Abstract
A process for substantially improving the heat transmission and reflection properties of anodized metals is presented along with a method of improving such properties while allowing for such processed anodized metals to be used for food contact.
Claims7
A method for preparing thermally transmissive anodizeable aluminum and aluminum alloy surfaces for receiving selected infrared radiation thereon, comprising
- (a) selecting a range of infrared thermal radiation;
- (b) providing a roughness gradient of at least ¼ wavelength of said selected range of infrared radiation on said surface;
- (c) anodizing said surface gradient to provide a porous oxide layer having thickness of from about 5μ to about 120μ;
- and
- (d) applying a thermally adsorptive dye to said porous oxide layer;
- and sealing said dyed oxide layer.
