Abstract:
1. An article comprising (a) a permanent substrate which at room temperature has a coefficient of thermal expansion in the range between −5.0×10 (b) a fine grained metallic coating extending over at least part of an inner and/or outer surface on the permanent substrate, having an average grain size between 2 and 1,000 nm, and a coefficient of thermal expansion in the range between −5.0×10 (c) said article exhibiting no delamination and the displacement of the coating relative to the underlying substrate is less than 2% after said article has been exposed to one temperature cycle consisting of exposure to liquid nitrogen for one minute followed by exposure to 90° C. hot water for one minute, or one temperature cycle according to ASTM B553-71 service condition 1, 2, 3 or 4; wherein said fine-grained metallic coating has a ductility ranging from 1 to 20%.
