When the marine stainless steel is used in the parts such as a crude oil tank, one side of the stainless steel is used as crude oil, coating is not needed, the other side of the stainless steel is used as a ballast tank, the stainless steel is directly contacted with the seawater environment, and chloride ions in the seawater can damage a passivation film of the stainless steel to cause pitting corrosion perforation, so that the stainless steel on one side needs to be subjected to corrosion-resistant coating operation.
According to the prior art, the Chinese patent documents CN 111001989A, CN 111002162A and CN 110976252A both provide surface treatment process methods for stainless steel materials, but the methods aim to improve the welding, processing and other performances of the stainless steel materials, and do not relate to treatment measures for corrosion protection in seawater environment.

in the step (4), the coating is to coat primer on the surface of the stainless steel, and the construction mode is one or more than two of spraying, brushing, roller coating and dip coating;
in the step (5), externally applied micro-current is adopted to accelerate the reaction of the stainless steel surface and oxygen to form a passivation layer, the voltage of the micro-current is-0.8V to-1.2V relative to the saturated calomel electrode, the current is 0.01-0.5A, and the passivation time of the micro-current is 5-30 min.
