Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
150 words
A COATING METHOD WHICH COMPRISES PROVIDING A SOLUTION IN WATER OF AN OXYGEN CONTAINING SUBSTANTIALLY UNSOLVATED METAL SALT THAT IS THERMALLY DECOMPOSIBLE AT 400-600* F. TO YIELD DIRECTLY A REFRACTORY METAL OXIDE, THE METAL OXIDE CONTENT OF SAID SOLUTION BEING 0.1-10%, ATOMIZING THE SOLUTION, AND DIRECTING THE ATOMIZED SOLUTION AGAINST A SURFACE HAVING A TEMPERATURE OF 400-600* F. WHICH IS HOT ENOUGH TO THERMALLY DECOMPOSE THE COMPOUND TO RELEASE THE REFRACTORY METAL OXIDE PARTICLES IN DISCRETE FORM TO CONTACT AND ADHERE TO THE SURFACE AND TO VOLATILIZE THE REMAINING VOLATILE COMPONENTS WITHIN THE TIME PERIOD FROM JUST PRIOR TO CONTACT BETWEEN THE PARTICLES AND THE SURFACE TO SUBSTANTIALLY THE INSTANT OF CONTACT BETWEEN THE PARTICLES AND THE SURFACE, WHEREBY THE PARTICLES OF REFRACTORY METAL OXIDE RETAIN THE SOLID FORM AFTER DECOMPOSITION OF THE METAL COMPOUND AND WHILE RETAINED ON THE SURFACE SO AS TO PROVIDE A COATING ON SAID SURFACE.
