About Ternary Complex Process of Tungsten Electrodes

People never stopped research on tungsten electrodes , thoriated tungsten electrodes from the basic to the present cerium tungsten electrode , lanthanum tungsten electrode , and the composite rare earth tungsten electrodes , gradual process and product quality innovation and progress forward . The composite rare earth tungsten electrode is the latest scientific research , our scientists are only carried out vigorously develop . One called ternary complex of tungsten electrode product was born.

Ternary rare earth tungsten electrode is a newly developed green electrode products, with excellent overall welding performance. This is the most promising substitute radioactive contamination of thorium tungsten motors, but because rare earth compound added three constituents , so the production process to bring a new problem , the tungsten electrode swaged and brushed finished products during processing rate decreased significantly. The researchers based swaging process temperature and pass deformation in different designs of the two processes. Plasticity of the electrode integrated use of the various stages of the process of optical metallographic microscopy , scanning electron microscopy and X- ray diffraction analysis and other methods of processing materials were obtained electrode microstructure analysis, we found the two in the formation process fibrous tissue with different characteristics . Good processing performance in which processing technology , fibrotic tissue fibers of uniform width , between the fibers arranged in neat rows . The researchers found that the type of processing parameters of the various stars fibrous tissue , and thus have different yield. Swaging process by adjusting the process parameters to improve the ternary complex of rare earth tungsten electrode production yield.

Ternary complex of rare earth production and application of tungsten electrodes , longevity good economic and social benefits.
