Novel steam turbine blade

The utility model discloses a novel steam turbine blade. The novel steam turbine blade comprises a blade body, a blade root and a blade crest. The novel steam turbine blade is characterized in that the top of the blade body is connected with the blade crest, the bottom of the blade body is connected with the blade root through a connecting block, air vents and through holes are distributed in the blade body, each air vent is in trapezoidal, one end of each air vent is located in the end in the rotating direction of the blade, the other end of each air vent is connected into the corresponding through hole, each air vent becomes narrow gradually, and the surface of the blade body is coated with a layer of high-temperature and high-strength ceramic materials. According to the novel steam turbine blade, water corrosion of the blade can be prevented, rare metal is saved, cost is reduced, and the safety performance of the blade is guaranteed; meanwhile, the utilization rate of steam is increased, the power generation efficiency is improved, the reliability of a unit is improved, and the available rate of the unit is increased.
