Abstract (en)
Treating a metal surface, e.g. for cooking utensils, comprises: (i) forming a series of micro-cavities in the treated surface; (ii) partially applying a coating on the surface, e.g. PTFE; and (iii) smoothing the non coated surface by projecting small balls (7) on the surface. Also claimed is the manufacture of cooking utensils by treating a metal layer (1), providing a continuous coating (2) of PTFE on a first surface (1b) and a partial coating (3) which is decorative on the other surface (1a).
