Preparation method of corrosion prevention plating coating

Abstract

The invention provides a preparation method of a corrosion prevention plating coating. The corrosion prevention plating coating which can protect a high-strength material against hydrogen brittlenessand solve the problem of contact corrosion between the high-strength material and nonferrous metals and has different appearance colors can be prepared through the vacuum ion plating technology, the shot blasting technology, the chemical conversion technology and the hydrophobic treatment technology. The preparation method is used for solving the problems of hydrogen brittleness of the high-strength material in aerospace parts and other weaponry parts and contact corrosion between the high-strength material and the nonferrous metals. Through the preparation method, the surfaces of the parts are protected through ion plating aluminum, shot blasting, chemical conversion and hydrophobic treatment to meet the protection requirements. The corrosion prevention plating coating which can protect the high-strength material against hydrogen brittleness and solve the problem of contact corrosion between the high-strength material and nonferrous metals different appearance colors and has differentappearance colors are prepared so as to solve the problems of hydrogen brittleness of the high-strength material in the aerospace parts and other weaponry parts and contact corrosion between the high-strength material and the nonferrous metals.

Description

technical field [0001] The invention relates to the field of anti-corrosion, in particular to a method for preparing an anti-corrosion coating with a protection time of more than 700 hours. Background technique [0002] With the continuous improvement of the performance of today's weapons and equipment, high-strength materials and non-ferrous metals have been widely used in weapons and equipment. Traditional protection technologies have highlighted more and more problems, such as hydrogen embrittlement, cadmium embrittlement, zinc embrittlement, potential poor corrosion etc. [0003] Fasteners are common basic parts widely used in aviation products, such as bolts, nuts, screw sleeves, etc. The quality of fasteners plays an important role in the working performance and structural safety of engineering equipment, and its reliable connection is related to the quality of equipment. Reliability is also related to the overall safety of engineering equipment. Many fasteners expose...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the deficiencies in the prior art that the hardness of the material will be reduced when the deposition temperature is high, and the protective treatment of the parts without the aluminum coating layer is not considered for complex parts, the present invention proposes a method for preparing an anti-corrosion coating
