Abstract
Abstract A flame spray process and a powder composition for use therein consisting of alumina particles having 1 to 50 percent by volume of titanium dioxide bonded to the surface thereof in which said alumina particles have a particle size between about +5 microns and -100 mesh and in which said titanium dioxide is in the form of particles having a particle size of -10 microns bonded to the alumina particles with a bonding agent which is substantially decomposed or volatilized during the flame spray process.
