Development of high efficiency solar collector plates. Progress report, January 1, 1975--May 31, 1975
Description:
Composite metal technology is used to manufacture intermetallic compound (IC) absorption surfaces and to combine them integrally with a composite metal tube-in-sheet collector plate. Heat treatment process for Al--Ni system was optimized and ..cap alpha.. greater than or equal to 0.95 and epsilon less than or equal to 0.3 were obtained over a broad range of compounding conditions. Studies by SEM show that the Al--Ni IC surface is porous, spongelike and the dimensions of its fine structure are o…
