Abstract
The invention provides a surface treatment method of magnesium and magnesium alloy. The invention belongs to the technical field of metal treatment. The method comprises steps of a degreasing treatment step and a chemical treatment step. The degreasing treatment step comprises processes that: a magnesium or magnesium alloy object is wiped by using degreased cotton dipped with a solvent A; when oil stain is removed, the object is wiped 2-4 times by using clean cotton cloth. The chemical treatment step comprises processes that: the magnesium or magnesium alloy object is immersed in a solvent B for 10min under a temperature of 30-70 DEG C; the object is washed by using water, and is immersed in the solvent B for 5min under a temperature of 40-55 DEG C; the object is washed by using distilled water, and is dried under a temperature below 60 DEG C. The method is advantaged in wide application range, no toxicity, no odor, no three waste discharging, no harm to human bodies, no pollution to the environment, simple technology, no peeling, and no scaling. With the method, the treated object is advantaged in good appearance and long service life.
Description
Technical field
The present invention proposes a kind of magnesium and surface treatment method of Mg alloy, belongs to the metal treatment technical field.
Background technology
The metallic surface inevitably can be oxidized in various thermal treatments, mechanical workout, transportation and keeping process, produces the zone of oxidation of one deck became uneven.Simultaneously, also receive the impurity of various pollution by oils and absorption some other easily.Greasy dirt and some adsorptive, thin zone of oxidation can be successively with solvent cleaning, chemical treatment and treat mechanicallys, or directly use chemical treatment.For the highly oxidized metallic surface, zone of oxidation is thicker, just can not be directly with solvent cleaning and chemical treatment, and preferably carry out treat mechanically earlier.Common metallic surface after treatment has high activity, receives the pollution of dust, moisture etc. more easily once again.Along with the development all trades and professions in market are all constantly making new advances; Surface treatment is the demand that the traditional plating pattern in market of a new needs developing can not satisfy people day by day; Particularly human body is not constituted harm, the environmental protection method that environment does not pollute is demanded urgently research and development especially.
Summary of the invention
The present invention is proposed by the problems referred to above, and the present invention provides a kind of magnesium and surface treatment method of Mg alloy, and is applied widely, nonpoisonous and tasteless; Three-waste free discharge does not constitute harm to human body, and environment is not polluted, and technology is simple; Non-scale, do not come off, both attractive in appearance, durable again.
A kind of magnesium of the present invention and surface treatment method of Mg alloy, realize by the following step:
Skimming treatment: carry out wiping with absorbent cotton adhesional wetting solvent orange 2 A, except that after the degreasing, the cotton wiping with cleaning gets final product for 2-4 time again.
Chemical treatment: flood 10min after the degreasing in the solution B under 30-70 ℃, after the washing, in solution B, under 40-55 ℃, flood 5min again, behind distilled water wash, dry below 60 ℃.The solvent orange 2 A parts by weight are: sodium hydroxide 15-25, water glass 10-20, Na
3PO
412H
2O 5-12,
OP-100.b-1.b。
The solution B parts by weight are sodium hydroxide 4-11, chromic oxide 8.5-13.8, calcium sulfate 0.7-1.5, water 60-90.
The solution B parts by weight can also be chromic oxide 10.2-20.5, SODIUMNITRATE 15-20, Glacial acetic acid min. 99.5 90-100, water 95-100.
The solution B parts by weight can also be sodium dichromate 99 6.6-13, sal epsom 3-5, manganous sulfate 5-9, water 65-75.
Advantageous effect of the present invention is that the present invention provides a kind of magnesium and surface treatment method of Mg alloy, and is applied widely, nonpoisonous and tasteless; Three-waste free discharge does not constitute harm to human body, and environment is not polluted, and technology is simple; Non-scale, do not come off, both attractive in appearance, durable again.
