Glaring refers to the flatness and smoothness of the coating surface that is quickly formed after the plating solution is sprayed onto the metal surface during the electroplating process. The quality of glossing has become one of the important indicators for measuring the quality of the coating.

I. Definition and importance of glaring
Electrogalvanizing is a surface treatment method widely used in the field of corrosion resistance. Its basic principle is to form a protective film by coating a layer of zinc on the metal surface to prevent the metal surface from being oxidized or corroded. In the process of electrogalvanizing, heating is a common method to improve the shinning effect.
Glaring refers to the flatness and smoothness of the coating surface formed quickly after the plating solution is sprayed onto the metal surface during the electroplating process. The quality of glaring has become one of the important indicators for measuring the quality of the coating. A coating with good glossing effect can improve its anti-corrosion performance, wear resistance and appearance quality.
II. The effect of heating on the light-emitting effect
During the electrogalvanizing process, heating has different effects on the light-emitting effect. Moderate heating can improve the light-emitting effect. The main reasons are as follows:
1. Heating can improve the fluidity of the plating solution, so that the sprayed liquid is more evenly distributed on the metal surface, forming a smoother surface.
2. Heating can promote the cohesion of the coating surface, help to form a smooth surface, and reduce the uneven surface accumulation, elongation and crystallization.
3. Heating can improve the uniform distribution of impurities in the plating solution, help prevent impurities from adhering to the coating surface and affecting the finish of the coating.
However, too high heating temperature can also have a negative impact on the light-emitting effect, for example:
1. Too high temperature may cause evaporation and precipitation of the plating solution, affect the concentration of the plating solution, and reduce the light-emitting effect.
2. Too high temperature will cause oxidation on the metal surface, resulting in an oxide layer on the coating surface, affecting the light-emitting effect.
3. Too high temperature will accelerate the decomposition of the plating solution and the electrode reaction rate, resulting in impurities and bubbles on the coating surface.
In summary, moderate heating can improve the light-emitting effect during the electrogalvanizing process, but the heating temperature and time need to be judged and controlled according to the actual situation to avoid the negative effects of excessively high temperatures.
