Q: What are the uses of molybdenum in coating industry?
A: In recent years, the LCD (Liquid Crystal Display), PDP (Plasma Display Device) and other planar display electrodes and wiring materials like molybdenum alloy targets have attracted more and more attention. In TFT-LCD, the gate electrode is a key component, which was mainly used as the gate electrode material with Cr/AL. With the large scale and high precision of flat display, the demand for the specific impedance of the material is higher than that of previous. Besides, the specific impedance and membrane stress of chromium is only one half of molybdenum, and it is harmful to the environment and health due to the production of hexavalent Cr during etching. As a result, more and more companies are switching to Mo/AL as grid electrode materials, so the demand for molybdenum targets is increasing.
Molybdenum targets can be used with other target materials in sputtering or other technological conditions, which are widely used in semiconductor wiring, medical treatment, mechanical processing and solid lubrication.
Another important application of molybdenum in coating industry is spraying. The surface spraying molybdenum on the surface of the piston ring, bearing, extrusion equipment, engine block and turbine components can improve the wear resistance.
