Plasma Spray Electrodes

Product Description

Condition : New Brand : Zhuzhou Weilai New Materials Technology Country of Origin : China Product Details:- It is a kind of surface strengthening and surface modification technology, It can make substrate surface coating, and also can be used to prepare sputtering target material. In the process of plasma spraying, A DC arc is generated between the tungsten-containing cathode and anode, and the incoming working gas is heated and ionized into a high temperature plasma to form a plasma flame, The melted spray powder is evenly coated on the surface of the substrate. During this period, the tungsten electrode and nozzle are ablated and worn, resulting in failure. Doped with rare earth elements in tungsten electrode, the electron spillage work can be effectively reduced to ensure good arc initiation performance.The non-destructive bonding between tungsten and copper ensures that the bonding surface is free from defects such as solder metal and pores, and has a bonding strength far greater than that of brazing.The good electrical and thermal conductivity between the two can effectively slow down the ablation of the tungsten electrode and prolong the service life.
