PREPARATION METHOD FOR TESLA TURBINE DISC, AND TESLA TURBINE DISC

摘要

A preparation method for a Tesla turbine disc, and a Tesla turbine prepared with the method. The preparation method comprises: placing a carbon fiber in an electroplating pool of a nickel-containing electrolyte for electroplating; winding the electroplated carbon fiber on a core shaft to form a disc-shaped carbon fiber; heating the disc-shaped carbon fiber and the core shaft together to reach a melting point of nickel, so that the metal nickel is molten and adhered and then cooled to room temperature, thereby obtaining a nickel-based carbon fiber composite material of a Tesla turbine disc; removing the core shaft, and machining an exhaust hole on the nickel-based carbon fiber composite material of the Tesla turbine disc by means of mechanical machining; performing anodic oxidation on the surface of the nickel-based carbon fiber composite material; sintering a ceramic on the surface of the nickel-based carbon fiber composite material subjected to anodic oxidation to obtain a ceramic material of the Tesla turbine disc; and polishing by using a diamond grinding liquid, thereby obtaining the Tesla turbine disc.
