Acid bright copper plating process is a special copper plating method characterized by the addition of brightening agents to the plating solution in order to achieve the effect of a bright, smooth copper layer on the metal surface. The main application areas of acid bright copper plating process include the following:
Inadequate bonding of nickel-phosphorus plating can be due to a variety of reasons, and solving this problem requires diagnosing the specific cause and taking appropriate measures. Below are a few common reasons that may lead to insufficient bonding of nickel-phosphorus plating and strategies to resolve them:
Electro-galvanizing is a commonly used anti-corrosion treatment process that protects the substrate from corrosion by depositing a zinc layer uniformly on the metal surface through electrolysis. In order to further improve the corrosion resistance and appearance quality of the galvanized layer, a passivation treatment is usually applied after electro-galvanizing. An important category of passivation is the colorful galvanizing passivate, which provides additional protection to the coating while giving the metal surface a variety of colors that are aesthetically pleasing and practical.
Oil removal is an indispensable step in the plating process and is the key to ensuring good adhesion and surface finish of the electroplating. This article will elaborate on the importance of electroplating oil removal, and introduce the basic concepts of electroplating pretreatment.
Blackening of nickel plated workpieces in air is not usually a normal phenomenon, and may be caused by oxidation or sulfidation of the nickel plated surface. Nickel plating usually has good corrosion and oxidation resistance, but under certain circumstances, such as insufficient quality of plating, presence of contaminants in the environment, high humidity, or poor storage conditions, the surface of nickel plated parts may become discolored or blackened.
