Abstract
The present disclosure is directed to an apparatus and method of sintering inorganic powder coatings on substrates, and includes a flame and an electric plasma. The method is capable of being used in an open atmospheric environment. The substrate is electrically conductive and is used as one electrode while the flame is used as the other electrode that is moved over the areas of the powder coating to be sintered. An electrical current is used to cause a plasma produced through the flame, resulting in a combined energy and temperature profile sufficient for inorganic powder-powder and powder-substrate bonding. This method is referred to as flame-assisted flash sintering” (FAFS).
