Abstract
Wear resistance of deposited metal of the graphitised steel type in metal-on-metal friction without lubrication at room and elevated temperatures was investigated, and its heat resistance was evaluated. It was established that the as-deposited metal alloyed with 1.4-1.6 wt.% C and 1.5-2.0 wt.% Si contains the optimal amount of graphite inclusions is characterised by high wear resistance, and has a decreased friction coefficient in metal-on-metal sliding friction at room temperature.
