The aluminum alloy parts must be dipped in the transition metal layer

Such as leaching zinc, tin, nickel metal, to get good coating binding force, now mostly used in mass production with heavy zinc for, with two heavy zinc dominant processes, this because they are usually in zinc, zinc layer of coarse porous, binding force is not good, in order to further improve the adhesion strength of the substrate and the coating, often the Baptist zinc again, so get the zinc layer is smooth, dense. Heavy zinc generally accounted for by the market, since the match each half, since the match on the basis of traditional zinc acid complex salt, then add iron, nickel, copper with organic complexing agent, namely sink into quaternary alloy liquid zinc, since the use of cost is low, the maintenance and management of heavy liquid zinc need to pay attention to the following:

(1) the heavy zinc liquid temperature: heavy zinc had better maintain between 15 ~ 25 ℃, due to the high zinc and other metal replacement too fast, get grey black loose, rough, even spongy layer displacement, the zinc replacement layer binding force is very poor. And at low temperature, heavy zinc liquid mild reaction, such as zinc alloy precipitation quantity is little, zinc alloy, such as replacement layer uniform density, corrosion resistance and the adhesion strength of the substrate greatly improved, so a lot of manufacturer is always complaining about the summer always foam aluminum, aluminium alloy electroplating, actually summer refrigerating machine is indispensable equipment.

(2) zinc time: zinc time and heavy liquid zinc is inversely proportional to the temperature, the concentration (especially the concentration of metal ions), sink in zinc liquid temperature of 15 ~ 25 ℃, the concentration of 20 when the baume degree, heavy zinc time 1 min or so for the first time, a second 30 s, too long will become rough porous and reduced density, uniformity, affect the subsequent working procedure.

(3) strict control of the concentration of Zn, especially the synthesis ratio of alkali and zinc, the optimal ratio of N aO H and Zn is (10 ~ 12) : 1. When the ratio of alkali to zinc is too high, the zinc alloy is crystallized in detail, but the deposition rate is slow on the aluminum alloy surface, the dissolution rate of the aluminum surface is accelerated, and the electroplating is easy to produce the hemp. When N aO H for zinc ratio is too low, the heavy liquid zinc immersion in 3 ~ 5 s, will replace film of zinc alloy, the inversion layer of coarse porous, density difference, electroplating midway will find blister, generally small electroplating factory heavy liquid zinc is commercially available, there is no analysis conditions, concentration determination wave beauty meter alone, according to my experience, below 15 baume degree, can appear some foaming phenomenon, higher than 25 baume degree, should reduce heavy zinc time, of course, should consider the aging condition of heavy liquid zinc, for example, will be dissolved in liquid zinc, aluminum in the sink with the increase of the amount of dissolved aluminum solution baume degree rise, so will produce the error, if out of the small amounts, should be timely replacement part old fluid, a new liquid supplements.
