Esta invención se refiere a un método, sistema y aparato para revestir una superficie de artículos sujetos a desgaste corrosivo, erosivo o abrasivo, tal como herramientas de impacto o abrasivas. El método incluye proporcionar un suministro de materia prima y alimentar la materia prima hacia una parte de la superficie del artículo a través de una fuente de alimentación dedicada. Una fuente de calor dedicada calienta la materia prima alimentada y la parte de la superficie del artículo de manera que la materia prima calentada y la parte de la superficie se fundan al menos parcialmente. Tras la eliminación del calor, la materia prima fundida y la parte de la superficie forman una capa de revestimiento unida sobre al menos una parte de la superficie del artículo, protegiendo así esa parte del conjunto contra el desgaste. (Traducción automática con Google Translate, sin valor legal) This invention relates to a method, system and apparatus for cladding a surface of an articles subject to corrosive, erosive or abrasive wear, such as impact or grinding tools. The method includes providing a supply of stock material and feeding the stock material towards a portion of the surface of the article via a dedicated feed source. A dedicated heat source heats the fed stock material and the portion of the surface of the article such that the heated stock material and the portion of the surface at least partially melt. Upon removal of the heat, the molten feedstock and the surface portion form a bonded coating layer on at least a portion of the surface of the article, thereby protecting that part of the assembly against wear.
