Composite Tungsten Electrode Application-Ⅱ

Composite tungsten electrode is an electrode adding two or more rare earth oxides into tungsten, which are complementary to improve their welding performance. Therefore, they become extraordinary in electrode family. There are different standards for composite tungsten electrode. National standard IS06848 and American standard AWSA5.12 are two of them. The surface condition of composite tungsten electrode is glabrous, clean, no default (fissure, palling), no burrs, and no inner defects on the fracture surface and no oil fouling.

Certainly, composite tungsten electrode has other applications.
Nickel-tungsten- composite tungsten electrode in hydrochloric acid solutions
Composite electroplating is developing rapidly which has been widely used in industries. In view of the squandered metal in composite electrodeposits, for example, the squandered nickel in nickel-tungsten-tungsten carbide composite electrodeposits. Nickel-tungsten-tungsten carbide composite electrode can improve effects of the amount of codeposited tungsten carbide particles, temperature and concentration of hydrochloric acid on the anodic behavior of nickel-tungsten-tungsten carbide composite electrode in hydrochloric acid solutions.
