Wear resistance of high-strength cast iron and steel 45 paired with alloy ASM in dry and boundary sliding friction

Conclusions

• 1. Cast iron subjected to treatments 3 and 4, and steel 45 subjected to induction hardening, have a higher tendency to galling when paired with alloy ASM than cast iron subjected to treatment 2 under conditions of dry friction.

• 2. Boundary friction tests showed severe galling of steel 45-ASM pairs under pressures of 75 and 100 kg/cm².

• 3. The tendency to galling is smallest for the cast iron subjected to treatment 2 and largest for the cast iron subjected to treatment 4. We recommend double normalization and alloying with copper as effective methods of reducing the tendency to galling of high-strength cast iron and of improving the wear resistance.
