<div>In this study, the nature of boriding surface treatment mechanism of the steel prestressing strand is evaluated and then the corrosion resistance of the borided steel in hydrochloric acid is assessed (detection of the content of released iron and manganese in the exposure solution). The effect on the bond strength of the treated steel prestressing strand with normal strength concrete is also evaluated (pull-out test). Boriding was carried out in a boron carbide backfill with fluoride activators. This manuscript describes the first informative results on this topic.</div>
