説明

A study on the pitting resistance of white cast iron containing 1.1-2.8%C, which was cast or forged, was carried out by performing experiments using an Amslar-type wear testing machine under sliding conditions with light oil as a lubricant.<br>The results obtained are summarized as follows:<br>(1) Pitting resistance of white cast iron which contains higher carbon (C>1.8%) is significantly improved by forging.<br>(2) The most hardened layer generated by repeating contact stresses exists in 0.10∼0.20mm below the contact surface. The higher the contact stress is, the more the hardness increment of the hardened layer is.<br>(3) It seems that the propagation of crack is strikingly affected by the shape of large-size carbide and the adhesive strength between carbide and matrix.
