Title (EN) IRON BASED ALLOY
(FR) ALLIAGES À BASE DE FER
Abstract:
(EN) The present invention relates to alloy compositions for protecting or re-finishing industrial tools which will be or have been exposed to galling and abrasive wear during use. Wear arises as a result of the normal cutting or drilling or similar operations of the tool. Large industrial tools which suffer wear include drill strings used in the oil and gas industry and the present invention is concerned with providing materials to overcome or reduce such issues. The issue of wear at contacting surfaces in engineering applications in general is awidespread problem and the invention provides alloys to address this problem.The present invention also provides alloy compositions which can be used for forming welded joints.
(FR) La présente invention concerne des compositions d'alliage servant à protéger ou à ré-apprêter des outils industriels qui seront exposés ou qui ont été exposés au grippage ou à une usure abrasive lors de l'utilisation. L'usure est le résultat de la coupe normale ou du forage normal ou d'opérations similaires de l'outil. Les grands outils industriels soumis à une usure comprennent des trains de tiges de forage utilisés dans l'industrie pétrolière et gazière et la présente invention concerne la mise en œuvre de matériaux permettant de surmonter ou de réduire de tels problèmes. Le problème d'usure au niveau de surfaces de contact dans des applications d'ingénierie en général est un problème répandu et l'invention fournit des alliages pour résoudre ce problème. La présente invention concerne également des compositions d'alliage qui peuvent être utilisées pour former des joints soudés.
