The steel is subjected to the cathodic electrolysis treatment for 1-30min electrolysis time at 0.1-10A/dm<2> current density. The corrosion preventive film consisting of the intricate hydrate of various metallic ions contained in the electrolyte is formed on the steel surface by such treatment, ...
About anti-corrosion treatment防腐等级分类 Regarding the anti-corrosion treatment, there are two widely used and accepted standards in the industry, i.e., ISO12944 and ASTM B117. Among them, ISO12944 is the international standard, which is basically the gold standard of the whole industry; ASTM...
Conventional surface hardening methods for austenitic stainless steel in general lead to a reduction of the corrosion resistance and/or changes in shape/size. Hardcor is a surface hardening treatment that improves both the wear and corrosion resistance of austenitic stainless steel components, without ...

coatings.The corrosion behaviour of coated carbon steel has been evaluated bypotentiodynamic polarization and electrochemical impedance spectroscopy methods. Results show that the highest corrosion resistance of the coated substrate by the Ni‒P nano-structured coatingis achieved after heat treatment at ...
