Research mechanical and corrosion properties composite aluminum alloys Al-TiC
The addition of nano-sized particles of titanium carbide improves the mechanical properties of the alloys without degradation of the starting of the corrosion resistance. The relevance of the study of aluminum alloys and composite application of self-propagating high-temperature synthesis to produce alloys of Al-TiC is shown. Preparation process of the charge and a composite alloy is described. The results of studies of mechanical and corrosion properties of the composite alloys aluminum matrix modified nanoparticles of titanium carbide TiC are provided. Alloys compositions such as: Al - 10 % TiC, AK7 +10% TiC and AK9ch +10% TiC were studied, as well as the starting matrix materials: pure aluminum and AK9ch. The plasticity index wad obtained by calculation. This value showed that the experimental samples are small crystal materials and nanomaterials. It is shown that the addition of nano-sized particles of titanium carbide improves the mechanical properties of the alloys without degradation of the starting of the corrosion resistance.
