Abstract
A coating composition for metal or refractories includes a polysilazane resin; and one or more additives that alter the thermal conductivity and/or the abrasion resistance of the cured polysilazane resin. The coating composition may be applied to a metal or refractory material substrate and heated to form a ceramic layer on the substrate. The ceramic layer exhibits lower thermal conductivity and increased abrasion resistance.
