Study of the Structure, Mechanical Characteristics, and Antibacterial Properties of Corrosion-Resistant Steel Alloyed with Silver and Titanium

A new medical antibacterial corrosion-resistant steel alloyed with silver and titanium was smelted. The optimal conditions for homogenizing annealing were selected to obtain a uniform structure and give rise to equiaxed grains. The mechanical properties, microstructure, and phase composition were studied. X-ray powder diffraction analysis showed that the steel without alloying elements after rolling has an austenitic structure. The alloying gave rise to a small amount of ferrite in the steel structure. Spectral analysis showed a uniform silver distribution throughout the alloy. It was determined that a steel sample containing silver and titanium has an antibacterial effect on the bacterial strain Pseudomonas marginalis .
