Abstract : The patent relates to a chromium coating and in particular to a coating having visual camouflage properties and a low emittance of light in the infrared range. The previous camouflage coating for use on naval vessels has been a grey paint having a dull or matte finish to inhibit visual discovery of the vessel. In modern warfare infrared detection techniques have become highly developed and the development of infrared counter-measures has become necessary. The invention provides a stable chromium plating for metal surfaces and a method for applying the plating. The plating is applied using a plating bath having a high acid content which is maintained at a temperature between 40C and 55C and is applied to a surface by an electroplating method using relatively high current densities.
