Abstract (en)

A thermal spray powder is formed of a blend of particles of a polymeric powder and a mineral wherein the mineral particles, and preferably also the polymeric particles, each have a coating layer thereon approximately one monolayer thick. The layer is an organofunctional silane which includes an organofunctional group such as an amino propyltriethoxy. The silane is formed from a precursor silane having a hydrolyzable group bondable to the mineral constituent upon hydrolyzing of the hydrolyzable group. Desirably the mineral is silicon aluminum alloy and the polymeric powder is a poly(para-oxybenzoyl)ester.
