Abstract

PURPOSE: Abrasion resisting material for valve guide having A-type graphite, dense pearlite base ground and uniformly distributed granular V carbide, obtained by adding limited quantity of V to the base material of cast iron having a good lubricating capacity.
CONSTITUTION: 0.15W0.20% of V is added to the base material of cast iron regulated at about C;3.40W3.90%, Si;1.50W2.00%. Hereby, A-type graphite is deposited without carrying out heat treatment casting as it is and the material having dense peearlite base ground and high hardness granular V carbide distributed uniformly, is obtained. The above material is most suitable for that of for valve guide because it is excellent in lubricating capacity and abrasion resisting property.
