ID-Nova Warm Spray Process

ID-Nova Warm Spray Warm spray is the addition of non-reactive gases such as nitrogen, argon or carbon-dioxide into HVOF processes to reduce temperature and increase particle velocity.  Warm spray can be used to enhance coating properties by decreasing porosity and oxide content in metal coatings. The technique of adding ‘inert gas” to the combustion stream cause an increase in the number of gas molecules which increases the gas velocity for a given temperature. This provides another parameter to enhance coating properties. This paper with examine the coating properties of using different auxiliary gases with ID-Nova HVOF process.
