▎ 摘　　要

NOVELTY - The structure has a multi-scale micro-structure provided with a micro-convex structure and a micro-concave structure. An inner portion of a turbine blade is provided with a cooling channel. A spoiler rib is arranged in the cooling channel according to preset distance and preset angle. A surface of the cooling channel and the spoiler rib are provided with the multi-scale micro-structure. The multi-scale micro-structure is provided with nickel crystal particles and graphene-shaped redox graphene. USE - Blade for use in a turbine (claimed) with a cooling structure of an aircraft engine. ADVANTAGE - The turbulent flow rib has function of cooling and strengthening heat transfer. The electric brush is plated with a layer of the multi-scale micro-structure on the base of the turbulent flow rib, which can increase specific surface area of convection heat exchange, improves disturbance of cooling fluid on a wall surface and heat conductivity coefficient of fluid heat-conducting equivalent, so as to obviously provide heat exchange effect. The structure has obvious effect on cooling strengthening heat transfer in a high temperature nickel base alloy turbine blade of an aircraft engine, and has wide application prospect in a turbine blade cooling technology field. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a blade for use in turbine with cooling structure of aircraft engine.
