Description

Chemical nickel bath for iron material

Technical Field

The utility model relates to a chemical nickel bath, in particular to a chemical nickel bath for iron materials.

Background

Electroless plating was designated as electroless plating at the beginning of its appearance, and the most important difference from electrolytic plating is that the deposition process is a chemical redox reaction, not physical deposition. But does not show good industrial applicability in the early stage of occurrence of electroless plating. At the moment, the chemical plating transition liquid has high cost, small adhesive force and easy shedding, and the manufacturing process contains more toxic substances, so the use of the chemical plating transition liquid is greatly limited. But its excellent properties also make it possible to develop rapidly during this period using this method. The reaction mechanism, the catalytic conditions, the reaction conditions and the like are clearly known. The development of this period also makes

The stability of the transition liquid is greatly improved. Subsequently, with the technological progress and the development of industrial technology, the chemical plating technology has been greatly improved. The corrosion resistance of the coating is greatly improved due to the high-phosphorus amorphous chemical coating. The coating layer has an amorphous structure, atoms are disorderly arranged in the coating layer, no crystal boundary exists, and crystal defects such as dislocation do not exist, so that the practical application space of electroless plating is further widened. The stability of the plating solution is improved, and the full-automatic plating is carried out

The technology has been greatly developed, which makes the industrial application of the technology more space-utilizing. With the appearance of low-phosphorus electroless plating with high hardness and high wear resistance, new processes and new technologies are gradually developed, and the electroless plating technology gradually reaches the peak. The chemical nickel plating technology is developed, the performance of the plating layer is stable, the function is varied, and the chemical nickel plating technology can play an increasingly important role in the field of material surface treatment.

The current chemical plating equipment generally hangs a plating piece on a hanging rack and then places the plating piece in an electroplating pool for chemical plating. However, in the case of electroless nickel plating, since the plated article is inflexible, the plated article and the hanger hook are always in a contact state, and the contact portion cannot be plated with a nickel layer. The contact portion may generate black spots, bubbles and peeling.
