Hydrogen embrittlement is more common in the electroplating process of steel parts. This is mainly due to the generation of reduced hydrogen atoms in the processes of pickling, cathode degreasing, and electroplating. Sin...
Greases are divided into two categories according to their composition and performance, namely mineral oils and animal and vegetable oils. These two types of oils are called saponified oils (animal and vegetable oils) an...
Various metal products are often contaminated with oil during processing, such as lubricating oil, marking paint, etc., as well as corrosion and oxide scale generated during storage, oxide film or burrs during processing...
For rack-plated products, quality problems in electroplating often occur due to improper suspension. Therefore, the following points should be paid attention to when mounting:(1) The main working surface or decorative su...
The third generation semiconductor mainly refers to the wide bandgap semiconductor materials represented by silicon carbide and gallium chloride, which has unique properties and advantages such as wide bandgap, high volt...
As early as when the National "Twelfth Five-Year Plan" was proposed, we should insist on taking the construction of a resource-saving and environment-friendly society as an important focus point for acceleratin...
Recently, Dr. Kyung-tae Kim's research team at the Powder/Ceramic Research Headquarters of the Korea Materials Research Institute has successfully developed a surface treatment technology for extremely fine aluminum...
Surface treatment of plastic products mainly includes coating coating treatment and plating coating treatment. Generally, the crystallinity of plastic is large, the polarity is small or no polarity, and the surface energ...
Metal materials are increasingly used in various products, because metal materials can better reflect the quality of products and highlight the brand value, and among many metal materials, aluminum is the first to be ado...
