Description
Technical field
The present invention relates to a kind ofly to be applied to electroplate/Simple electroplating/electro-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 occur between metal and its residing surrounding medium, causes the rotten of metal and degenerates, and is called metallic corrosion.The metallic corrosion problem spreads all over each department of national economy and national defense construction, and annual have a large amount of hardwares and equipment to scrap because of corrosion.It is reported, at present China approximately has 30% iron and steel to scrap because of corrosion every year, wherein approximately 10% because of becoming iron rust, thoroughly scraps, and nearly 1,000 ten thousand tons of the therefore annual and steel that lose 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, such as 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 (mean value) loss.Therefore, metallic corrosion arouses great concern.Research shows, electrochemical passivation or modification are carried out in metallic surface, and in covering, metal or the various protective layers such as nonmetal, separate protected metal and corrosive medium, is the effective ways that prevent metallic corrosion.This process will realize through plating/electrodeposition process usually.The great advantage of this technology 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 by generating protective layer directly blocking-up corrosion physically, can also construct in metallic surface with the contact angle of water and reduce contact area with environment greater than 150 °, roll angle less than the super hydrophobic surface of 10 °, and then reduce erosion levels.
Another important application of plating/galvanic deposit is to carry out decorative electroplating.Decorative electroplating is the electro-plating method of giving aesthetic appearance, and for example plastic electroplating, imitation gold plating,, because their costs are low, have again good landscaping effect, has been penetrated at present the industries such as ornameutal handiwork, five metals production and automobile making.Along with improving constantly of people's living standard, also more and more higher to the requirement of ornament, decorative electroplating has wide practical use.
Existing small-sized electroplating/electro-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 large volume, apparatus structure is complicated, not easy to operate, electrode is fixing insecure, polishing, calcination, cleaning difficulty, electrode area is wayward, and what relate in a lot of processes is all two electrode systems, and the dynamic corresponding relation that this is unfavorable for accurately studying between the electrical signal such as electric current, voltage in plating/electrodeposition process and coating physical features very much, also be unfavorable for meticulous production.
