The work presents results of diffusion niobizing of titanium Grade 2 by gas-contact method. Microhardness, thickness, chemical composition and microstructure were investigation. Diffusion processes was carried out in a two powder mixture. First consisted of ferro-niobium, kaolin and ammonium chloride, second mixture contained pure niobium instead ferro-niobium. The processes were carried out at 950°C, 1000°C and 1050°C for 2, 4 and 6 hours. Due to the geometric surface structure quality and other properties like thickness or microhardness, the best diffusion layer was obtained using first powder mixture and following parameters: temperature 950°C and time of diffusion equal 2 hours. The diffusion layer established in these conditions, had structure of niobium solution in titanium, and niobium content of about 10%. Its hardness was 550 HV0.05 while thickness was 120 μm.

Comparison of microstructures between LPSed and SSSed SiC ceramics were made. Several kinds of structure defects for LPSed SiC were emphasized to discuss. They related with whole flow path of processing, compositional design of powder mixture, spray granulation of powder mixture, milling, shaping, and sintering control. All could affect the microstructure and mechanical property of resultant ceramics.
