چکیده
This study analyzes the influence of boron in presence chromium, vanadium, and titanium on changes tribological properties low-alloy casting steels caused by structural modifications brought about above elements. Eight grades cast were manufactured based designed chemical composition. The wear behavior these materials was investigated with GOST (Russian) standard test equipment, which steel samples worn coarse alumina particles (grit size #90). evaluated weight loss their mechanisms scanning electron microscopy. two predominant abrasive for microploughing microcutting. surfaces also showed traces pitting originating from removal larger particles. results obtained during wheel–rubber laboratory may be used to compare resistance a ferrite–pearlite microstructure because is sensitive abrasion microstructural due alloying additives non-heat-treated steels.
