Abstract
L'invention concerne un procédé et un appareil de grenaillage de précontrainte, qui utilise le réglage de la couverture du grenaillage de précontrainte pour adapter une compression superficielle supérieure et une profondeur de compression comparable à un grenaillage classique de couverture intégrale, mais avec un écrouissage réduit, ce qui améliore la stabilité thermique et réduit le temps et le coût du grenaillage de précontrainte. Un mode préféré de l'invention met en oeuvre une contrainte résiduelle d'une cristallographie par rayons X et un taux d'écrouissage déterminés par élargissement des lignes pour établir le degré optimal de couverture pour un matériau donné et l'intensité du grenaillage de précontrainte.
