This patent discloses a method for preparing a high-hardness, smooth, and corrosion-resistant surface of ferrous metals. The metal sample to be treated is made into a friction pair. The material of the pair is the same as that of the metal sample to be processed and the hardness is similar. The initial surface roughness of the two pairs is Ra ≤1.6um, and lubricated by lubricating substances, which are lubricating oil, grease and emulsion containing serpentine, attapulgite, kaolinite, montmorillonite and other minerals, using splash lubrication and forced lubrication. The contact form of the friction pair includes surface-to-surface contact and line-to-surface contact. The friction form includes sliding friction and rolling friction. The cumulative friction movement time is not less than 72 hours. This process method is relatively simple, and one process section can realize "improving surface hardness, The comprehensive goal of "smoothness and corrosion resistance" has a certain promotion value.

The invention provides a base processing method, comprising the following steps: performing tempering treatment on the fins of the blank to obtain a first intermediate body with higher fin elasticity; performing first surface treatment on the fins of the first intermediate body And obtain the target workpiece with higher fin surface strength.
