Résumé

In this part of the study, the comparative observations of the structure and the surface temperature of the frost layer of both the coated and uncoated surfaces are carried out and a preliminary analysis is presented. A series of the repeated cycling tests has been completed that lasted for more than 2 months, and the influences of the coating thickness are investigated. The results show that the frost layer deposited on the coating surface has a very fragile structure and can be removed easily by an external force. The coating thickness has an important effect on the anti-frosting performance of the paint. The results also show that the coating of the paint on the copper surface is durable and presents a very good repeated cycling performance. (See also this Bulletin, reference 2006-1243.)
