Electrolytic polishing of corrosion-resistant metal stents

Nawrat G., Waś J., Gonet M., Simka W., Bold T.

Polish Journal of Chemical Technology

2003

Vol. 5, nr 3

65-68

The paper deals with investigations on the influence of the parameters of the electrochemical and chemical treatment of stents made of steel type 00H17N14M2A on their corrosion resistance in constitutional fluids. The influence of the chemical composition of baths used for their electrolytic polishing and chemical passivation on the quality of the surface of the stents and the working parameters of their final treatment were determined, as well as the resistance of polished and passivated stents to pitting corrosion in Tyrode's and chloride solutions.

Wpływ sposobu obróbki stali 00H17N14M2A na odporność implantów metalowych

Nawrat G., Bołd T., Korczyński A., Małachowski A., Zych-Romanów M.

In this paper results of investigation of the influence of electrochemical and chemical surface treatment of steel 00H17N14M2A suitable for implants used in osseous surgery and cardiology (coronary stents) on their resistance to pitting have been presented. Composition of baths in which good gloss and smoothness of surfaces and resistance to pitting have been achieved.
