In order to achieve a non-stick surface which is significantly harder wearing than hitherto, metal surface a is sand or shot blast and stainless steel or molybdenum is applied thereto so as to cover not less than 65% and not more than 90% thereof and provide a pervious intermediate substrate b having a micro-crenellated surface. Thereafter, a primer coat is applied to penetrate pervious layer b and finally a top coat, consisting primarily of a nonstick agent c, such as P.T.F.E, is applied so as to form a matrix of stainless steel or molybdenum impregnated with and covered by the non-stick agent. |
