Abstract

L'invention concerne un nouveau procédé de trempe de pièces métalliques destinées à diminuer les contraintes nées de la trempe sans affecter les caractéristiques de façon sensible. Ce procédé consiste à tremper les pièces par immersion dans une suspension dans l'eau d'un produit liant de type argile et d'une charge minérale telle que magnétite, ferrosilicium, baryte. Des additions de produits inhibiteurs de corrosion, antimoussants ou antifloculants peuvent être faites à cette suspension. L'invention s'applique aux pièces métalliques, mais plus particulièrement aux pièces en alliages d'aluminium à haute résistance que leur forme ou leur dimension rend sujettes aux défauts provoqués par des contraintes de trempe excessives.
