SiO_2-X Coated Articles by Chemical Vapor Deposition by Plasma and Coating Method

摘要

A coated stainless steel article and a method of preparing the article are disclosed. The coating is a plasma chemical vapor deposited coating, formed from a plasma of nitrous oxide, a silane, and an energy transfer agent (such as He, Ar). The resulting coating is adherent, corrosion resistant, and has a thickness sufficient to mask and cover the features of the stainless steel substrate, and to provide a pitting potential (in 3.5% NaCl) of greater than 600 millivolts, a J.I.S. 8502 (1982) versus a saturated calomel electrode a salt spray test rating in 5% NaCl-0.02% hydrogen peroxide of at least B.
