Abstract
The invention discloses a processing method for the anodic oxidation of a zirconium surface. The method comprises: pickling the surface of a zirconium surface needing anodic oxidation; forming a layer of oxide film on the zirconium surface by anodic oxidation; and washing the formed oxide film-coated zirconium surface. In the processing method, the layer of oxide film is formed on the surface of the zirconium surface, so that the anti-corrosion performance of the zirconium material is improved effectively and the service life of the equipment is prolonged. The method is applicable to zirconium material surfaces needing improvement on anti-corrosion performance.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to the anodised treatment process in a kind of zirconium surface.
Background technology
At present, the corrosion resistance of zirconia material mainly is thickness and the compactness that relies on oxide film, in special medium, for example at H
2SO
4In, being subjected to the influence of high temperature and concentration, the anti-corrosion rate of zirconium significantly reduces.How to improve the solidity to corrosion of zirconium, guarantee that simultaneously the densification of oxide film and corrosion resistant (wear-resisting and solidity to corrosion) become the main difficult technical in the use of zirconium material.
Under certain erosion rate, rely on to increase material thickness and prolong equipment duration of service, so, the Financial cost of equipment is significantly increased, and more thorny is, in the weld seam junction of equipment, realize that the whole uniform thickened difficulty of weld seam is very big, and the weld seam junction corrosion resistant thin spot of equipment exactly, the fillet weld that especially loose lining structure seals, it is big and very unreliable to realize that weld seam integral body thickens difficulty.In the case, press for the corrosion resistance nature that a kind of method can satisfy the zirconium material in the situation that does not increase the zirconium layer thickness.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, provides a kind of zirconia material surface that makes that anodic oxidation takes place, and generates the treatment process of layer oxide film on the zirconium surface.The present invention handles the corrosion resistance that oxide film that the zirconium surface obtains can effectively improve zirconia material, the life-span of improving equipment.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the anodised treatment process in a kind of zirconium surface is characterized in that this method may further comprise the steps:
(1) adopt acid solution to need the position of anodic oxidation treatment to carry out pickling to the zirconium material, till no dirt continued dissolving, water rinsed out remaining acid solution then; Described acid solution is made by following raw materials by weight percent: nitric acid 30%, and hydrofluoric acid 3%, surplus is a water;
(2) the zirconium material after pickling in the step (1) is carried out anodic oxidation treatment, forming thickness until zirconium material surface is the mazarine oxide film of 0.05 μ m～0.06 μ m; The medium of described anodic oxidation treatment is a neutral aqueous solution, and the voltage of anodic oxidation treatment is 25V～40V;
(3) surface of the zirconium material after anodic oxidation treatment water in the step (2) is cleaned to remove residual acid pickling.
The system of pickling is described in the above-mentioned steps (1): the intact back of pickling for the first time water rinses out remaining acid solution, carries out the pickling second time again, till no dirt continues dissolving.
