Zusammenfassung: | The method involves treating localized and partial laser, without covering all the surface. A specific number of parallel sweepings formed in an angle are determined with the generating cylinder. The sweepings are separated from each other at a definite distance, and functions proportionally for recasting the surface. The process combines the properties of the layers projected by the plasma and the layers are recasted with laser in the lubricated contacts.

Procedimiento de mallado con láser de recubrimientos previamente depositados por plasma sobre piezas cilíndricas basado en un tratamiento con el láser localizado y parcial, sin cubrir toda la superficie. Para ello se realizan ¿n¿ barridos paralelos que forman un ángulo determinado con la generatriz del cilindro y están separados entre sí una distancia determinada, función del porcentaje de la superficie a refundir. Puede realizarse una sola pasada con el láser (mallado paralelo IMG), o dos (mallado cruzado IMG). En los contactos lubricados este procedimiento combina las propiedades de las capas proyectadas por plasma y las capas totalmente refundidas con láser. Su aplicación es reducir la problemática debida al desgaste producido en los pares cinemáticos entre ejes o árboles y sus apoyos, presentes en la mayoría de las máquinas. |
