The most common method of surface treatment in electronics cooling is surface anodizing. Anodizing can be an environmentally safe electrochemical process that thickens and toughens the naturally occurring protective oxide layer on the surface of metal parts. Surface anodizing changes the microscopic texture of a metal, making the surface durable, corrosion and weather resistant. For electronics cooling, the advantages of surface anodizing are the dielectric isolation of the cooling components from their electronics environment, and the significant increase in their surface emissivity. Various protective benefits and aesthetically pleasing colors have extended the use of anodization to many industrial and commercial applications.
