FCC/FCC Composite Coating Revolutionizes Aero-Engine Fuel Pump Durability

New Al10Cr28Co28Ni34/Ag composite coating achieves near-zero wear and cavitation erosion resistance in aviation kerosene, promising safer aero-engine fuel pumps.

This breakthrough directly addresses a critical challenge in aerospace engineering: the combined wear and cavitation erosion of fuel pump friction pairs, which can lead to lubrication failure and reduced fuel delivery efficiency. By achieving near-zero wear and long-term cavitation erosion resistance in a single coating, this technology could significantly enhance the reliability and lifespan of aero-engine fuel pumps, thereby improving flight safety and reducing maintenance costs. The innovative use of FCC/FCC structural compatibility opens new avenues for designing advanced protective coatings for extreme environments, with potential applications beyond aviation in marine and industrial machinery where cavitation and wear are prevalent.
