Static Immersion Tests of Corrosion-Resistant Steel Alloyed with Silver and Titanium: Ion Outflow

Abstract—Corrosion-resistant steel alloyed with silver and titanium to give it antibacterial properties for medical purposes is designed. Several compositions are investigated under static conditions by holding them in solutions with 1.68–9.18 pH for a long time. The metal concentration in the solution is determined by inductively coupled plasma atomic emission spectrometry. A nonlinear increase in the element concentration in the solutions in time is observed during prolonged holding of steel in different media. No obvious changes in the silver concentration depending on a sample, medium, and even the holding time are revealed: the element concentration in the solution is <0.001 mg/L.
