Claim 1
Independent Claim
112 words
A METHOD OF APPLYING A SURFACE COATING TO AN OBJECT WHICH COMPRISES INTRODUCING A SOLID COATING MATERIAL AND A FLUID COMBUSTIBLE MIXTURE UNDER PRESSURE INTO A CONFINED COMBUSTION SPACE, HEATING AT LEAST A PORTION OF THE COATING PARTICLES TO A HIGH TEMPERATURE BY BURNING THE FLUID COMBUSTIBLE MIXTURE IN SAID SPACE IN THE PRESENCE OF SUCH MATERIAL, AND THEREAFTER PROPELLING HEATED COATING PARTICLES TOWARD THE SURFACE OF THE OBJECT TO BE COATED AT A LINEAR VELOCITY GREATER THAN 500 FEET PER SECOND BY DISCHARGING THE PARTICLE-CARRYING BURNING GASES THROUGH A CONFINED PATH IN WHICH SUCH GASES ARE ACCELERATED TO AN EXIT VELOCITY SUFFICIENTLY HIGH TO IMPART SUCH LINEAR VELOCITY TO THE PARTICLES.
