Abstract

The present invention provides a process for applying a diffusion coating to steel coin blanks. The process comprises the steps of (i) charging a metallising reactor with a plurality of coin blanks and a chromising compound comprising ferrochromium granules, an energiser and a refractive diluent, (ii) heating the chromising compound to generate a chromising vapour for deposition on to the coin blanks, and (iii) removing the coin blanks from the reactor. The reactor rotates at a rate of 0.5-50 rpm. A process for preparing coins is also disclosed.
