What is involved in brass plating?
Brass plating is the process of storing a thin layer of brass on the surface of the metal object. This process is carried out in a chemical bath that is charged with electricity. The thickness and quality of the brass plating is determined by the length of time in the bath, used chemicals and tank configurations. In this process there is a substrate - a metal object or a surface on which brass plating will be applied - and the brass source is immersed in a chemical bath. Electricity enters the system via brass and goes through the substrate. It bears the particles of brass with a solution towards the substrate. Once these particles have reached the substrate, they settle on the surface and bind to it.
The composition of the chemical bath in which the brass is immersed by brass plating is almost always performed in a solution of cyanide. Although they also take other chemicals that can be used, most companies continue to use cyanide because they react well with brass. The creation of a layer of brass plating on the substrate can take anywhere from a few hours to a few days or weeks. The time that pRoches lasts, depending on the desired thickness of the final product.
The chemical bath temperature also affects the time that takes the growth of brass plating. The optimal temperature range is between 95 and 105 degrees Fahrenheit (35 and 40.5 degrees Celsius.) The plate grown at 75 degrees Fahrenheit (24 degrees Celsius) will take about twice as long as it is grown at the optimum temperature range.
There are different types of containers that can be used for brass plating, the most common is barrels and tanks. Electropping the barrel is useful for small objects that must move freely around. The barrel rotates throughout the process, which creates a uniform brass surface on all sides of the substrate. Electropping the tank is more often used with large metal leaves. At the tank electrical floor, the substrate is lowered into the tank where the plating is evenly mounted on a flat substrate surface.
