Abstract TiN multi-permeated layers were formed on the steel surface with diffusion layer and deposition layer by means of both double glow-discharge surface alloying process and reactive sputtering.The surface appearances and composition and its corrosion-resistance in 10% H2SO4 and 3.5% NaCl of TiN multi-permeated layers by using different processes were investigated.The results indicated that the TiN multi-permeated layer was uniform and compact,th
e content of atom Ti,N gradually decreased with increasing distance from the surface.The adhesion of the TiN coating was very strong,its thickness was more than 10 μm.The corrosion resistance of the TiN multi-permeated layer in 10% H2SO4 and 3.5% NaCl was excellent,the corrosion rate was only 0.156 g/(m2·h) and 0.025 g/(m2·),respectively.
