Estudio tribológico de un recubrimiento bimodal WC-Co-VC aplicado por HVOF para trenes de aterrizaje. por Ospina Flórez, Juan Diego

“…De todas estas partes metálicas quizás la más propensa a la corrosión es el tren de aterrizaje debido al alto impacto de diferentes sustancias como lo son la tierra, el agua, la sal, la grava y demás desechos y contaminantes presentes en el ambiente. Debido a la necesidad de preservar estas superficies metálicas y conservar sus propiedades existen diferentes alternativas para lograr esta protección, ya sea con un adecuado diseño, una selección de materiales idóneos, modificando el medio donde se encuentra, mediante la creación de una aleación resistente a la corrosión, a través de protección anódicas o catódicas, o por medio de la adición de un recubrimiento superficial.…”
