In the surface treatment industry, we often hear relevant technicians mention the three words hydrophilicity, water repellency and hydrophobicity for surfaces. When we mention these terms, we think of "lotus". As we all know, when rain falls on leaves, the water does not disperse, but appears on the surface as water droplets. The main reason for...
Abrasive materials play an indispensable role in the field of surface treatment. In addition to removing the burrs of the workpiece, additives can be added to achieve a polishing effect on the workpiece. Due to the diversity of appearance and different materials of today's workpieces, a variety of shapes and compositions have been extended to meet...
Since today's requirements for metal materials are more comprehensive, if you want to improve the strength and hardness of metal, you need to use "heat treatment" to achieve it.
The electroless nickel process is quite common in Taiwan. It mainly coats raw materials with a nickel layer so that the original workpieces can have high hardness, high wear resistance, and good corrosion resistance. It is suitable for copper, iron, Aluminum, stainless steel, powder metallurgy, zinc alloy and other metal materials. After treatment,...
The same workpiece can present different effects and functions through different processes according to different needs. As shown in the picture above from right to left: aluminum alloy material, anodized treatment (black) and chemical nickel. Next, we will briefly introduce each process to let you understand.
As the name suggests, "roughening" refers to the roughening of a smooth surface through physical or chemical treatment. The most common physical treatment is the use of aluminum oxide emery grit, which is determined by the particle size and size of the emery grit. The pressure of the sandblasting equipment produces surface effects of different...
It is to immerse the workpiece (or parts) in the electroplating solution. After electrolysis, the metal ions (such as nickel, copper or silver, etc.) in the electroplating solution will be coated on the surface of the workpiece; after a period of immersion, the workpiece will The surface layer will be covered with a layer of metal ions from the...
