Title (EN) METHOD OF CONTROLLING THE CORROSION RATE OF ALLOY PARTICLES, ALLOY PARTICLE WITH CONTROLLED CORROSION RATE, AND ARTICLES COMPRISING THE PARTICLE
(FR) PROCÉDÉ DE RÉGULATION DE LA VITESSE DE CORROSION DE PARTICULES D'ALLIAGE, PARTICULE D'ALLIAGE À VITESSE DE CORROSION RÉGULÉE ET ARTICLES COMPRENANT LADITE PARTICULE
Abstract:
(EN) A composite particle comprises a core, a shielding layer deposited on the core, and further comprises an interlayer region formed at an interface of the shielding layer and the core, the interlayer region having a reactivity less than that of the core, and the shielding layer having a reactivity less than that of the interlayer region, a metallic layer not identical to the shielding layer and deposited on the shielding layer, the metallic layer having a reactivity less than that of the core, and optionally, an adhesion metal layer deposited on the metallic layer, wherein the composite particles have a corrosion rate of about 0.1 to about 450 mg/cm2/hour using an aqueous 3 wt% KCl solution at 200°F. An article comprises composite particles, wherein has a corrosion rates of about 0.1 to about 450 mg/cm2/hour using an aqueous 3wt% KCl solution at 200°F.
(FR) Cette invention concerne une particule composite, comprenant un noyau, une couche de protection déposée sur le noyau, et comprenant en outre une zone de couche intermédiaire, formée à l'interface de la couche de protection et du noyau, la zone intermédiaire présentant une réactivité inférieure à celle du noyau et la couche de protection présentant une réactivité inférieure à celle de la zone intermédiaire. Ladite particule comprend en outre une couche métallique qui n'est pas identique à la couche de protection et déposée sur la couche de protection, la couche métallique présentant une réactivité inférieure à celle du noyau, et optionnellement, une couche métallique d'adhésion déposée sur la couche métallique. Les particules composites présentent une vitesse de corrosion d'environ 0,1 à environ 450 mg/cm2/heure dans une solution aqueuse de chlorure de potassium à 3 % en poids à 200˚ F. Un article selon l'invention comprend des particules composites présentant des vitesses de corrosion d'environ 0,1 à environ 450 mg/cm2/heure dans une solution aqueuse de chlorure de potassium à 3 % en poids à 200˚ F.
