Problems solved by technology

Heavy hammers are mostly cast from raw materials such as cast iron. In order to improve the quality and life of heavy hammers, the surface of heavy hammers is usually modified. Due to the presence of moisture in the external environment, corrosion problems have always occurred, while cast iron Long-term corrosion of parts will cause a decrease in mechanical strength, concentration of stress, and even the risk of fracture, which will affect the overall stability of use
In the prior art, the performance of this type of coating is often relatively single, the overall performance is not good, and its bonding strength with the substrate is not high, so continuous improvement and optimization are required

Abstract

The invention discloses a surface enhancement treatment method for a heavy hammer sheet. The method comprises the following steps of (1) surface cleaning treatment; (2) shot blasting treatment; (3) surface plasma treatment; and (4) coating spraying and covering treatment. According to the surface enhancement treatment method for the heavy hammer sheet, the surface enhancement treatment method forthe heavy hammer sheet is simple in overall process and easy to popularize and apply, the treated heavy hammer sheet has the advantages that the mechanical property is good, the corrosion resistance is high, the anti-aging capability is strong, the coating stability is high, and the comprehensive service life is remarkably prolonged.

Description

technical field [0001] The invention belongs to the technical field of heavy hammer sheet processing, and in particular relates to a surface strengthening treatment method for heavy hammer sheets. Background technique [0002] In recent years, with the extensive application of composite insulators for overhead transmission lines, especially the suspension strings of diversion wires for tension poles and towers, composite insulators are light in weight and poor in wind deflection resistance, and wind deflection discharge accidents are prone to occur, so it is necessary to install heavy hammers to Improve the wind resistance of transmission lines. Heavy hammers are mostly cast from raw materials such as cast iron. In order to improve the quality and life of heavy hammers, the surface of heavy hammers is usually modified. Due to the presence of moisture in the external environment, corrosion problems have always occurred, while cast iron Long-term corrosion of components will ...
