Abstract

In this study, up to 38ppm of boron was added to 4140 steel and the effects of this addition on microstructure and tribocorrosion were investigated. Tribocorrosion behavior was investigated in a 3.5% NaCl solution with a pin on disc method. As a result of the studies, it was found that the hardness and tribocorrosion behavior increased with the addition of boron but these values decreased with the increase in boron amount after 17ppm.
