Problems solved by technology

[0004] The commonly used bonding technology of titanium and titanium alloys and plastics is hot-melt adhesive method, but the bonding strength is low and the reliability is poor.
There is also a combination of electrochemical film formation and injection molding. Although the bonding strength is high, the electrolyte used is mainly fluoride or chromate, which is highly toxic, seriously pollutes the environment, and has a high risk factor for personal safety.
Therefore, the application of both binding methods is limited

Embodiment Construction

[0011] The present invention will be described in further detail below.

[0012] The embodiment of the present invention provides a method for manufacturing a titanium alloy-plastic composite. Including the following steps:

[0013] In the first step, a titanium alloy substrate is provided, and the titanium alloy substrate is degreased and deoiled.

[0014] The titanium alloy substrate is degreased and degreased according to a common method, and then the surface of the titanium alloy substrate is washed with water.

[0015] The second step is to perform activation treatment on the titanium alloy substrate after degreasing and degreasing.

[0016] Specifically, after the titanium alloy substrate is degreased and degreased, it is soaked in 1-10 wt% dilute sulfuric acid or salt solution for 1-60 minutes. Then wash with deionized water to make the surface of the titanium alloy substrate clean.

[0017] In the third step, the surface of the titanium alloy is etched through a su...

Abstract

The invention provides a manufacturing method of a titanium alloy-plastic complex. The manufacturing method comprises the following steps that a titanium alloy substrate is provided; etching is conducted, so that the surface morphology that micrometer grooves are combined with nanometer holes is formed on the surface of the titanium alloy substrate; plastic is injected into the surface, with the surface morphology that the micrometer grooves are combined with the nanometer holes, of the titanium alloy substrate, and the titanium alloy-plastic complex is obtained.

Description

technical field [0001] The invention relates to a method for manufacturing a titanium alloy-plastic composite body. Background technique [0002] Titanium and titanium alloys have good mechanical properties and mechanical properties, excellent physical and chemical properties, such as low density, high specific strength, high corrosion resistance, insect magnetism, high hanging resistance, etc., as well as excellent casting properties. It was first used in industrial production such as aerospace, aviation, petroleum, seawater desalination and daily life appliances. [0003] In recent years, under the guidance of the trend of 3C products being "thin, thin and small", personalization and novelty, the development of product casing and internal component materials is increasingly inclined to use titanium and titanium alloys, and the use of titanium and titanium alloys and dissimilar materials (such as engineering plastics) to learn from each other. It not only utilizes the hig...
