“…As mentioned by other authors [3], as the temperature increases, the COF decreases while the wear of the tool increases. In order to verify if the wear increase is related to the thermal softening (tempering) of the tool steels, the hardness of the disks tested at 200°C was checked on the wear tracks, and no variations from the initial values were found.…”

“…Since hot stamping tools are subjected to high temperatures, the wear of tool steels and the prevailing wear mechanisms have been studied in detail [2,3]. Several authors have also studied wear behaviour in friction processes using specific tribological tests, in order to characterize different tool steel grades, with and without coatings, at elevated temperatures [3][4][5].…”

e aim of this work is to investigate the durability of tool steels for hot stamping by comparing the wear resistance of three hot work tool steels. Friction and wear behaviours of different tool steels sliding against a 22MnB5 uncoated steel at elevated temperatures were investigated using a high-temperature version of the Optimol SRV reciprocating friction and wear tester at temperatures of 40 and 200°C. Our results show that friction decreased with increasing temperature, whereas wear of the tool steel increased with temperature for the second and the third tested tool steels. e slightly better wear behaviour of steel specimen 1 comes from the hardness of the carbides in the martensitic microstructure, which are rich in vanadium.

“…In the following Raman spectra (Figure 9a), Fe2O3, resulting from the oxidation of Fe and Cr in the matrix, can be detected on the worn surfaces of all samples. The generation of Fe2O3 is expected to contribute to the lubricating effect [23,26,27]. Ag2O and MoO3 can be found on the worn surfaces, respectively, of A and M. In addition, the Ag2MoO4 phase is detected on the worn surface after the sliding process of AM.…”

Friction and Wear Behavior of an Ag–Mo Co-Implanted GH4169 Alloy via Ion-Beam-Assisted Bombardment

Ag, Mo, and Ag-Mo were respectively implanted into GH4169 alloy substrates without heating via ion-beam-assisted bombardment technology (IBAB). In addition, the wear performance under low sliding speed and applied load were researched at room temperature (RT). A small amount silver molybdate phase could be detected on the surface of the co-implanted GH4169 alloy bombarded by a high-energy ion beam. The average friction coefficients under the steady wear state had almost no change at all. Compared with the un-implanted GH4169 alloys, the wear rate of the GH4169 alloys with co-implantation of Ag and Mo was reduced by 75%. A large amount of the silver molybdate phase could be generated due to the tribo-reaction on the worn surface during sliding. It benefits the formation of continuous oxide layers as lubrication and protected layers, leading to the change in the predominant wear mechanism from abrasion and adhesion wear to oxidation wear.

This study had investigated the main degradation mechanism of a roll in hot rolling process, to reduce the wear and oxidation, a type of low-melting glass fabricated by the fuse-polymerisation method was tested as a hot metal forming lubricant by a ball-on-disc tribometer at high temperature. The resultsrevealed that the roll degrades mainly due to the cracks initiated at the interface of carbides/matrix on the roll surface, then propagate along the interface, and being sheared off when the cracks confluence in the subsurface. The highspeed steel (HSS) starts to be oxidised at 500 C, and grows heavily with increasing temperature. The recommended lubricant presented a desired lubrication behaviour for hot rolling process that generating a higher friction coefficient at low temperature and a lower one at high temperature. The friction coefficient, wear rate, and oxidation of HSS roll was reduced materially, which meets the requirements of hot rolling lubricant well.
