Rezumat:

In this second part of researches the compacted composites was presintering at 400 degrees C/30 minutes and sintering at different temperatures between 520 and 620 degrees C/ 1 hour maintaining, both thermal treatment made in protective atmosphere for achieved advanced matrix homogeneity and maximum densification. Sintered samples were investigated by parallel techniques, in terms of density/ porosity, dimensional changes during sintering and mechanical and microstructural point of view. The microstructure of composite has been studied by electron microscopy with electron Electron Probe Micro Analyzer and for identifiy the present phases after presintering sintering treatment was analyzed using X-rays diffraction. The aim of investigations are obtaining the optimal combination of characteristics in concordance with requires of the European market: to obtaining a compacted, wear resistant and non-pollution for the environment material, for automotive destination.
