Effect of the concentrated heat flow treatment on the structure and the antiwear properties of cast iron
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 2
Abstract
The influence of modes of surface fusion by electric arc plasma (GTAW method) on the hardness and wear-resistance of plain cast iron was studied. A possible mechanism of structural rearrangement in the processed material during the friction was analyzed. This mechanism is determined by specific behaviour of hardened martensitic structure under dynamic load. This martensitic structure forms a metal basis of cementite eutectic under conditions of fast crystallisation.

Mechanism of carbon influence on the transition from graphite to cementite eutectic in cast iron
In this work an analytical solution is used to explain mechanism of carbon influence on the transition from graphite to cementite eutectic in cast iron. It is found that this transition can be related to (1) the nucleati...
