Abstract
Shot-peening powder that has ceramic particles. The powder having more than 95% by mass of beads. The beads having a median size D50 greater than 50 μm and less than 1200 μm, and having a value (D90−D10)/D50, or “S”, such that S≤−0.126·ln(D50)+0.980.
Claims17
A shot-peening powder consisting of ceramic particles, comprising more than 95% by mass of beads with a sphericity greater than or equal to 0.75,
- having a median size D50 greater than 50 μm and less than 1200 μm, and
- having a value (D90−D10)/D50, or “S”, such that
- S≤−0.126·ln(D50)+0.980 (1)
- D10, D50 and D90 being particle sizes corresponding to the percentages equal to 10%, 50% and 90% by volume, respectively, on the cumulative particle size distribution curve of the powder, said particle sizes being ranked in ascending order and being expressed in μm.
