In order to celebrate the 50th anniversary of the establishment of diplomatic relations between China and Tanzania, the “ Stars Crossing Oceans - China-Africa Maritime Silk Road History and Culture Exhibition†organized by the China Cultural and Cultural Exchange Center was opened on the 15th at the National Museum of Dar es Salaam in Tanzania. This exhibition aims to show the ancient Chinese nautical technology and the spirit of people exploring the unknown world through the historical and cultural theme of the Maritime Silk Road. By reviewing the history of friendly exchanges between China and Africa for centuries, we promoted the Chinese people’s view of advocating peace and the openness of the Chinese civilization. Chrome Plating Production Line
Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.
Chrome plating refers to the act of plating chromium as a plating layer on other metals. Chrome Plating Production Line,Chrome Plating Line,Chrome Electroplating Line,Hard Chrome Plating Line Wuxi Xingyi Intelligent Environment Protection Equipment Co.,Ltd. , https://www.wxxingyi.com
Chromium is a kind of silver-white metal with a bluish tint. Metal chromium is easily passivated in the air, and a very thin passivation film is formed on the surface, thus showing the properties of precious metals.
The chromium-plated layer has a very high hardness, and its hardness can vary within a wide range of 400-1200HV according to the composition of the plating solution and process conditions. The chromium-plated layer has good heat resistance. When heated below 500℃, there is no obvious change in gloss and hardness. The temperature above 500℃ starts to oxidize and discolor, and the hardness starts to decrease when the temperature exceeds 700℃. The friction coefficient of the chrome layer is small, especially the dry friction coefficient, which is the lowest among all metals. Therefore, the chrome-plated layer has good wear resistance.
