Abstract
The invention provides an oxidation process for the surface of a steel part. The oxidation process includes the following steps that (1) mechanical grinding and derusting are conducted on the surface of the steel part; (2) sand blasting is conducted on the steel part; (3) shot blasting is conducted on the steel part; (4) the surface of the steel part is cleaned; (5) the treated steel part is placed in an oxidizing agent water solution to be immersed for 10-30 minutes; (6) the steel part is taken out and aired; (7) the steel part is heated in a natural environment, and the steel part stops being heated immediately when the steel part begins to turn blue; and (8) the steel part is naturally cooled, and the steel part is placed in anti-rust oil to be immersed after being cooled. The oxidation process has the beneficial effects that the process operation is simple, and a generated oxidation film is complete and uniform in thickness; the blueing process is quick, and popularization is easy.
Description
Technical field
The present invention relates to a kind of steel piece surface oxidizing process.
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 piece surface oxidizing process.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of steel piece surface oxidizing process, comprises the following steps:
(1) mechanical grinding processing of rust removing is carried out to steel piece surface;
(2) sandblasting is carried out to steel part;
(3) shot peening is carried out to steel part;
(4) steel piece surface is cleared up;
(5) steel part handled well is put into aqueous oxidizing agent solution and soak 10-30 minute;
(6) steel part taking-up is dried;
(7) heating steel in physical environment, stops heating immediately when steel part color starts to change blueness into;
(8) 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 5-10%.
The temperature of heating steel is 500-600 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
