Abstract

Recubrimientos absorbentes para receptores solares centrales y procedimiento para la preparación in situ de dichos recubrimientos mediante el empleo de un equipo portátil de proyección por plasma en el que se deposita una primera capa metálica de anclaje, preferiblemente de Ni20Cr, y una capa de material cerámico o cermet en unas condiciones tales que permiten obtener recubrimientos altamente absorbente en el rango solar, con muy buen comportamiento mecánico y alta durabilidad. El procedimiento también requiere unas etapas previas de secado del material a depositar y preparación superficial del sustrato (superficie del receptor). La presente invención también se refiere a los recubrimientos así formados.Absorbent coatings for central solar receivers and process for the preparation in situ of said coatings by using a portable plasma projection equipment in which a first metal anchoring layer, preferably Ni20Cr, and a ceramic material layer are deposited or cermet in such conditions that allow to obtain highly absorbent coatings in the solar range, with very good mechanical behavior and high durability. The process also requires prior stages of drying the material to be deposited and surface preparation of the substrate (receiver surface). The present invention also relates to the coatings thus formed.
