METHOD FOR PRODUCING EXHAUST PIPE

摘要

A method for producing an exhaust pipe includes electrocoating a surface of a metal base material with a paint to form a coat film. The paint includes inorganic glass particles and an electrocoating resin. The coat film is heated to a first temperature that is not lower than a burning-out temperature of the electrocoating resin. The coat film is heated, after heating the coat film to the first temperature, to a second temperature that is not lower than a softening point of the inorganic glass particles to produce the exhaust pipe which includes the metal base material and a surface coating layer formed on the surface of the metal base material.
