Description
Technical field
The present invention relates to a kind of mechanical deposit cadmium additives, belong to field of metal surface treatment technology, are used for steel system
The mechanical deposit of part surface cadmium coater, Specifically, it belongs to metal electroplating technical field on steel substrate.
Background technology
Cadmium plating is there are potential environmental pollution, and coating easily occurs that hydrogen embrittlement, cadmium are crisp, but due to its have it is above excellent resistance to
Marine environment performance, so cadmium plating is still the primary protection measure of the spare base steel parts of extra large tooling at present, especially
The surfacecti proteon of fastener, connector applied to ships equipment etc., cadmium plating is still main first choice；Current cadmium plating is basic
Using cadmium plating technique, easily there is hydrogen in the cadmium plating of the high strength steel bolts such as 300M, 30CrMnSiNi2A, A-100 and connector
It is crisp, cadmium is crisp, drastically influence the fatigue life of basis material.
Compared with traditional plating and hot dip, mechanical deposit plating is held after having operation at room temperature, plating without hydrogen embrittlement, thickness of coating
It is easy to control, without cadmium ion diffusion, without temper softening many advantages, such as；Again because mechanical deposit plating process does not have electrolytic effect,
There is no high-temperature metallurgical reaction；So mechanical deposit plating process is not electrolysed liberation of hydrogen, the more not erosion of high-temperature molten metal.Institute
To consider that mechanical deposit method, which prepares cadmium coater, apparent advantage from hydrogen embrittlement and the crisp Producing reason of cadmium.But cadmium metal is different
In metallic zinc, zinc belongs to anode loss protection to steel substrate, and the electrode potential of cadmium is just than iron, therefore cadmium belongs to steel substrate
Cathodic protection coating.Because zinc, cadmium electrode current potential are different, Yi Jixin, cadmium and ferroelectricity electrode potential sorting position difference, cause to pass
The mechanical deposit zinc principle of system and the activator of mechanical deposit zinc can not indiscriminately imitate the mechanical deposition process of cadmium.Experiments have shown that
When using mechanical deposit zinc technology plating cadmium, the deposition velocity of cadmium powder is slow, and coating is thickened less than 10 μm the addition of cadmium powder after ten minutes,
Deposition process is unstable, and the effective rate of utilization of cadmium powder is less than 50%, it is difficult to obtain the coating of expected thickness.Document inspection both domestic and external
Rope shows that the correlative study in relation to the technological process of mechanical deposit cadmium, additive, technological principle etc. is very few.In consideration of it, being directed to
Problems existing for traditional cadmium plating, the Quick mechanical study on deposition for carrying out cadmium coater have important practice significance, this
It is field of metal surface treatment technology scientific workers' urgent problem to be solved.
Invention content
The deficiency that present invention aims to solve the prior art proposes a kind of mechanical deposit cadmium additive, realizes steel
The Quick mechanical of article surface cadmium deposits, and the component and mass percent of the additive are：Butynediols 1% ~ 3%, emulsifier

Change stannous 10 ~ 18%, surplus as water, the sum of mass percent of all components is 100%.
It is technical grade industrial chemicals that the group of mechanical deposit cadmium additive of the present invention, which is grouped as,.
The preparation method of mechanical deposit cadmium additive of the present invention：Water and citric acid are added first into container, so
After butynediols, emulsifier op-10, sodium lignin sulfonate, apple sodium saccharate, cadmium sulfate, stannous chloride, after stirring evenly is added
Obtain additive aqueous solution.
Mechanical deposit cadmium of the present invention with additive using when thickness of coating often thicken 10 μm when activator additive amount Q
For：
Q：Additive amount, units/ml；
S：The surface area of plating piece, unit m2；
40~45：Coefficient is chosen according to the flatness on plating piece surface from 40 to 45.
Processing step when mechanical deposit cadmium of the present invention is used with additive is as follows：
（1）Pretreatment：Using plating, hot-dip, the common degreasing degreasing method of mechanical plating craft for example thermokalite method, supercritical ultrasonics technology,
Oxidizing process etc. removes the grease of workpiece surface, using plating, hot-dip, the common derusting method of mechanical plating craft such as chemical pickling
Method, sandblasting shot-peening etc. remove the rust deposite of workpiece surface, and clean metal surface is exposed on pretreated steel piece surface.
（2）Establish Cd-Sn bases：General mechanical plating equipment is used using similar to mechanical zinc-plating method, by machine
Cadmium powder is added in tool coating apparatus roller and stannous sulfate establishes Cd-Sn bases on steel piece surface.
（3）Cadmium plating：Cadmium powder is added into drum, and additive aqueous solution is then measured and be added according to the surface area of plating piece,
Wait for that roller rotates 3~5 minutes（This process can repeatedly recycle addition cadmium powder, additive aqueous solution according to desired cadmium layer thickness, follow
The time interval of ring charging is 3~5 minutes）.
（4）Post-processing：When reaching desire thickness of coating, discharging, separation, plating piece are dried at a temperature of not higher than 120 DEG C, steel
Article surface can be obtained one layer of bright argenteous cadmium coater.
Beneficial effects of the present invention：
（1）The fast deposition of cadmium powder is realized, coating thickens soon.
When mechanical deposit cadmium of the present invention additive is added in plating cylinder, matrix surface occurs for the component in additive
Effect, it is ensured that cadmium powder particles surface is constantly in clean conditions, while the plating solution environment that additive is added promotes cadmium powder
The current potential on grain surface is negative to be moved, and the absorption deposition of cadmium powder is accelerated, can be in a relatively short period of time（3~5min）Obtain 10 μ m thicks
Coating deposition, be significantly faster than mechanical deposit zinc activator plating cadmium thickens speed（10min coating is thickened less than 10 μm）.
（2）The stably depositing of cadmium powder is realized, coating thickens uniformly.
After plating cylinder is added with additive in the Quick mechanical deposition cadmium of the present invention, additive is dissolved in plating solution, can control cadmium
Powder has suitable agglomerate size, realizes that cadmium powder or cadmium powder ball in matrix surface continuously uniform adsorption, deposition, have reached each
Coating thickens uniformly in a feeding study on period.
