Improved of the nanolaminate-ceramic by the additional of aluminium to used in higher resistance hydraulic structures

الملخص EN

It has been tried in this research to introduce this type of new structural materials as reproducible industrial materials and overtake some production obstacles by exploring the direction of chemistry structure relation.

The compacted samples have been prepared from elemental powders (Titanium, Aluminum and Black Carbon) using the powder technology techniques.

They have been dispersed in different concentrations (Ti-Al-C) and different molar ratios due to the change in the Ti to Al concentrations.

Thus the effect of Al concentration on MAX phase evolution in the Ti-Al-C system has been investigated and discussed.

Therefore, the concentration of Al has improved the applications of water resource structures, and that alloy, especially in corrosion resistance and under water, has proved structures as well as pipes because the Al has created the layer that protects this ceramic from hard and nature conditions , So the Al metal lead to use this ceramic in loading bearing structures such as bridges and high impact resistance such as Dams.

The effects of cold and hot pressing as well as sintering in different temperatures are investigated.

Phase evolution is discovered by X-ray diffraction (XRD), and SEM.

Micro hardness test and Archimedes method is used to measure the density and porosity percentage.

No evidence for the direct formation of MAX phases from elemental powders is foud which may explain the need of high temperatures to produce such phases since the breaking of bonds is required for the intermediate phase.
