N2 - A potential method to improve hardness and wear resistance of austenitic grade stainless steels -like AISI 316L -, is by nitride deposition via the hybrid precursor system chemical vapor deposition (HYSYCVD) method. However, as a prerequisite, it is essential to ascertain the effect of Si-F species on the superficial characteristics of the metallic substrate in the absence of nitrogen precursor. In this work, the effect of silicon fluoride species (SiF X(g)) on the superficial characteristics of mirror polished 316 L stainless steel has been investigated, varying argon flow rate (10 and 15 cm3/min), temperature (300, 500, 700 and 900°C), and time (30 and 90 min). Results show that the lowest level of gas flow rate prolongs the residence time of the SiFx species and consequently induces their interaction with the substrate, producing FeF2 and various oxides, depending on the test conditions. Also temperature significantly influences the type of oxide formed.
