Abstract
The invention discloses a steel enameling method, comprising the steps of (1) performing mechanical polishing rust removing treatment on the surface of steel so as to make the surface of the steel clean; (2) soaking the treated steel in an aqueous solution of an oxidizing agent for 10-30 minutes; (3) taking out and airing the steel; (4) heating the steel under the natural environment, and immediately stopping heating the steel when the color of the steel starts turning blue; (5) cooling down the steel at room temperature, and then putting the cooled steel in an anti-rust oil to soak. The steel enameling method has the beneficial effects that the process operation is simple, the generated oxidized film is complete and uniform in thickness, the enameling process is quick, and the popularization is easy.
Description
Technical field
The present invention relates to a kind of steel part to give a protective coating to metal objects method.
Background technology
The corrosion thing on steel piece surface is a kind of material of crisp porous, can not protect inner layer metal iron not by corrosion.By chemistry or electrochemical treatment, can steel piece Surface Creation one deck be compact and complete and the process with the oxide film of certain physical strength is called the painted of iron and steel.Form certain thickness oxide film through the steel product surface of coloring treatment, present a kind of special oxidation tint---black-and-blue, be commonly referred to turning blue or turning black of steel piece.
The method of steel piece oxide treatment is a lot, has commutation oxidation style, alkali-free oxidation style, high-temperature gas oxidation style and point to separate oxidation style etc.
Turning blue of steel piece is usually used in the protected decoration of machinery, precision instrument, instrument, weapon, daily necessities etc., is specially adapted to not allow to electroplate or the part of japanning and the protection of Precision Machinery Elements that works in oil.
Traditional method of turning blue directly carries out heat treated to workpiece, make steel part complete the process of turning blue in atmosphere, metal oxide film can not control evenly, and effect of turning blue is bad, can not produce complete oxide film, the technology being therefore badly in need of a kind of improvement solves above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of steel part to give a protective coating to metal objects method.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of steel part gives a protective coating to metal objects method, comprises the following steps:
(1) mechanical grinding processing of rust removing is carried out to steel piece surface, make steel piece surface bright and clean;
(2) steel part handled well is put into aqueous oxidizing agent solution and soak 10-30 minute;
(3) steel part taking-up is dried;
(4) heating steel in physical environment, stops heating immediately when steel part color starts to change blueness into;
(5) naturally cooling steel part, is placed in slushing oil after cooling and is soaked.
In aqueous oxidizing agent solution, oxygenant is potassium permanganate, and potassium permanganate mass percent is in the solution 0.6-1.2%.
The temperature of heating steel is 350-450 degree Celsius.
The invention has the beneficial effects as follows: technological operation is simple, the oxide film of generation is complete and thickness is comparatively even, and process of turning blue is very fast, is easy to promote.
Embodiment
A kind of steel part gives a protective coating to metal objects method, comprises the following steps: (1) carries out mechanical grinding processing of rust removing to steel piece surface, makes steel piece surface bright and clean; (2) steel part handled well is put into aqueous oxidizing agent solution to soak 10 minutes; (3) steel part taking-up is dried; (4) heating steel in physical environment, stops heating immediately when steel part color starts to change blueness into; (5) naturally cooling steel part, is placed in slushing oil after cooling and is soaked.In aqueous oxidizing agent solution, oxygenant is potassium permanganate, and potassium permanganate mass percent is in the solution 0.6%.The temperature of heating steel is 450 degrees Celsius.Technological operation is simple, and the oxide film of generation is complete and thickness is comparatively even, and process of turning blue is very fast, is easy to promote.
