Claim 1
Independent Claim
160 words
A METHOD OF FORMING A METAL OXIDE-COATING ON AN ARTICLE WHICH COMPRISES FORMING AND MAINTAINING A FLAME FROM A COMBUSTIBLE MIXTURE, THE COMBUSTIBLE PORTION OF SAID MIXTURE CONSISTING ESSENTIALLY OF OXYGEN AND A COMBUSIBLE METAL, THE OXIDE FORMED FROM SAID METAL MELTING ABOVE 1000*C. AND BEING CONDENSIBLE TO THE LIQUID STATE ABOVE 1300*C., ENTRAINING IN SAID FLAME REFRACTORY SEED PARTICLES, EACH 100 PARTS BY WEIGHT OF COMBINED METAL AND SEED PARTICLES COMPRISING AT LEAST 30 PARTS OF METAL AND AT LEAST 10 PARTS OF SEED PARTICLES, SAID METAL UPON BURNING YIELDING AVAILABLE HEAT AT THE MELTING POINT OF THE METAL OXIDE PRODUCED BY THE COMBUSTION OF THE METAL, AT LEAST EQUAL TO THE ENHALPY OF SAID OXIDE AT SAID MELTING POINT, SAID AVAILABLE HEAT COMPRISING AT LEAST 85% OF THE HEAT REQUISITE FOR THE COATING OPERATION, IMPINGING THE FLAME AGAINST THE ARTICLE TO FORM AN ADHERENT COATING CONTAINING BOTH THE SEED PARTICLES AND THE OXIDE FORMED IN BURNING THE METAL.
