MARULANDA AREVALO, José Luddey; TRISTANCHO REYES, José Luis  e  GONZALES B, Héctor Álvaro. The technology against the wearing is the thermal spray. Prospect. [online]. 2014, vol.12, n.1, pp.70-78. ISSN 1692-8261.  https://doi.org/10.15665/rp.v12i1.153.

Thermal 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.
