In the hard chrome plating process, the dispersing ability of the plating solution plays a vital role in the quality of the plated layer. Dispersing ability refers to the ability of the metal ions in the plating solution to deposit uniformly on the electrode surface. Improving the dispersing ability of the plating solution results in a more uniform and defect-free coating, which improves the wear and corrosion resistance of the parts. The following are some of the main factors that affect the dispersing ability of hard chrome plating solutions.
In the sulfamate nickel plating process, excessive impurities in the plating solution, especially iron impurities, can seriously affect the quality of the final plated layer. In order to ensure a homogeneous and defect-free plating layer, timely and effective removal of iron impurities is essential. Bigely impurity remover Ni-391 for nickel plating provides a reliable solution to this problem.
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.
