Problems solved by technology

In addition, when the mesh belt resistance furnace is used for quenching, the oil and dust on the surface of the workpiece are mixed together and sintered into stubborn solid grease. , It is difficult to completely remove the above dirt during electroplating. Hydrogen bubbles tend to adhere to the dirt and are difficult to discharge, resulting in pinholes and pitting in the coating, and as the bubbles gradually grow, the coating will automatically burst. , produces peeling phenomenon, which leads to the disadvantages of poor heat resistance of the plating solution, serious corrosion and high configuration cost

Abstract

The invention relates to a plating solution, made from, by weight, 1-6 parts of potassium sodium tartrate, 4-11 parts of thiohydantoin, 15-20 parts of sodium octyl sulfate, and 40-50 parts of nickel sulfate solution. The plating solution has stable composition; a plating layer made with the plating solution has good heat resistance, rarely experiences spot corrosion and has long life.

Description

technical field [0001] The invention relates to the field of electroplating, in particular to an electroplating solution. Background technique [0002] During the machining process, thick dirt will form on the surface of parts. If the above dirt is not removed before heat treatment, it will be hard to clean after quenching and sintering into stubborn solid oil and rust, and bubbles will adhere to it during plating to form gas retention pinholes in the coating. The surface of the heat treatment workpiece will inevitably adhere to a layer of oil. When the dust falls on the surface and mixes with the grease, it will be difficult to clean it after a long time, so that the surface of the workpiece will form small oil spots that are not obvious. When air bubbles stay on it, pinholes are formed. In addition, when the mesh belt resistance furnace is used for quenching, the oil stains on the surface of the workpiece are mixed with dust and other impurity particles, and sintered int...
