After the slurry is applied on the inside passage, the flow of a gas is generated in the passage to remove the excess slurry from the passage. The gas is atmospheric air or compressed air and the other gas can also be used. After the gas is passed through the passage, the slurry is dried to vaporize a liquid medium in the slurry to form the dried metal based coating film.
