Co-Al permeating furnace device for hollow turbine blade of combustion gas turbine

The invention discloses a Co-Al permeating furnace device for a hollow turbine blade of a combustion gas turbine. The Co-Al permeating furnace device mainly comprises a heating furnace body, an electrical heating element, a furnace lid, a furnace pot, a vacuum-pumping system, a temperature control system, a thermocouple and the like. The Co-Al permeating furnace device has the beneficial effects that a Co-Al permeating method of the Co-Al permeating furnace device belongs to a gas-phase metal diffusion process, and adopts a one-step diffusion method; and the basic principle is as follows: a diffusion metal is activated through an activating agent such as a halogen or a halogen compound, is deposited on the metal surface under a vacuum or protective atmosphere condition, and reacts with matrix alloy to diffuse, so as to form a diffused metal or compound.
