摘要（英）：

The invention discloses a surface treatment method of a cold rolled steel plate. The surface treatment method comprises the following steps of (1) cleaning the surface; (2) passivating for the first time; (3) modifying the surface; and (4) passivating for the secondary time. The surface treatment method has good popularization and application values, the processing step of surface passivation treatment of an existing steel plate is reasonably improved, the surface passivation treatment effect of the cold rolled steel plate is preferably increased, the corrosion and rust resistant capability of the cold rolled steel plate is increased, and the service life is prolonged.
