PROTECTIVE MASK TO PROCESS TURBOMACHINE VANE SURFACES

摘要

FIELD: mechanics. ^ SUBSTANCE: proposed mask is intended for vane sandblasting and metal coating. It represents at least one part repeating the shape of root or shroud platforms and has orifices to allow access to surfaces to be processed. Aforesaid orifices feature the shape adapted to the said surfaces and have walls perpendicular to the latter so that particles reaching the mask cannot be rejected onto processed surfaces. Detachable and repeatedly used mask resists surface processing materials and conditions. ^ EFFECT: higher quality and efficiency. ^ 8 cl, 6 dwg
