Some customers ask why the pre-treatment step of degreasing should be added before tin plating of cold rolled steel plates? And how to choose the right steel electrolytic degreasing powder?
In the pre-treatment stage of the plating process, conventional pickling processes (hydrochloric acid, etc.) are usually used to remove oxidized layers and rust from the surface of the workpiece. However, this process can lead to hydrogen embrittlement of the plated layer, which significantly affects the mechanical properties and service life of the plated product. Hydrogen embrittlement is a phenomenon in which the ductility and toughness of a material are significantly reduced in the presence of hydrogen, leading to an increase in its brittleness and susceptibility to fracture during use.
In the electroplating process, removing wax is an easily overlooked but important production process. In this article, we will introduce the definition of dewaxing water and the role of Bigely dewaxing water in the electroplating production process.
Electroplated colored zinc passivation process is vital in the corrosion protection of steel and metal products. The passivation process is mainly divided into two types: trivalent chromium passivation and hexavalent chromium passivation, and each of these two technologies has its own advantages and disadvantages. In this article, a detailed comparison of trivalent chromium and hexavalent chromium passivation will be made in terms of the performance of the passivated film layer, the production cost and the environmental protection cost, in order to help plating factories to choose the suitable passivation process.
After we perform palladium activation in the plastic plating process, we also need to perform accelerating. What is the main function of the accelerating? What kind of electroplating accelerator do we need to choose? Let's discuss these two questions in this article.
The advantages of electroless nickel plating lie in its properties such as uniformity of plating, high corrosion resistance, and high hardness. However, in practice, the sudden decrease of plating speed is a common problem that needs to be solved in time. In this paper, we will introduce the electroless nickel plating process, and discuss in detail the possible reasons for the sudden decrease in plating speed and the measures to solve the problem.
