Friction and wear in hot forging of steels

Characterisation of different lubricants concerning the friction coefficient in forging of AA2618

“…2(c)). Lately, two different research teams (Ngaile et al, 2007;Daouben et al, 2007) evaluated lubricants by performing a sliding-upsetting test where relative motion is applied on an indenter penetrating a cylindrical billet ( Fig. 2(d)).…”

Effects of lubricant and lubrication parameters on friction during hot steel forging

“…Three parameters are defined: the lubrication index Li, the contactor roughness Ra and the critical length Lc [3].…”

Experimental simulation of strip edge cracking in steel rolling sequences

“…Daouben et al (2007) achieved an analysis of the lubricant effect on scratch occurrence on the surface of hot formed parts. In processes with roll-strip contact, the simulation test designed by Dubar et al (2006) allowed to perform a reliable predictive study of zinc fines formation during the skin-pass process.…”
