Anti-corrosion and anti-rust treatment process and anti-corrosion and anti-rust coating on iron-based material

Abstract

The invention discloses an anti-corrosion and anti-rust treatment process and an anti-corrosion and anti-rust coating on an iron-based material. The anti-corrosion and anti-rust treatment process comprises the following steps that (1) surface pretreatment of polishing or grinding treatment is carried out on the iron-based material; (2) ultrasonic wax removal, oil removal cleaning and drying are carried out after the step (1); (3) after the step (2), the treated iron-based material is hung on a hanging tool; (4) the iron-based material in the step (3) is put into a vacuum chamber of a vacuum coating machine to be subjected to ion glow activation, and a bottoming metal layer, a silicon-chromium alloy layer, a complexion chromium coating and a protective layer are sequentially deposited on the surface of the iron-based material in a physical vapor deposition mode; and (5) the iron-based material obtained in the step (4) is taken out of the vacuum coating machine. The process is low in cost and convenient to treat, large-area application and popularization are facilitated, meanwhile, a large amount of water pollution and poisonous and harmful gas emission cannot be caused, and the requirement for national economic development in the future is met.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion treatment of iron-based materials, in particular to an anti-corrosion and anti-rust treatment process and an anti-corrosion and anti-rust coating on iron-based materials. Background technique [0002] It is known that metal iron is widely used in industrial production and life because of its low price and excellent performance, but because of its active chemical properties, it is prone to rust during use, seriously affecting the appearance and function of the product, and greatly reducing the product quality. service life. [0003] The main protection method currently used is to prevent corrosion of iron-based metal materials through alloying or surface treatment. [0004] For example, surface treatment is a widely used iron-based antirust method at present, and surface coating and electroplating are relatively common processes. Anticorrosion of the base material is achieved by coating a ...
