Abstract

Nuevo tratamiento de nitruración en aleaciones Ni-Ti para su aplicación en medicina. Aplicación del tratamiento termoquímico superficial de nitruración gaseosa en aleaciones Ni-Ti caracterizado porque se consiguen aumentos en la resistencia al desgaste y disminución en el coeficiente de fricción tanto estáticos como dinámicos para su aplicación en campos médicos como: Odontología: Arcos de Ortodoncia, sistemas de prótesis removibles o fijas, implantes yuxtaóseos, distractores mandibulares, accesorios quirúrgicos y herramientas. Traumatología y Ortopedia : Bolas para las prótesis de cadera que estarán en contacto con el acetábulo, partes de las prótesis articulares en las que haya fricción, clavos o grapas de osteointegración, cáteters o tubos guías de endoscopias o para extracción de pólipos, corrección para sistemas de columna vertebral, correctores de malposiciones óseas. Cardiovascular: Stents, sistemas guía de circuito sanguíneos, filtros de sangre,... entre los más importantes.New nitriding treatment in Ni-Ti alloys for application in medicine. Application of the surface thermochemical treatment of gas nitriding in Ni-Ti alloys characterized in that increases in wear resistance and decrease in the coefficient of friction are achieved both static and dynamic for application in medical fields such as: Dentistry: Arches of Orthodontics, systems of removable or fixed prostheses, juxtaosseous implants, mandibular distractors, surgical accessories and tools. Traumatology and Orthopedics: Balls for hip prostheses that will be in contact with the acetabulum, parts of the joint prostheses where there is friction, osteointegration nails or staples, catheters or endoscopy guide tubes or for polyps extraction, correction for systems of spine, correctors of bone malpositions. Cardiovascular: Stents, blood circuit guidance systems, blood filters, ... among the most important.
