“…Las antorchas de rociado térmico por llama, en su mayoría, pueden ser adaptadas para usar diversas combinaciones de gases, con el fin de obtener una optimización de los costos y la calidad del recubrimiento. Los gases comúnmente usados son acetileno, propano, gas metil-acetileno-propadieno e hidrógeno, combinados conjuntamente con oxígeno [20]. El acetileno es el gas más utilizado en función de obtener temperaturas de llama más altas, además de tener bajo costo.…”

Los recubrimientos por rociado térmico sirven para mejorar características mecá-nicas, físicas y químicas, dando calidades superiores de funcionamiento a la superficie. La variedad de productos y capas que se pueden obtener por rociado térmico, son virtualmente ilimitadas. Las técnicas de rociado térmico son sistemas de combustión por llama, oxi-combustible de alta velocidad, detonación; sistemas de arco eléctrico, plasma con arco transferido y no transferido. Estos procesos son usados con éxito en el mundo desarrollado y vienen incrementando las inversiones industriales en este campo, y también es usado por instituciones de investigación para el desarrollo de nuevas aplicaciones y la evaluación de las propiedades físicas, químicas y mecánicas de estas capas protectoras. La protección y modificación de la superficie y sus propiedades, son una herramienta potente en la ingeniería moderna, en donde las nuevas aplicaciones de la tecnología de rociado térmico son una alternativa técnica, económica y competitiva para la industria.

ABSTRACTThermal spray coatings are helping to control and reduce superficial problems involving wear and corrosion. Thermal spray coatings are profitable and serve to improve mechanical, physical and chemical performance giving superior qualities to the surface. The variety of products and layers that can be obtained by thermal spraying is virtually limitless. The techniques of thermal spraying are combustion systems by flame spray, high velocity Oxi-fuel, detonation and electric arc systems, plasma spray with transferred and not transferred arc. These processes are used successfully in the developed world and are increasing industrial investment in this field, and are also used by research institutes to develop new applications and to evaluate the physical, chemical and mechanical properties of protective coatings. The protection and surface modification and their properties, are a powerful tool of modern engineering, where, new applications of thermal spray technology is an alternative technical, economic and competitive in industry, Also, it can improve processes productivity, helping to increase the functionality of parts working under severe conditions of wear.

“…Some studies have proved that the thin coating can be surface modified and strengthened by remelting to eliminate the layer structure of coating, reduce the porosity, and improve the interface bonding with the substrate [8], which are beneficial for improving the coating's performance [9] and prolonging the service life of the parts [10][11][12]. Unfortunately, little attention has been paid to the remelted of thick coatings.…”

e self-fluxing NiCrBSi coatings with 800 μm thickness were prepared on the surface of AISI1045 steel substrate by plasma spraying. And the remelted coating was obtained using by the tungsten inert gas (TIG) arc process. e microstructure, surface roughness, hardness, phase composition, and wear resistance of the sprayed coating and remelted coating were systematically investigated. e results demonstrate that TIG remelted treatment can significantly eliminate the microscopic defects in thick coating and improve its density. e surface roughness (Ra) of the remelted coating is only 18.9% of the sprayed coating. e hardness of the remelted coating is 26.8% higher than that of the sprayed coating. e main phases in the sprayed coating are changed from γ-Ni, Cr 7 C 3 , and Cr 2 B to γ-Ni, Cr 23 C 6 , CrB, Ni 3 B, and Fe 3 C. e wear mass loss of the remelted coating is only 17.1% of the sprayed coating. erefore, a Nibased thick coating with good wear resistance can be obtained by plasma spraying and remelted technique.
