The corrosion resistance of metal-N double-element alternate implanted M50NiL bearing steel was investigated by potentiodynamic polarization and detection methods of SEM, XPS, AES and TEM. The results showed that ion implanted M50NiL can increase the corrosion potential of substrate, reduce the corrosion active points and inhibit the corrosion reaction induced at the grain boundaries. The formed amorphous layer and strengthening phases take main roles in improving the corrosion resistance of M50NiL bearing steel.

Silane Solution

Silane coupling agent is gradually concerns as a substitute for phosphate pre-treatment of painting. Ten kinds of silane solution such as the KH-450, KH-460, KH-470, KH-550, KH-560, KH-567, KH-578, 5501, 9810, BTSE were chosen as research objects in this paper. Corrosion resistance and adhesion of film were studied after silane treatment on A3 steel surface by copper sulfate drop test, alternate immersion in salt solution and adhesion experiments. These silane films were compared with uncoated A3 steel specimens. The results show that: silane treatment can improve the corrosion resistance of A3 steel in acid solution. KH-560, KH-5501 and KH-470 were ranked the top three in the corrosion resistance. KH-550, KH-560, KH-567 were fourth, fifth and sixth, respectively. Silane treatment can improve the corrosion resistance of A3 steel in neutral salt solution. KH-460, KH-560 and KH-567 have the best salt water corrosion resistance. KH-560 has better adhesion with paint film, following by KH-550 and KH460. When using ethanol and water as the hydrolysis solvent of silane, KH-450, KH-460, KH-470, KH-550, KH-560, KH-567, KH-578, 5501 have the better stability, but stability of 9810, BTSE are poor.

Phosphate Film

The silane films are fabricated by dipping cast aluminum alloy in silane solution, then curing films. The corrosion resistance of single silane film, composite silane film is compared with phosphating film through acid dropping test, salt water immersion test and electrochemical impedance test (EIS), the results shows that the silane films are obviously superior to the phosphating films in terms of the corrosion resistance of acid solution and neutral salt solution, particularly the corrosion resistance of composite silane films is much better than sigle silane films; corrosion polarization curves show that the corrosion tendency of KH550+KH567 composite silane film is minimum, corrosion rate is yet minimal, corrosion process of this silane films is controled by diffusion step. The corrosion process of uncoated aluminum substrate, KH550 silane films, phosphating films are controlled by electrochemical step. The impedance of phosphate films are lower than the silane films. Appropriate silane treatment can effectively improve adhesion between the coating and the Al substrate. The adhesion between silane film and paint film is firmer than the phosphate film, so silane film is an excellent replacement to phosphate film for painting pre-treatment.

Electrochemical Conversion

Chromium-free conversion coatings were generated to replace chromate chemical process by electrolysis treatment LY12 aluminum alloy in zirconate solution. Film thickness, dropping test, the adhesion between aluminum and paint film were tested for single-factor experiments and orthogonal to seek better electrolysis process. The paint adhesion is the first grade for electrochemical conversion solution containing complexing agents, or it is the second grade without complexing agents. When DNS complexing agent is 2 ~ 5g/L, film corrosion resistance rises with the increasing content of complexing agent. If voltage is too low, corrosion resistance of conversion coating is poor; voltage is too high, the films form powders. Better formulations for zirconate conversion coating are: 5g/L DNS complexing agent, 10V voltage, treatment temperature is 40°C. Electrochemical conversion coating is thinner than chemical conversion, but the corrosion resistance is better because the electrochemical conversion coatings are smoother and compacter than the chemical conversion coating. The paint films on electrochemical conversion coating are smoother than the chemical one. Two kinds of conversion coatings have very good adhesion with paint film up to the first level. Electrochemical conversion coatings thickness is 2.5 μm, bubble time of NaOH-glycerine solution on them is up to 92s.
