The tin plating additives used in the sulfate matte tin plating process have a direct impact on the quality of the plated layer, and the plated layer scratching is often related to the use and regulation of these additives. The type of additives, their concentration and their ratio in the plating solution will affect the final quality of the plated layer.
Austenitic stainless steel, with its excellent corrosion resistance and good plasticity, is widely used in demanding industrial fields, such as chemical, food processing and Marine applications. However, when these materials need to operate in more demanding environments, such as high wear or pressure, additional enhancement of surface hardness and wear resistance is necessary. Electroplating hard chromium is an effective means to improve the surface properties of austenitic stainless steel, not only to improve the hardness, but also to maintain or improve the original corrosion resistance.
In the pyrophosphate copper electroplating process, the control of current density is critical because it directly affects the quality and morphology of the plated layer as well as the deposition rate. Too high or too low a current density can lead to problems with the plated layer, such as roughness, looseness, unevenness, and even defects such as cracks.
In the plating process, the use of acid copper brightener can improve the appearance of the layer brightness, increase the flatness of the copper layer, but when the brightener is used in excess, it will bring a series of problems to the quality of the layer and the plating process. Below we briefly analyze the possible effects of excessive acid copper brightener.
We know that in the copper-nickel-chromium plating process, there are often a variety of failures, in which the poor bonding of the plated layer is a plater often encountered, then, this issue of the article we will discuss the use of alloy chemical degreasing powder, what are the things need to pay attention to, so as to ensure that the bonding of the plated layer is good.
Electroplating is a physico-chemical process that utilizes electrolysis to form a uniform, dense, and well-adhered coating on metals, alloys, or other conductive materials. During the plating process, the cleanliness of the surface of the workpiece is directly related to the quality of the plating. Especially, electroplating degreasing process is one of the key steps to ensure the quality of electroplating.
