what are the new developments and new researches in the construction materials of turbine stator blades ?
What do you think about TiB2-based ultrahigh temperature ceramics? If you list the needed properties, it can help us to select the best material or design a novel composite.

thank you dear Dr. Mehdi Shahedi Asl
TiB2-based ceramics are resistant to corrosion but i have no idea about their rate of fatigue failures ;
so we need materials with this specifications:
1.resistant to fatigue failures
2.high اhot corrosion resistant
3.light and recyclable
specially number 1 & 2 are very important
TiB2-based ceramics are resistant to corrosion and you have to apply the shack effect on these ceramics.
- The advantages of the new turbines do not require large areas, do not cause noise, and practically do not have rotary parts such as turbines with fans, which reduces the cost of maintenance by up to 80% of conventional turbines known for the size of blades and fans, and reduces the proportion of manufacturing costs of approximately 40-50 %.
– مزايا التوربينات الجديدة لا تحتاج إلى مساحات واسعة ، لا تسبب ضجيج، وعمليا ليس فيها أجزاء دوارة كالتوربينات ذات المراوح مما يخفض تكاليف الصيانة بنسبة تصل إلى 80 % عن التوربينات الاعتيادية والمعروفة بضخامة ريشها ومراوحها ، كما يخفض من نسبة تكاليف تصنيعها تقريبا من 40 – 50 % .
Hi
Ultra-high temperature ceramics such as TiB2, ZrB2 and HfB2 are resistant to corrosion and show more uniform temperature distribution and following that less thermal stress. Also they can withstand the applied compressive stresses and do not fail.
