Abstract
The invention discloses a composition solution for electric nickel-plating on the surface of a magnesium alloy. The composition solution comprises a zinc immersion liquid, an electric zinc plating liquid and a nickel-electroplating liquid. By adjusting the components of the zinc immersion liquid, the zinc electroplating liquid and the nickel electroplating liquid, a plating process is environmental friendly and safe, and a prepared plated layer is high in corrosion resistance, attractive in appearance and high in binding force with a substrate.
Description
Technical field
The present invention relates to electroplating technology field, relate in particular to a kind of electroplating nickel on surface of magnesium alloy combination solution.
Background technology
Magnesium alloy, as a kind of lightweight engineered structured material, has high specific strength, high specific stiffness and superior damping performance, and field has a wide range of applications in fields such as traffic, communication, Aeronautics and Astronautics.But magnesium alloy chemical activity is high, and electropotential is low, surface film oxide is loose, causes barrier propterty low, has restricted the application and development of magnesium alloy.Cause thus the concern of people to magnesium alloy part surface corrosion and protection, carry out a large amount of research at aspects such as Mg alloy surface anodic oxidation, chemical conversion film, organic coating, coating surfaces, particularly adopt that method for electroplating nickel is low as a kind of cost, technique is simple, the surface coating technique of easy handling, has become the important research direction of people to magnesium alloy surface protective.
At present, the electro-plating method of magnesium alloy could start to electroplate other metal after being mainly zinc-plated, pre-copper facing in advance, and most of for electroplating containing cyanogen.For example, what generally adopt both at home and abroad now is the standard method of the plated metal Ni of U.S. ASTM recommendation, is the zinc plating method of soaking of Dow company exploitation, and its pre-treatment has adopted soaks zinc and cyanide copper plating technique.But, this complex technical process, repeatability is poor, uses prussiate, and plating solution is poisonous, contaminate environment, the bright property of coating and the stability of plating solution also need further improvement.
In order to overcome the shortcoming of complex process, software engineering researchers invent has gone out direct electroless nickel method, as adopted chromic anhydride to carry out etch to magnesium alloy in JP2003073843, after fluorochemical activation, carry out chemical nickel plating, with ammoniacal liquor regulate chemical nickel-plating liquid make it be weakly alkaline, once obtained bonding force good, the chemical Ni-plating layer that solidity to corrosion is high, the high employing in patent CN1699634A magnesium alloy plating method of Li De goes wadding → electrochemical deoiling → bright dipping → neutralization → activation → pre-zincincation to obtain reasonable pre-zinc coating, and pre-galvanizing flux is without cyanogen, nontoxic, harmless, the people such as Yang Noboru are in patent CN1737205A, by Direct Electroplating aluminium after dense hydrofluoric acid used for magnesium alloy (11%) pickling, obtain reasonable aluminium coat, Chinese patent CN1641075A is to magnesium, the surface of magnesium alloy or activating treatment process and plated surface method were done detailed description, although these techniques have all departed from prussiate plating, but the mostly improvement of the technique based on to DOW for the treatment of process before electroplating.
Summary of the invention
The object of the invention is to propose a kind of electroplating nickel on surface of magnesium alloy combination solution, and by the adjustment of soaking zinc, electro-galvanizing plating solution and electronickelling bath composition, do not adopt poisonous, pollute high component, make plating technic Environmental Safety, and the corrosion-resistant height of coating of preparation, appearance looks elegant, matrix and binding force of cladding material are high.
