Abstract
A composite metal of aluminum and nickel is used to form an economical solar absorption surface for a collector plate wherein an intermetallic compound of the aluminum and nickel provides a surface morphology with high absorptance and relatively low infrared emittance along with good durability.
Claims4
In a solar collector plate having a core and an absorption surface thereon, the improvement comprising said surface being made from an intermetallic compound of aluminum and nickel and formed by joining layer of aluminum and a layer of nickel which is at least 66 percent as thick as said aluminum layer and heating said joined layers to a temperature between 1000.degree. F and 1550.degree. for a period of 5 minutes to one hour, said intermetallic compound having a sponge like surface morphology which results in high absorptance and low infrared emittance values.
