Abstract

The invention provides a method for treating a steel-based surface of a nanocomposite material. The method comprises the following treatment steps of 1, sequentially carrying out ultrasonic cleaning,drying, alkali treatment, acid treatment, water washing and drying treatment on a steel plate; 2, sequentially carrying out high-energy shot blasting, water washing and drying treatment on the steel treated in the step 1; and 3, sequentially carrying out ultrasonic punch impact treatment on the steel substrate treated in the step 2. The method for treating the steel-based surface of the nanocomposite material has the beneficial technical effects that the comprehensive performance can be greatly improved and the service life can be greatly prolonged; and the surface treatment method is simple in process, low in cost and suitable for large-scale production and application.

Description

technical field [0001] The invention relates to a nanocomposite material steel base surface treatment method, which belongs to the field of material surface treatment. Background technique [0002] When composite parts are in use, fatigue, wear and corrosion often occur, resulting in damage and failure of the parts. Therefore, in order to improve the performance of composite parts, strengthening the surface of metal materials is the most effective method. Because of its own structural characteristics, nanocrystals have very good mechanical, physical and chemical properties. By using nanotechnology to improve the surface of traditional composite materials, the comprehensive performance and service life of these traditional composite materials can be well improved. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems of the prior art, provide a surface treatment method with simple process, low cost, and suitabl...
