  • The use of additives in the hard chrome plating process can make a significant difference in the quality and appearance of the plated layer. Hard chrome additives are often used to control the plating rate, adjust the microstructure of the layer, increase the brightness of the layer, reduce stress and improve the overall performance of the layer. However, the use of additives needs to be properly controlled, as inappropriate use or imbalanced ratios can lead to problems such as pitting of the plated layer.

  • Yellowing of zinc-nickel alloy plating in the low current region is usually related to process parameters, bath composition and operating conditions. The following are a few possible causes of yellowing in the low current region:

  • Electroplating hard chrome is a common surface treatment process, which is mainly used to improve the corrosion resistance, hardness, wear resistance and improve the friction characteristics of metal surfaces. This process is used in many fields, such as automotive, machinery manufacturing, mold making and so on. As a commonly used industrial material, carbon steel pipe has good mechanical properties, but it is more general in terms of corrosion resistance and surface hardness, and its performance can be effectively improved by electroplating hard chrome.

  • Tin electroplating usually has good corrosion resistance and can pass a salt spray test for a certain amount of time, which is a common way to evaluate the corrosion resistance of the coating. The salt spray test is to spray a fog containing a certain concentration of salt water into the sample in a specific environment, and then expose the sample for a period of time to observe whether the surface corrosion phenomenon. Salt spray testing can be performed according to different standards, such as ASTM B117, ISO 9227, etc., and the test conditions and duration can vary depending on the application or customer's needs.

  • Wetting agents play an important role in the bright sulfate copper plating process , mainly used to reduce the surface tension, so as to improve the contact between the bath solution and the surface of the object to be plated, to enhance the fluidity of the solution and to prevent the adhesion of air bubbles on the surface of the workpiece. Failure to add a wetting agent to the bright sulfate copper plating bath can lead to a variety of plating failures.

  • The interaction of the different components in the potassium chloride galvanizing system is complex. The fact that the plating is not bright instead of bright after the addition of a potassium chloride galvanizing brightener may be due to a number of factors, and here are some possible explanations:
