A comparative analysis of the efficiency of zirconia ceramics high-energy electron beam sintering by one-step mode and two-step mode sintering was performed for compacts prepared from commercial TZ-3Y-E grade and plasmo-chemical powders. The electron energy was 1.4 MeV. The samples were sintered in the temperature range of 1100–1300°C. The extent of influence of one-step and two-step sintering mode on the characteristics of sintered ceramics depends on the initial powders. Сorrectly chosen the temperature mode of two-step sintering (Ts1=1300°C t = 15 min, Ts2=1200°C t=1 h) leads to an increase of the density and microhardness values of ceramics relatively considered of results at one-step and two-step mode of sintering. |
