Abstract
The invention discloses a turbine blade air film hole precision forming method, and belongs to the field of rapid casting based on a photocuring forming technology. The turbine blade air film hole precision forming method comprises the following steps: 1) manufacturing a turbine blade resin mold by using the photocuring rapid forming technology; 2) pouring ceramic slurry into a resin mold prototype of a turbine blade through a gel casting method to obtain a casting mold blank body, so that forming of an air film hole ceramic core is realized; 3) further strengthening the air film hole ceramiccore through vacuum freeze drying and high-temperature sintering, so that forming of different ceramic-based air film hole ceramic cores is realized; and 4) for the air film hole ceramic cores with different types of ceramic bases, combining a directional solidification technology to realize air film hole casting forming of various high-temperature alloys, and finally removing the ceramic cores remained in a metal blade and an air film hole through a core removing process, so that high-quality forming of the cast air film hole is realized. The turbine blade air film hole precision forming method is reasonable in design and simple and convenient to operate, and can realize forming of the high-quality cast air film hole.
