Claims14
A coating composition for a heat exchanger tube comprising vanadium (V), a flux, and a binder,
- wherein the vanadium is included in an amount of 28 to 38 parts by weight with respect to 100 parts by weight of the coating composition.
A heat exchanger tube comprising:
- a metallic base material;
- and
- an anti-corrosive reinforcement layer famed on the metallic base material derived from a coating composition comprising vanadium (V), a flux, and a binder.
A coating method comprising:
- coating a surface of a metallic base material with a coating composition comprising vanadium (V), a flux, and a binder to form a coating layer;
- joining the metallic base material to the coating layer by brazing to form a brazed metallic base material;
- and
- heat-treating the brazed metallic base material to form an anti-corrosive reinforcement layer.
