Water droplet erosion (WDE) protection of Ti6Al4V turbofan blades is of paramount importance to the aviation industry. A novel CrAlYN/CrN nanoscale multilayer coating deposited by the HIPIMS technique was evaluated as a potential candidate for this a

Rain erosion of turbofan blades creates problems in the aeronautics community, since the changes of profiles on leading edges affect aerodynamic performance that subsequently leads to significant efficiency drop for the aircraft engine. Water-hammer

The radius of typical water droplet, which an aeroengine encounters in-service, and the radius of curvature of a typical fan blade leading-edge are approximately the same; this is unlike previously investigated contexts, where the typical droplet rad

In the aviation industry, water droplet erosion (WDE) takes place when an aircraft takes off on as wet runway or flies through rain or clouds. The leading edge of turbofan blades suffers from high-speed (300–400 m/s) impingements of water droplets,

WC-Co coatings have been used as wear resistant coatings in aero engines for decades, and research is still ongoing to further improve the performance of these coatings through compositional modifications to reduce wear. The coatings are used for unl

High velocity oxy-fuel (HVOF) thermal spray process has shown obvious advantages over other surface hardening techniques when depositing WC-based layers, such as the laser cladding, electrodeposition and chemical/physical vapour deposition (CVD/PVD)

The surface roughening of fan blade leading-edges on large civil aeroengines, due to Water Droplet Erosion (WDE), can lead to a decrease in engine performance and increase the risk of flutter. To model the impingement of a high-speed water droplet on
