The cap (100) has an air cap chamber (20) narrowed by an air cap body (10), where a flame jet (50) produced by high velocity oxy-fuel flame spraying is conducted via the chamber. A region (12) of the body facing the chamber is made of a material e.g. brass, copper, or copper-brass alloy, that is the...
