Electroplating equipment Electroplating technology, also known as electroigneous rock, is the fourth key way to get metal coating on the surface of raw materials. Under the effect of AC electric field, the control circuit is composed of anode and cathode in the electrolyte solution (plating solution), making the metal material in the aqueous solution cation igneous rock to the surface of the cathode plating piece; Current efficiency: the ratio of electricity consumption of igneous rock metal materials to total electricity consumption is called current efficiency of electroplating process.
Decentralized working ability: the dispersing ability of the plating solution refers to the working ability to make igneous rock metal materials spread evenly on the surface of cathode parts under the necessary titanium electrode standard.
Aluminum alloy electroplating process: the whole process of two or about two kinds of positive ions of metal materials on the cathode to produce uniform and fine coatings of igneous rock is called aluminum alloy electroplating process (generally speaking, its minimum multi-component should exceed 1%).
Leveling capability: Leveling capability (i.e. external economic decentralization capability) refers to the capability of the plating solution to make the external economic profile of the coating more linear than the substrate surface when the coating is generated on the stainless steel passivation. It describes the uniformity of the coating spread on the surface of the substrate metal material with relatively small surface roughness, the depth of the wave cavity 1 is less than 0.6 mm, and the distance between the wave crest and the wave trough is not large.
Pinholes or pitting: chlorine gas sticks to the cathode surface in the form of bubbles, preventing the metal material from igneous rock at this position. It only has igneous rock around the bubbles. If chlorine bubbles remain on the cathode surface throughout the entire electroplating process, then the plated coating will have holes or full line through gaps; If chlorine bubbles do not adhere firmly in the whole process of electroplating process, but escape and adhere intermittently, then this position will produce shallow pits or pits, which are generally called pinholes or pockmarks in the industrial production of electroplating process.
Bulging: after the electroplating process, when the temperature of the surrounding medium rises, the absorbed hydrogen accumulated in the base metal material will swell and then the coating will cause small bubbles, which will seriously harm the quality of the coating. This behavior is especially significant in phosphating, cadmium, lead and other metal materials.
Covering working capacity: covering working capacity (or deep plating working capacity) is a key performance parameter of the plating solution, which refers to the working capacity of covering igneous rock metal materials on the surface of cathode parts under the necessary titanium electrode standards, that is, the working capacity of coating igneous rock metal materials in grooves or deep holes under specific conditions, It refers to the level of detail at which the coating is spread over the parts.
Hydrogen embrittlement: After the cathode is restored, some of the hydroxyl ions will produce chlorine gas, and some of them will permeate into the base metal materials (especially in high toughness metal composites) and coatings in the form of molecular hydrogen, which will reduce the ductility of the base metal materials and coatings and make them brittle. This behavior is called "hydrogen embrittlement".
