Abstract (en)
[origin: EP1925808A2] The exchanger has a surface area, which is pressurized with a medium e.g. exhaust gas, where the surface area is made of metal e.g. aluminum or stainless steel, which is provided with coating. The coating is converted by high operating temperature into a corrosion resistant, partial ceramic e.g. oleophobic protective layer. The coating and/or protective layer has a catalytic acting additives, which are microencapsulated. An independent claim is also included for a method for producing the heat exchanger.
