... spraying is currently utilized for the fabrication of axisymmetric thin-wall parts. Tungsten provides the materials designer with the highest density of any nonradioactive, nonprecious metal. The extremely high melting point of tungsten also makes it the material of choice for incandescent lamp...

... Current pattern for periodic-reverse pulse plating in which pulse frequencies have been superimposed on the forward and reverse envelopes On some models, forward and reverse amplitude can be controlled individually ( Fig. 7 ). This permits, for example, a higher current density in the reverse...

... no currents flowing. Figure 10 shows how the eddy current varies as a function of depth below the surface. The depth at which the density of the eddy current is reduced to a level about 37% of the density at the surface is defined as the standard depth of penetration. This depth depends on the...
