            Póngase en contacto con tungsteno/punto

            A tungsten contact disc is treated by burnishing, so as to smooth and compact the contact surface and remove the surface-crazed metals and oxides, while simultaneously filling the surface pores with a contaminant such as iron. The contaminants present in the pores are subsequently removed by immersing the contact disc in a dissolving agent, and the remaining natural oxides of the tungsten are removed from the walls of the pores by cathodic reduction, to create large pore sites, which are free of oxides and contaminants.
