Preparation method of Fe-FeB deposition layer on surface of low-carbon steel

Abstract

The invention discloses a preparation method of a Fe-FeB deposition layer on the surface of low-carbon steel. The preparation method comprises the steps that (1) a plating solution is prepared, specifically, a surface active agent CTAB is stirred and dissolved, other components are added and stirred evenly, pH is adjusted to be 2.5-3.5 through dilute ammonia water and diluted hydrochloric acid, and finally the plating solution is subjected to ultrasonic dispersion for 25-30 minutes; (2) the surface of the low-carbon steel is treated, specifically, the surface is ground to remove oxide and burrs on the surface layer, degreasing and cleaning are conducted through acetone to remove oil stains, and then the surface is cleaned through deionized water and ultrasonically cleaned through absolute ethyl alcohol; (3) the Fe-FeB deposition layer is prepared on the surface of the low-carbon steel through an electro-deposition method, and the electroplating process meets the conditions that the cathode-current density is 3-4 A / dm<2>, the temperature is 35-45 DEG C, and the stirring speed is 200-300 rpm; and (4) thermal treatment is conducted on the low-carbon steel after the deposition layer is electroplated. By means of the method, the deposition layer with high hardness, abrasion resistance, corrosion resistance and physical and chemical stability can be obtained on the surface of the low-carbon steel.

Description

technical field [0001] The application relates to a method for preparing a Fe-FeB deposition layer on the surface of low-carbon steel. Background technique [0002] As an important functional structural material, low carbon steel is widely used in chemical industry, metallurgy, electronic information and other fields. However, its surface is soft and has high activity, which makes it difficult for low carbon steel to meet some specific requirements, so it is urgent to improve its surface properties. [0003] Surface treatment of metal materials is a process of artificially forming a surface layer with different physical and chemical properties from the substrate on the surface of the metal material. It is the most economical and effective way to design and modify the surface of the material and the substrate as a unified system. The method improves the morphology, chemical cost, and organizational structure of the material surface and the surface area, and endows the materi...
