| description | According to the method for chemical vapor deposition of the Al coating of the turbine blade, the formed Al coating is free of impurities and uniform in coating. Wherein raw materials of the internal generator and the external generator are high-purity Al particles, HCl gas introduced into the external generator is used as reaction gas, Ar is introduced as carrier gas, a reaction product is gas-phase AlCl3, the gas-phase AlCl3 is introduced into the internal generator to react to generate gas-phase AlCl, the gas-phase AlCl enters the reaction cover to generate an Al-seeping coating, and finally the Al-seeping coating is put into a vacuum treatment furnace to be subjected to diffusion heat treatment to finish processing. By adopting the chemical vapor deposition Al coating method disclosed by the invention, the infiltrated layers on the outer surface and the inner cavity of the blade are uniform, and no impurities or impurity particles exist in the infiltrated layers.
