Özet

Armor steels are widely used in both civilian and military applications, and they play an important role in

protecting infrastructure due to their capacity for defense against a variety of threats. Welding is a typical

method of joining armor steel plates in structures. The welding process affects the mechanical properties

and performance of steel. This study aims to research the corrosion and wear behavior of welded armor

steels, considering both the pre- and post-fatigue conditions. The effect of weld penetration rate, which

varies with welding parameters, on the fatigue, wear, hardness, and corrosion properties of steel is

investigated. To determine how fatigue affected corrosion and mechanical properties the specimens were

tested before and after the fatigue test. Hardness values ranging from 200 to 500 HV were recorded along

distinct hardness lines. Following the fatigue test, corrosion rates increased by 11%, 59%, and 49% for

three separate penetration rates, with a maximum of 0.296 mm/year. While all samples showed an increase

in specific wear rates following the fatigue test, the lowest result was 1.07 3 1024 mm3N21 m21 and the

highest was 1.84 3 1024 mm3N21 m21.
