Abstract

The invention provides a base material with high surface binding force and a preparation method thereof. The preparation method comprises the following steps of testing the diameter and depth of a micro-pit on the base material after a single pulse reacts with a material by using pulse laser. By changing the power or the number of machining times, a relation curve between the single-pulse energy and the number of machining times and the size and depth of the micro-pit can be obtained, and in practical application, a certain machining path and a certain scanning speed can be rapidly set for machining according to the relation curve and the size of the needed micro-pit, and thus, a high-binding-force base material with micro-pits regularly arranged and non-overlapped on the surface of the base material. According to the method, the roughness, the binding force and the variable surface tension (hydrophilic-hydrophobic property) of the surface of the base material can be remarkably improved. The preparation method is particularly suitable for a hydrophobic substrate, and the hydrophilicity of the hydrophobic substrate is remarkably improved after laser processing, so that the deposition speed of the hydrophobic substrate in an aqueous solution can be increased, the wettability can be improved, and the deposition speed of the material can be increased.

Description

technical field

[0001] The invention relates to the technical field of surface processing, in particular to a base material with high surface binding force and a preparation method thereof. Background technique

[0002] In industrial manufacturing, it is widely used to compound another material on one material. The performance of the resulting composite material is highly dependent on the bonding force between the two materials. Therefore, in industry, the bonding force is an important factor for materials. parameter.

[0003] Mechanical method or chemical method is currently the most commonly used method to improve the bonding force. It roughens the surface of the workpiece through mechanical wear or chemical corrosion to obtain a microscopic rough structure on the surface of the workpiece. This roughening increases the contact area between the two materials while increasing the peel strength between the two, thereby improving the bond. However, these methods have many di...
