摘要：

The effect of the surface structure on sliding wear, has been presented for a non-alloyed spheroidal-graphite cast iron. The materials tested were sand castings hardened by foundry methods using chills, bulk hardened by heat treatment or surface hardened through rapid solidification using gas tungsten arc welding (GTAW) surface remelting. The material of the surface refined by melting in an argon atmosphere exhibits the lowest intensity of frictional-wear. The effect of the loading force and sliding speed on the wear was determined for this material. The geometric structure of its surface is also analyzed. (C) 2002 Elsevier Science B.V.
