HIGH-STRENGTH ALLOYED ANTIFRICTION CAST IRON Russian patent published in 2017 - IPC C22C37/10 

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy, namely to high-strength structural alloyed cast iron for cast parts of motors with enhanced antifriction and other special properties, not subject to thermal treatment and operating under friction conditions in gases. High-strength alloyed antifriction cast iron contains, wt %: carbon 3.1-3.6; silicon 2.0-2.5; manganese 0.8-1.2; nickel 0.7-1.5; molybdenum 0.2-0.4; copper 0.6-1.5; chrome 0.02-0.06; magnesium 0.02-0.03; cerium 0.03-0.05; vanadium 0.07-0.55; titanium 0.3-0.22; barium 0.03-0.06; boron 0.01-0.03; the rest is iron.

EFFECT: enhanced antifriction properties, endurance limit and wear resistance of cast iron.
