摘要： Provided is a method for forming a silicon oxycarbonitride film (SiOCN) with varying proportions of each element, using a disilane precursor under vapor deposition conditions, wherein the percent carbon incorporation into the SiOCN film may be varied between about 5 to about 60%, by utilizing co-reactants chosen from oxygen, ammonia, and nitrous oxide gas. The carbon-enriched SiOCN films thus formed may be converted to pure silicon dioxide films after an etch stop protocol by treatment with O2 plasma.

摘要： Provided are stainless steel for a separator of a polymer electrolyte membrane fuel cell, which exhibits enhanced hydrophilicity and enhanced corrosion resistance, and a method of manufacturing the same. In the stainless steel for a separator of a polymer electrolyte membrane fuel cell, which exhibits enhanced hydrophilicity and enhanced corrosion resistance, according to an embodiment of the present invention, a ratio of Cr hydroxide/Cr oxide included in a passivation film of the stainless steel ranges from 0.7 to 1.6, and the passivation film has a contact angle (θ) of 70° or less. Thus, not only corrosion resistance may be enhanced by removing a non-conductive film formed on a surface of the stainless steel and forming a new conductive film thereon, but hydrophilicity may also be secured without additional surface treatment such as a separate coating or the like, and thus manufacturing costs may be reduced and productivity may be increased.
