Electron Beam Melting for tungsten components 181

Tungsten components manufacture use Electron Beam Melting (abbreviation EBM) is an additive manufacturing method. Electrons accelerated under vacuum selectively melt metal powder andproduce a 3D component in an additive way layer by layer. The big advantage of this method consists in the energy source used the electron beam. It is used to pre-heat the metal powder and the carrier plate prior to melting, as a result of which deformation and inherent stress are reduced. It is possible to process materials…

Performance of the Coated Cemented Carbide Tools 1,900

The ratio of coated cemented carbide tools in metal processing industry is increasing steadily. In recent 10 years, its quality and performance have been significantly improved. On the one hand, due to the quality improvement of the coating , it will be better to control porosity and thickness; on the other hand, the metallurgical technology between the coating and the substrate interface has also been improved, therefore can increase the adhesion of the coating and prevent the interfacial reaction that reduces the strength. Increasing cutting speed can significantly…
