THE CORROSION TESTS OF AMORPHOUS-CARBON COATINGS DEPOSITED BY RF DENSE-PLASMA ONTO STEEL WITH DIFFERENT CHROMIUM CONTENTS

In the paper the results of experimental studies concerning characterization of amorphous carbon layers obtained by a new method of r.f. dense plasma CVD onto steel with different chromium contents are presented. Thin, amorphous carbon layers, deposited onto these substrates, are the subject of structural and physical investigations. This refers also to the system of carbon layer-steel substrate correlated with a microstructure of the layer, and to the determination of specifications resulting from the model for optimization of the synthesis and applicability of a new system as medical implants. Amorphous carbon coatings produced by the dense r.f CH4 plasma method from steel AISI-316L used in medicine were investigated to determine their suitability as biomaterials.
