The article deals with research findings aimed to solve a pressing scientific issue of increasing an operational life of metal-ceramic alloys in extreme run-time environment. This is carried out by means of extension methods of surface processing based on a strategy of additional structural layers on a surface resulted by the influence of low-energy high-current electron beams with sub milliseconds longitude in the environment of inerting and reactive gases. Obtained results reveal some aspects of metal-ceramic alloy’s boundary layer formation at macro and micro layers when they undergo electron beam exposure in different plasma-supporting environment. Experiments have shown that it is possible to change the reactions of interphase interaction of metal-ceramic alloys components when gases with different ionizing energy are used as a plasma-supporting environment in identical exposure modes. This predetermine possibility to create an operated multilevel structures in upper layers of a solid alloy as a result of processing by low-energy high-current electron beams.
