Description

Simple and easy plating/electric deposition device
Technical field
The present invention relates to a kind ofly to be applied to electroplate/the simple and easy plating/electric deposition device of electrodeposition, belong to electrochemical field.
Background technology
These electrochemical techniques of plating/galvanic deposit are widely used in all trades and professions of modern society.Its important application is exactly the metal corrosion protection.Along with the quickening of process of industrialization, metallic substance is used on a large scale, and chemistry, electrochemistry or physical action take place between metal and its residing surrounding medium, causes going bad and degenerating of metal, is called metallic corrosion.The metallic corrosion problem spreads all over each department of national economy and national defense construction, and annual all have a large amount of hardwares and equipment to scrap because of corrosion.It is reported that at present China has 30% iron and steel to scrap because of corrosion every year approximately, wherein about 10% thoroughly scraps because of becoming iron rust, and nearly 1,000 ten thousand tons of the steel of therefore annual and loss are equivalent to the output of Baosteel whole year.Except the Direct Loss that corrosion causes, the indirect loss that metallic corrosion causes is often even more serious, for example polluted product, collapse, life and property loss not count enable especially that blast etc. causes.According to foreign statistic, the year loss of metallic corrosion is considerably beyond the summation of floods, fire, disaster caused by a windstorm and earthquake (MV) loss.Therefore, metallic corrosion has caused people's very big concern.Research shows, to carrying out electrochemical passivation or modify in the metallic surface, metal or various resists such as nonmetal protect quilt metal and corrosive medium to separate coverings in, are the effective ways that prevent metallic corrosion.This process will be passed through plating/electrodeposition process usually and realized.This technological great advantage is that reaction process is controlled, coating even and adhere firmly, and the alloy layer that obtains has corrosion stability, magnetic, the weldability of good physical properties, excellence and can heat-treat.It is not only through generating resist from directly blocking-up corrosion physically, can also construct in the metallic surface with the contact angle of water to reduce the contact area with environment less than 10 ° super hydrophobic surface greater than 150 °, roll angle, and then the reduction erosion levels.
Another important application of plating/galvanic deposit is to carry out decorative electroplating.Decorative electroplating is an electro-plating method of giving aesthetic appearance, and for example plastic electroplating, imitation gold plating because their costs are low, have the good effect of beautifying again, has been penetrated into industries such as artwork making, five metals production and automobile making at present.Improving constantly of Along with people's standard of living, also increasingly high to the requirement of ornamental, decorative electroplating has wide practical use.
Existing small-sized plating/electric deposition device great majority are based on cell design and form, and it has a lot of shortcomings.It not only needs the reaction soln of big volume; Apparatus structure is complicated, not easy to operate, and electrode is fixing insecure, polishing, calcination, cleaning difficulty; Electrode area is wayward; And what relate in a lot of processes all is two electrode systems, and the dynamic corresponding relation that this is unfavorable for accurately studying between electrical signal such as electric current, voltage in the plating/electrodeposition process and the coating physical features also is unfavorable for meticulous production very much.
Summary of the invention
To the existing problem of present plating/electric deposition device, the present invention provides a kind of stable and effective simple and easy plating/electric deposition device.This device is a kind ofly to design based on electrochemical principle; Fixedly plate electrode such as platinized platinum, steel plate is respectively as working electrode and supporting electrode; Constitute a kind of compact construction of three-electrode system, respond well device with reference electrode again, can be applicable to electroplate, material surface processing technology and relevant theoretical investigation such as galvanic deposit.
