1).Corrosion resistance of the deposit drops to a different degree in the range of 200℃～600℃,and slowly falls down when CKI=8mg.L~(-1).The lattice changes and diffusion layer forming of the deposit play important roles in the changes of corrosion performance in the different range of heat treatment.However,the hardness and abradability of testing alloy increase to a different degree in 200～400℃.When CKI=8mg.L~(-1),hardness of alloy is as high as 950HV after heat treatment at 400℃×1h,which is twice that of the as-plated coating.
