| Abstract | A novel powder modification method based on the simultaneous softening and agglomeration of steel powders via heat treatment in a rotary tube furnace has been investigated as a promising way to improve H13 tool steel powder cold sprayability. By adjusting starting powder size and shape as well as heat treatment conditions (maxi-mum temperature, cooling rate and heat treatment atmosphere), cold spray of H13 powder went from virtually no deposition to the production of dense, sound and thick deposits with a powder deposition efficiency of 70%. Powder agglomeration, surface state, microstructure evolution and softening are identified as key factors deter-mining the powder deposition efficiency and resulting deposit microstructure. |
