Patent CA-2892216-A1 (CA)
Inventor: ROBERTS THOMAS R
IPC: C23C30/00
Filed: 2013-11-27
Abstract: The present invention provides methods for preparing or repairing a chemically-resistant coating such as a porcelain enamel on a metal substrate. One such method involves forming a softened ground coat on the substrate by heating to or maintaining an elevated temperature, followed by flame-spray depositing a coating material onto the softened ground coat. Then, the substrate is allowed to cool slowly so the chemically-resistant coating can form with less stress. Optionally, an induction coil is used to heat the substrate, both to form the softened ground coat and to slow the cooling of the substrate. Such methods allow for easier and faster repairs, and even in situ repairs of articles such as chemical reactor vessels, covers, baffles, thermowells, agitators, agitator shafts, pipes, heat exchangers, and storage tanks. Articles having a chemically-resistant coating also form a part of the invention.
