What is electro-nickel plating?
Electroplating and electroplating are distinguished by the precipitation of electrons by energy or the precipitation of chemical action by reducing agents, and there are differences in processing time, price, uniformity, etc.
Electrolytic nickel plating is classified into the second type, electrolytic nickel plating, and is also known as Kanigen plating, a surface treatment that dissolves a reducing agent and deposits nickel on the surface of the material.
Suitable material for electrolytic nickel plating
While the above-mentioned electrolytic plating can only be applied to conductive objects, electrolytic nickel plating uses only chemical action to settle nickel on the surface of the material without the use of electrons. Surface treatment can be applied not only to aluminum, etc. but also to plastic, etc. non-conductive.
This plating is widely used in industry because it is not affected by the properties of the material.
Electrolytic nickel plating accuracy
One of the disadvantages of electroplating is that it is difficult to maintain accuracy after surface treatment because the thickness of the plating layer is uneven.
In electroplating, the plating does not enter a hidden position from the electrode plate, or the plating is thickened at the edge.
Electrolytic nickel plating is done without using electrode plates, so there is no concern that it does not precipitate due to positional relationships, and has no influence from the present, so even if it is a complex shape, the entire plating thickness is processed uniformly. You can do it.
In addition, because the thickness of the plating layer can be controlled in units of m, it is easy to control the dimensional accuracy requirements after finishing by adjusting before plating.
Characteristics of electrolytic nickel plating
Electrolytic nickel plating is classified into high, medium and low phosphorus grades according to phosphorus content, but the properties obtained vary depending on the phosphorus content.
If the phosphorus content is high, it becomes amorphous and the number of pinholes decreases, so that corrosion resistance is improved, and properties such as acid resistance and non-magnetic impact due to temperature are less likely to be obtained.
When the content is low, properties such as improved adhesion to special materials and improved alkali resistance can be obtained.
Medium phosphorus is the most commonly used type because it is flexible and versatile because of the balance of different physical properties.
In addition, the heat treatment after the surface treatment can increase the hardness from about 500 HV to about 1000 HV, so that it can also improve the wear resistance.
Applications of electrolytic nickel plating
Electroless nickel plating is a synthetic plating with added fluororesin, ceramic particles, boron nitride, etc. It is widely used for hard disks, resistors, electronic components, valves, etc., including industrial products, because it is not affected by the high properties and precision that can be maintained.
