extrusion die. the tested surfaces include hot work tool steel, coated with tin, crn, (ti,al)n and tib , respectively. to simulate the extruded material an aluminium cylinder heated to °c is used as counter body in a block-on-ring configuration. for comparison, the tool steel was also tested in uncoated
, hardness, thickness and intrinsic stress. it is shown that coatings of crn, and especially (ti,al)n and tib have the potential to effectively reduce the wear in extrusion dies. these coatings are mechanically, thermally and chemically stable when sliding against hot aluminium, in contrast with uncoated...
