The tubular cathodes made of alloy Ni-Cr-Al-Y for ion-plasma deposition of heat-resistant coatings

           The ELTECHMASH company has mastered the production and started commercial production of tubular cathodes of alloy Ni-Cr-Al-Y for ion-plasma deposition of heat-resistant coatings on MAP-1, MAP-2, MAP-3 units. Exterior view of the cathodes is shown in Fig. 1 (initial state - Fig.1a, after machining - Fig.1b).

      Electron beam melting technology of tubular cathodes allows essentially improve the quality of of the cathodes and eventually the quality of deposition coatings of them, and to refuse their export procurement.
