SHOT-PEENING METHOD

Shot-peening method. Projecting a powder onto a surface. The powder includes sintered particles, more than 95 wt % of the particles are beads. The powder has, in wt % based on the oxides: -ZrO2 partially stabilized with CeO2 and Y2O3: balance to 100%, CeO2 and Y2O3 present, in mol % according to the...

Zusammenfassung:	Shot-peening method. Projecting a powder onto a surface. The powder includes sintered particles, more than 95 wt % of the particles are beads. The powder has, in wt % based on the oxides: -ZrO2 partially stabilized with CeO2 and Y2O3: balance to 100%, CeO2 and Y2O3 present, in mol % according to the sum of ZrO2, CeO2 and Y2O3, CeO2: 2.5-11 mol % and Y2O3: 0.5-2 mol %, -Al2O3; 3-50%-additive chosen from CaO, manganese oxides, ZnO, praseodymium oxides, SrO, copper oxides, 0.2-6% Nd2O3, BaO, iron oxides, and mixtures thereof: CaO being less than 2%, -elements other than ZrO2, CeO2, Y2O3, Al2O3, CaO, manganese oxides, ZnO, praseodymium oxides, ≤5% SrO, copper oxides, Nd2O3, BaO, and iron oxides: manganese oxides, praseodymium oxides, copper oxides and iron oxides being expressed as MnO, Pr6O11, CuO and Fe2O3, respectively, and a relative density greater than 95%.
