  • Characterization of the laboratory tool wear in hot extrusion of aluminium
    Terčelj, Milan ; Turk, Radomir ; Cvahte, Peter
    Laboratory testing of wear of the extrusion tools is much cheaper than direct determination of wear on true tools during the industrial operation. Its efficiency is expressed mainly as the control of ... influential parameters of the tribologic system, the way of mechanical loading, and the reduction of time needed for the estimation of tool life. In order to bring our testing conditions near to true physical characteristics of the hot extrusion process and to intensify (shorten) the process of wear analysis, a test named "block on disc" was developed and appled to simulate true tribologic system during the hot extrusion of aluminium. The tool was nitrided and tested in the new developed equipment at different testing conditions. Wear volume depended on the aluminium temperature and norme force. Time needed to reach sufficiently high wear relatively short in comparison to other wear test.
