A main goal in the manufacture of composite materials is the possibility of applying the colloidal approach to powder metallurgy. Here porous nickel coatings have been prepared in the inner walls of steel tubes by a simple, low‐cost colloidal process. Coatings treated at 650 °C show good adhesion to the steel surface and a higher porosity that bulk bodies, as desired for manufacturing inner linings on long steel tubes such as those used for heat‐exchange applications.
