Title
(EN) METHOD TO PRODUCE HIGH CORROSION AND WEAR RESISTANT CAST IRON COMPONENTS BY USING LASER CLADDING
(FR) PROCÉDÉ DE PRODUCTION DE COMPOSANTS EN FONTE HAUTEMENT RÉSISTANTS À LA CORROSION ET À L'USURE À L'AIDE D'UNE GAINE LASER
Abstract
(EN) The present invention relates to a method to produce a wear and corrosion resistant coating system onto a surface of a substrate, preferably a brake disc, the substrate or at least said surface of the substrate being made of a substrate material of the type iron-based material or steel material, said coating system comprising one or more coating layers, wherein the method comprises following steps: (1) Providing the substrate having the surface to be coated with the coating system, (2) Selecting a dedicated material for producing one or more coating layers of the coating system, (3) Producing onto the substrate surface to be coated one or more coating layers of the coating system by using a laser cladding process, wherein the dedicated material selected in step (2) is used as source material for the production of the coating layers, wherein for conducting step (3) a laser beam is positioned with respect to the substrate surface to be coated in such a manner that an angle between the laser beam and the substrate surface to be coated formed, and this angle called coating angle is maintaining during the production of the one or more coating layers at a value between 10° and 30°.
(FR) La présente invention concerne un procédé permettant de produire un système de revêtement résistant à l'usure et à la corrosion sur une surface d'un substrat, de préférence un disque de frein, le substrat ou au moins ladite surface du substrat étant constitué d'un matériau de substrat du type matériau à base de fer ou matériau d'acier, ledit système de revêtement comprenant une ou plusieurs couches de revêtement, le procédé comprenant les étapes suivantes : (1) fournir le substrat ayant la surface à revêtir avec le système de revêtement, (2) sélectionner un matériau dédié pour produire une ou plusieurs couches de revêtement du système de revêtement, (3) produire sur la surface de substrat à revêtir une ou plusieurs couches de revêtement du système de revêtement à l'aide d'un procédé de placage au laser, le matériau dédié sélectionné dans l'étape (2) étant utilisé comme matériau source pour la production des couches de revêtement, pour la réalisation de l'étape (3), un faisceau laser étant positionné par rapport à la surface de substrat à revêtir de telle manière qu'un angle entre le faisceau laser et la surface de substrat à revêtir soit formé, et cet angle appelé angle de revêtement se maintenant pendant la production de la ou des couches de revêtement à une valeur comprise entre 10° et 30°.
