Silane-parylene coating for improving corrosion resistance of stainless steel 316L implant material
2011 (English)In: Corrosion Science, ISSN 0010-938X, E-ISSN 1879-0496, Vol. 53, no 1, 296-301 p.Article in journal (Refereed) Published
The corrosion resistance of a two-layer polymer (silane + parylene) coating on implant stainless steel was investigated by microscopic observations and electrochemical measurements Long term exposure tests in Hanks solution revealed that the coating of 2 mu m can be successfully used for corrosion protection However the addition of H2O2 simulating the inflammatory response of human body environment causes a dramatic destruction of the protective coating Analysis of the experimental data in terms of circuit models enables proposing a deterioration mechanism OH radicals formed at the metal surface attack the polymer thus the deterioration starts from the metal/polymer interface and progress towards the outward surface.
