To confirm the possibility of aluminum use on PHE plate for ocean thermal energy conversion (OTEC), the corrosivity and heat transfer tests using PEEK resin and WIN KOTE film coated aluminum blocks under ammonia or ammonia/water environment were performed. These coated blocks were immersed ammonia or ammonia/water during 2 months at saturated pool boiling condition. After these immersing test, these heat surface conditions were not or slightly changed, and these heat transfer coefficients were not also changed during 2 months. Then, it is found that these aluminum coating methods are available for using ammonia boiling environments such as PHE of OTEC.
