Electroless nickel plating technology is famous for its good corrosion resistance, uniform coating thickness and hardness. After the use of electroless nickel plating solution Ni-811, the hardness of the coating can reach 550-650 HK100 after plating. Then, through further heat treatment at 400℃ for one hour, the coating hardness can be further increased to 850-950 HK100. Why is Ni-811 so special? We will examine this problem in the following.
I. Key factors for high hardness
1. Phosphorus content:
The phosphorus content in nickel-phosphorus alloys has a direct effect on the hardness and wear resistance of the plated layer.Ni-811 electroless nickel plating solution enables the plated layer to reach the appropriate hardness after plating and heat treatment by controlling the phosphorus content well.
2. Application of additives:
The additive can affect the microstructure and defect distribution of the coating. Ni-811 contains a variety of additives to make the coating grain fine and uniform, thereby enhancing the hardness and wear resistance of the coating.
3. Heat treatment strengthening effect:
Heat treatment can promote the structural transformation of the coating and enhance its hardness. Heat treatment at 400℃ for one hour after plating helps to form a more complex nickel carbide structure and improve the hardness of the coating.
II. Advantages of Ni-811
1. Durability and uniformity:
The durability and uniformity of the coating are crucial to its application performance. Ni-811 plating solution provides a coating that is not only hard, but also extremely uniform in thickness distribution and can cover complex shapes and deep-hole components with nickel plating.
2. Environmental protection and economy:
Bigely Technology is committed to environmental protection, Ni-811 plating solution is lead-free and cadmium-free, complying with the EU ROSH requirements, and its deposition speed is fast, which helps to reduce the production cost.
Electroless nickel plating solution Ni-811 can not only provide high hardness coating after plating, but also further increase hardness through subsequent heat treatment to meet the high requirements of industrial applications. Combined with its ease of operation and environmental protection characteristics, Ni-811 helps to improve the production efficiency of electroplating plants.
