Abstract
A method of manufacturing a high temperature heat exchanger that includes providing a heat exchanger made of at least one of nickel and a nickel metal alloy, applying a silicone aluminum coating to the heat exchanger, drying the silicone aluminum coating at a first temperature for a first time period, and curing the silicone aluminum coating at a second temperature for a second time period, such that a ceramic coating is formed.
