With the development of modern industry, aluminum and its alloys are more and more widely used in aviation, automotive, electronics and other industries. However, due to the chemical characteristics of the oxide film and high activity on the surface of aluminum, the electroless nickel plating process commonly used in the industry faces the problem of poor plating bonding when treating aluminum. In order to solve this problem, Bigely Technology has developed an environmentally friendly zinc sinking water BC-22, which effectively improves the bonding strength of the electroless nickel plating layer on aluminum.
Electrolytic degreasing is a crucial step in the electroplating process, aiming at removing the oil on the surface of the workpiece and ensuring the uniform adhesion of the subsequent plating layer. However, alloy workpieces always have problems such as discoloration and corrosion after degreasing, which causes problems for many plating engineers. To address this situation, this paper analyzes this phenomenon and provides effective solutions.
After zinc-nickel alloy plating, colored passivation is often intended to improve corrosion resistance and add aesthetic appeal. However, poor results when performing salt spray testing can stem from several key factors:
Plastic plating is a method of imparting a metallic appearance and performance to a plastic substrate by depositing a metallic coating on it. Roughening is a key step in the plastic plating process and is critical to the quality of the final coating. However, inadequate roughening can cause a number of problems that affect the performance and appearance of the final product. In this article, we explore the effects of insufficient roughening.
The electroless nickel plating process is favored by industry for its ability to uniformly plate nickel on the surface of a workpiece without the need for an applied current. However, electroless nickel plating layers are often deficient in corrosion resistance due to their relatively high porosity, especially in salt spray tests, which limits their application in some harsh environments. In order to improve the corrosion resistance and extend the service life of electroless nickel plating layers, platers often use nickel-plated aqueous sealers for post-treatment.
Some customer inquired that how many hours of neutral salt spray test can the passivated workpiece reach during the production process using electroplated colored zinc passivator.
