COVER HAVING A WEAR-RESISTANT SURFACE AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a cover (10) made of cast iron, comprising at least one traffic surface (20, 16), wherein the traffic surface has a wearing surface (30) formed by means of chilling the cast iron into white iron at least in some sections. The Brinell hardness of the wearing surface is preferably greater than 275 HBW and less than 350 HBW. The invention further relates to a method for producing a cover (10) from cast iron, wherein at least one shaped body is produced. Subsequently, an activation layer (50) is formed in the shaped body. Cast iron is filled in such that it chills at least partially as white iron on a contact surface (60) of the activation layer (50).
