Title: Corrosion Properties of High Velocity Arc Sprayed FeAlCrNi/Cr_3C_2 Composite Coating
Abstract: Hot salt corrosion method was used to analysis the corrosion properties of high velocity arc sprayed(HVAS) FeAlCrNi/Cr_3C_2 composite coatings,corrosion surface and cross sectional images and composites of coatings were analyzed by SEM,TEM and XRD.The results show that the coatings have typical layer structures and relatively good mechanical properties.The corrosion rates show the parabola changes with the increase of corrosion time;and corrosion rate increases slightly with increasing temperature.There are oxides and sulfides on the corrosion surface;the corrosion resistance mechanism is inner-oxidation.
