The requirements for electric contact joints between workpieces in the core columns of Kastner furnaces are formulated. The choice of a material - graphite foam - for making electric contact gaskets is justified. Rational form and thickness of electric contact pads have been determined, the glue for their fixation between electrode blanks has been selected. A mold for forming electrocontact pads has been developed and prototypes of pads of different shapes, thickness and density have been made in order to check their suitability for forming Kastner furnace core under industrial conditions.

Showing an increase tribotechnical characteristics of titanium alloys in terms of friction without lubrication, abrasion wear, heat resistance, corrosion resistance the surface after diffusion saturation with nitrogen, carbon, oxygen, chromium, aluminum.

The possibility of intensification of diffusion saturation by introducing into the reaction space activators and activation of surfaces prior Magneto-abrasive treatment that is saturated. This reduces the saturation temperature of titanium and its alloys to 550-900 0C saturation and reduce time to 2-3 hours.
