Description
Technical field:
The present invention relates to a kind of methods of automobile cylinder cap surface preservative treatment, belong to field of metal surface treatment technology.
Background technique:
Surface treatment is that one layer of table different from the machinery of matrix, physical and chemical properties is artificially formed on substrate material surface
The process of layer.The purpose of surface treatment is the corrosion resistance for meeting product, wearability, decoration or other features requirements.
For metal casting, our more commonly used surface treatment methods are mechanical grindings, chemical treatment, and Surface heat-treatent sprays table
Face, surface treatment be exactly workpiece surface is cleaned, is cleaned, deburring, degreasing, descale etc..
Blackening process is that steel is heated in air or is directly dipped in dense oxidizing solution, generates its surface very thin
The material protection technology of oxidation film.Solution composition, reaction temperature and time when nigrescence is depending on the ingredient of steel substrate.Hair
The ingredient of black film is magnetic iron oxide, and with a thickness of 0.5~1.5 micron, color is related with material composition and process conditions, there is ash
Black, pitch black, brilliant blue etc..Individual black film corrosion resistance is poor.
During use, anti-icing fluid can be mixed generation chemical reaction to automobile by some car owners, and cylinder cap is caused to be corroded.
It will lead to running car inability after automobile cylinder cover corrosion, the bad phenomenons such as engine shake occur, and have seriously affected garage
The safety sailed.
Summary of the invention:
The purpose of the present invention is providing a kind of method of automobile cylinder cap surface preservative treatment in view of the above problems, pass through
It after preservative treatment, can effectively avoid automobile cylinder lid from corroding, improve the safety that automobile uses.
Above-mentioned purpose is realized by following technical scheme:
The method of automobile cylinder cap surface preservative treatment, this method comprises the following steps:
(1) pickling is carried out to automobile cylinder lid；
(2) the automobile cylinder lid after pickling is washed and is dried；
(3) configuration blackening solution carries out blackening process: the blackening solution includes copper sulphate, selenium dioxide, nickel sulfate, nitric acid
