description | The present disclosure is related to a method for the thermal superficial treatment by plasma for the austenitic stainless steel; comprising the plasma heat treatment stage in a temperature range of 370°C to 430°C, for a time between half an hour and one hour, at a pressure of between 100 and 500 Pa, in a gaseous atmosphere based on low pressure Oxygen and Hydrogen, at a current density of 0.5 to 1.5 mA/cm2, promoting the formation of a superficial austenite layer consisting of hematite and magnetite iron oxides.
En vista de lo anteriormente descrito y con el propósito de dar solución a las limitantes encontradas, es objeto de la invención ofrecer un método de tratamiento térmico por plasma de un acero inoxidable austenítico, que comprende la etapa de tratamiento térmico por plasma en un rango de temperatura de 370°C a 430°C, durante un tiempo de 0.5 a 1 hr., a una presión de entre 100 a 500 Pa, en una atmósfera gaseosa de Oxígeno e Hidrógeno a baja presión, a una densidad de corriente de entre 0.5 a 1.5 mA/cm2, que promueve la formación de una capa austenita superficial constituida por óxidos de hierro tipo hematita y magnetita. |
