Abstract
The invention discloses a titanic carbide electrolytic stripping solution and the ratio thereof is as follows (content of one liter of solution): 100ml to 150ml of hydrogen peroxide, 10g to 20g of non-hydrochloric soluble chloride, 2g to 5g of soluble substance with acetate, 15g to 20g of hexamethylenetetramine, 50ml to 100ml of hydrochloric acid and water as the balance thereof. When the electrolytic stripping solution is electrified, a small amount of hypochlorite is produced at the anode; the hypochlorite has strong oxidbillity, can break the Ti-C bond, so as to strip; in addition, because of an enough amount of hexamethylenetetramine anode inhibiter, the solution can protect the matrix, meanwhile, the hydrogen peroxide and the soluble substance with acetate assist in the inhibition, hydrochloric acid and the non-hydrochloric soluble chloride provide chloridion, the hydrochloric acid also provides hydrogen ion, so the electrolytic stripping solution can totally strip the titanic carbide cladding layer but not corrode the matrix, and can be widely applied in the stripping of the titanic carbide cladding layer of a Beta-Ti substrate.
Description
Technical field
The present invention relates to the metal material surface process field, particularly a kind of titanium carbide electrolytic stripping solution and complete processing thereof.
Background technology
The β that the balance aspect is good between cold-workability and intensity, the ductility-Ti alloy is in order to strengthen its durable tolerance; Usually on β-Ti base material, plate titanium carbide coating; In the process of plating titanium carbide; Because some accidentalia tends to make the coating that is obtained not meet specification of quality and produce substandard products.When this situation occurring, the coating of substandard product must strip.Present strip method is divided into two kinds usually, and first kind is adopted chemistry to move back, though operation is simple for this method, it adopts alkaline matter as decoating liquid, can have corrosive nature to matrix like this, thereby makes post-treatment operation difficulty; First kind is adopted the alkaline electro unwind, and this method can only be removed most titanium carbide coating, owing to the reason of oxidation makes bottom coating to remove, brings difficulty to post-treatment equally.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention provides a kind of result of use good titanium carbide electrolytic stripping solution.
Another object of the present invention is that a kind of technology of producing above-mentioned electrolytic stripping solution will be provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of titanium carbide electrolytic stripping solution; The proportioning of one liter of solution is: ydrogen peroxide 50: 100～150 milliliters, the soluble chloride of non-hydrochloric acid: 10～20 grams, solubility contain the acetate material: 2～5 grams, hexamethylenetetramine: 15～20 grams, hydrochloric acid: 50～100 milliliters, surplus is a water.
A kind of method of producing above-mentioned titanium carbide electrolytic stripping solution, its step is following:
1): take by weighing various raw materials in proportion;
2): soluble chloride, the solubility with non-hydrochloric acid contains the acetate material earlier, hexamethylenetetramine adds 1/2 water mixing stirring;
3) adding hydrochloric acid in the liquid that: then in step 2) obtains mixes;
4): the last water that in the liquid that step 3) obtains, adds ydrogen peroxide 50 and remainder mixes stirring and gets final product.
The invention has the beneficial effects as follows: during the energising of this electrolytic stripping solution; Anode has micro-hypochlorite to generate; Hypochlorite has strong oxidizing property can interrupt the Ti-C key, thereby reaches the purpose of strip, and owing to contain the hexamethylenetetramine anodic corrosion inhibitor of capacity in this solution; Play the effect of protection matrix; And ydrogen peroxide 50, solubility contain soluble chloride that the acetate material plays effect, hydrochloric acid and the non-hydrochloric acid of auxiliary inhibition and provide cl ions, hydrochloric acid also to play band to provide hydrionic effect, this electrolytic deplating process fluid power to return titanium carbide coating fully and etched the matrix not, thereby be widely used on the titanium carbide coating strip of β-Ti base material.
A kind of titanium carbide electrolytic stripping solution; The proportioning of one liter of solution is: ydrogen peroxide 50: 100～150 milliliters, the soluble chloride of non-hydrochloric acid: 10～20 grams, solubility contain the acetate material: 2～5 grams, hexamethylenetetramine: 15～20 grams, hydrochloric acid: 50～100 milliliters, surplus is a water.
A kind of method of producing above-mentioned titanium carbide electrolytic stripping solution, its step is following:
1): take by weighing various raw materials in proportion;
2): soluble chloride, the solubility with non-hydrochloric acid contains the acetate material earlier, hexamethylenetetramine adds 1/2 water mixing stirring;
3) adding hydrochloric acid in the liquid that: then in step 2) obtains mixes;
4): the last water that in the liquid that step 3) obtains, adds ydrogen peroxide 50 and remainder mixes stirring and gets final product.
For ease of the present invention is further understood, combine specific embodiment to describe the present invention at present.
