The result of expansion of protective part on tungsten more than tungsten and less than tungsten needs to be explained. Concept Introduction: There is a need to provide a protective coating on tungsten as at high temperatures, more than 540 0 C , the surface tends to react with the contamination of atmospheric gases. A various number of formidable problems have to be overcome before the full potential of tungsten and tungsten-based alloys reach high temperatures. The other benefits of providing protective cooling are as follows: High bond strength Low porosity, less than 0.5% Low residual stresses High resistance to wear High resistance to corrosion
