En este trabajo se caracterizó la microestructura, la adherencia y el coeficiente de desgate de recubrimientos de CuxAly depositados mediante proyección térmica sobre sustratos de latón. En el estudio se utilizaron como parámetros de evaluación la preparación superficial del sustrato y un recubrimiento intermedio que actúa como capa adhesiva. El análisis de la composición química se hizo mediante la fluorescencia de rayos X (FRX), el análisis estructural se realizó por medio de la difracción de rayos X (DRX) y la microscopía electrónica de transmisión (MET). La adherencia se determinó mediante los ensayos de rayado transversales, la respuesta mecánica se evaluó mediante la medición de la dureza Knoop y pruebas de desgaste abrasivo tres cuerpos y "Pin en disco".  Los resultados permitieron establecer que el recubrimiento sin capa adhesiva y preparada por granallado metálico puede ser utilizado en la recuperación de piezas debido a que presenta menor falla cohesiva.
In this work characterized the microstructure, adhesion and coefficient of wear of coatings of CuxAly deposited via thermal projection on brass substrates. In the study, the surface preparation of the substrate and an intermediate coating acting as an adhesive layer were used as evaluation parameters. The analysis of the chemical composition was done by X-ray fluorescence (FRX), structural analysis was performed by means of X-ray diffraction (XRD) and transmission electron microscopy (MET). Adhesion was determined by cross-hatching tests, the mechanical response was assessed by measuring the Knoop hardness and abrasive wear tests three bodies and "Pin on disk". The results permitted to establish that the coating without adhesive layer and prepared by metal blasting can be used in the recovery of pieces because it presents less cohesive failure.
