Problems solved by technology

[0002] At present, in the production of metal products in our country, in order to enhance the surface hardness and corrosion resistance of metal products, the process of plating hard chromium on the surface of metal products is generally used. The disadvantages are low hardness, poor wear resistance and corrosion resistance, and easy carbon deposition. Difficult to clean, high waste silk rate
Especially for high-strength industrial yarn, the existing technology can no longer meet the demand

Embodiment 1

[0021] A method for coating a metal product surface, characterized in that it comprises the following steps:

[0022] (1) Cleaning and shot blasting surface treatment of metal product blanks;

[0023] (2) Dye the cleaned and shot-peened surface-treated metal product blanks and then wire-draw them to draw out the desired texture;

[0024] (3) Cleaning and activating the surface of the metal product blank treated in step (2); evaporating and ionizing the cathode through an electric arc to generate plasma;

[0025] (4) The plasma is reacted with the charged reaction gas in the vacuum chamber, and the reactant is deposited on the surface of the metal product blank to be plated by plasma spraying.

[0026] The metal product is selected from one of iron, aluminum alloy, magnesium alloy, zinc alloy and copper alloy.

[0027] The concrete method of described dry cleaning is as follows:

[0028] First wipe the surface of the metal product with a dry cloth to remove grease and dust, ...

Abstract

The invention provides a metal product surface film plating method. The metal product surface film plating method comprises the following steps: (1) the cleaning and the shot blasting surface treatment are performed on a metal product blank; (2) the wire drawing is performed on the metal product blank to draw out needed lines after the cleaning, the shot blasting surface treatment and the metal blackening; (3) the surface cleaning and the activation are performed on the metal product blank after treatment in the step (2); and a cathode is evaporated and ionized to generate plasma through arc; and (4) the plasma is reacted with filled reaction gas in a vacuum chamber; and reactants are deposited on the surface of the metal product blank to be plated through plasma spraying. Film plating products are excellent in functions and appearances and suitable for such industries as electronics, household appliances and vehicles, and deserve popularization and application.

Description

technical field [0001] The invention relates to the technical field of metal products, in particular to a method for coating the surface of metal products. Background technique [0002] At present, in the production of metal products in our country, in order to enhance the surface hardness and corrosion resistance of metal products, the process of plating hard chromium on the surface of metal products is generally used. The disadvantages are low hardness, poor wear resistance and corrosion resistance, and easy carbon deposition. It is not easy to clean, and the waste silk rate is high. Especially for high-strength industrial yarn, the existing technology can no longer meet the demand. The surface hardness of hard chrome is HV850-1100, and the friction coefficient is 0.16-0.17. When the temperature reaches 80°C, the surface hardness begins to decrease. The higher the temperature, the lower the hardness, and the decrease can reach up to 50%. Contents of the invention [00...
