The role of modification processes in ledeburitic class cast steel tribological properties

The work focuses on tribological tests of G200CrNiMo4-3-3 cast steel in the state without modification as well as after modification with FeSi and FeB. The FeSi modification reduced the secondary cementite precipitation in the Widmanstätten p...
