“…This paper is focused on evaluation of laser heat treatment applied on the HVOF sprayed coatings of CoCrTaAlCSiY. Results of pin-on-disc wear test, SEM with EDX analysis and XRD analysis which are listed in this study complement wear and erosion tests reported in previous study [12]. The pin-on-disc test confirmed positive effect of laser heat treatment on COF and K which are in good agreement with results of linearly oscillating ball-on-flat wear test (ASTM G-133).…”

Superalloys with cobalt as a base material are widely used among different industry applications. Their main advantages are excellent corrosion and wear resistance. Material CoCrTaAlCSiY was chosen for this study as an unexplored representative of Co-based superalloys with a potential for good tribological behavior. This paper follows the results of previous paper called "Microstructure and Tribological Behavior of HVOF Sprayed and Laser Remelted CoCrTaAlCSiY Coatings". In this paper are also presented three states of HVOF sprayed and post laser treated coatings of CoCrTaAlCSiY (as spray state and two different laser treatments varying in specific energy of laser). Pin-on-disc test was carried out to evaluate wear behavior. XRD analysis was done to reveal phase transformations between FCC and HCP. A positive effect on wear coefficient for both laser treated CoCrTaAlCSiY coatings was proved.

“…Entre esas opciones, el uso de la radiación láser, posterior a la obtención de los recubrimientos mediante proyección térmica por flama, se ha reportado como una posibilidad muy atractiva para conseguir mejoras importantes en las propiedades de los recubrimientos. En trabajos como los reportados por (Fenineche, 2008;Glanc et al, 2018, González et al 2007, Karimi et al, 2016, Panziera et al,, 2020, Vuoristo et al, 2006,, se han empleado diferentes tecnologías de proyección térmica, tales como flama, plasma, alta velocidad, seguidas del uso de radiación láser e incluso también se ha utilizado como apoyo energético en los procesos conocidos como de Proyección en Frío (Cold Spray, por su denominación en inglés), (Olakanmi et al,, 2014).…”

En este trabajo, se presentan los resultados provenientes de la generación de recubrimientos base Níquel mediante proyección térmica por flama, seguidos de la aplicación de radiación láser, en diferentes condiciones, sobre un acero de bajo carbono. Los revestimientos logrados fueron caracterizados mediante microscopía electrónica de barrido y microanálisis, ensayos de microdureza, rugosidad y de polarización lineal, con el fin de caracterizar el efecto de la aplicación de la radiación láser en la resistencia a la corrosión de los recubrimientos previamente elaborados por proyección térmica, en un medio salino. Con la aplicación de la radiación láser se consiguió una mejora de la resistencia a la corrosión, asociada, principalmente a la disminución de la porosidad del recubrimiento generado mediante Proyección Térmica.
