Rhenium diboride
Product Description
Rhenium can improve the creep strength of nickel superalloys, which can be used to make jet engine combustion chambers, turbine blades and exhaust nozzles. Rhenium-nickel alloy is the core material of modern jet engine blades, turbine disks and other important structural parts. The use of rhenium can not only improve the performance of nickel-based superalloys; it can also produce alloys for single crystal blades. The effects of these two aspects can make the turbine (especially the high-pressure turbine) work at a higher temperature.
Rhenium diboride (ReB2) is a boron-containing additive with anti-oxidation, anti-erosion, and thermal strength improvement. It is widely used in nuclear industry, aerospace high-temperature materials, new superconducting materials and other fields.
