Problems solved by technology

For example, the working temperature is high (generally 85-95 ℃), the plating solution evaporates quickly, more energy needs to be provided, the energy consumption is large, the investment in equipment is increased, and the plating process is difficult to control; the operation at high temperature will cause damage to some materials. The deformation and modification of the substrate lead to low brightness and poor leveling of the coating, which is not suitable for decoration or chemical plating on plastics.

Abstract

The invention relates to material surface chemical plating, and concretely relates to a solution for realizing the rapid plating of Ni-Co-P on the surface of a low carbon steel substrate under medium-low temperature conditions, and a method thereof. The solution and the method have the advantages of helpfulness for the energy consumption reduction, apparatus investment reduction, plating solution evaporation amount reduction, easy maintenance, less energy consumption, environmental pollution reduction, labor environment condition improvement and operator safety protection; and the obtained plated layer has an improved heat stability, and the hardness of the plated layer is close to that of a high-temperature chemically-plated Ni-P layer.

Description

technical field [0001] The invention relates to chemical plating on the surface of materials, in particular to a solution and a method for quickly plating Ni-Co-P on the surface of a low-carbon steel base material under medium and low temperature conditions. Background technique [0002] The performance of the multi-element alloy coating is better than that of a single nickel-phosphorus coating. Since cobalt has the same self-catalysis properties as nickel, cobalt ions can be introduced on the basis of Ni-P alloy to form a Ni-Co-P ternary alloy coating. Compared with Ni-P coating, Ni-Co-P alloy coating can refine the crystallization and increase the anisotropy of magnetic particles, and is mainly used in various magnetic recording systems. With the high functionalization of computers and electronic communication equipment, the miniaturization, high performance and high frequency of magnetic devices are required, so the requirements for the characteristics of the magnetic mat...
