Abstract
A process for applying a metallic sprayed coat to the inner surface of a metal hollow body includes heating the body to a temperature of over 150.degree. C. before coating and cooling the body through at least 50.degree. C. during the coating process. Positive shrinkage tensions are thereby created during the coating which act to improve adhesion in operation.
