CORROSION PROPERTIES OF POROUS TITANIUM SINTERES WITH SODIUM CHLORIDE

Popis výsledku v původním jazyce

Materials for long term implants must be highly corrosion resistant. Corrosion resistance of surface is closely connected to biocompatibility of particular application. Surfaces of implants can also be treated for specific biological reaction of organism. The article is focused on corrosion properties of porous titanium with different level of porosity. This material was created by sintering titanium powder with different fraction of sodium chloride. Porous surface on implants from such material ensure high level of osteointegration of the implant into bone. The surface of the implant can be also treated additionally and this material is common for manufacturing of long term implants. Electrochemical corrosion behaviour of this material was tested and observed. Isotonic solution was used for these particular measurements. Open circuit (corrosion) potentials were found, corrosion rate and polarization resistance values were determined. Pitting potentials of depassivation and repassivation were also measured. Effect of porosity on corrosion properties was compared and discussed. Surfaces of samples were observed by light and electron microscopy before and after testing. EDS microanalysis were made on surface of tested samples and inside of corrosion pits.
