Summary:PURPOSE:To reduce the wear and tear of an aluminum alloy flame coating film by sequentially laminating and curing a sealing agent with permeability to the aluminum alloy flame coating film or the like and an epoxy resin or the like whose function as a sacrifice anode is not deteriorated on the surface of a heat exchanger panel made of an aluminum alloy material. CONSTITUTION:A protective film 5 on the surface of the heat exchanger panel of an open rack type carburetor includes a flame coating film 2 formed by flame coating aluminum alloy such as Al-Zn alloy on the surface 1 of a base metal made of an aluminum alloy material of the heat exchanger panel. Then, an achromatic and transparent or little pigment including a sealing agent 3 which has permeability to the flame coating alloy film 2 is applied to the film 2 and cured. Thus, pores in the flame coating film 2 are closed so that the film is integrated with the agent and strengthened. Further, a surface layer resin 4 of an epoxy resin or urethane resin is applied to the sealing agent 3 and cured so that the function of the flame coating film 2 as a sacrifice anode is not deteriorated. Thus, excellent sea-water resistance, cold resistance and abrasion resistance are obtained.
