“…Schwingenschlögl et al (Schwingenschlögl, Niederhofer and Merklein 2019) observed lower amount of wear for increased velocity (30-120 mm/s) due more time to growth adhesive junctions and the experimental set-up. (Mozgovoy 2014) and Vilaesca et al (Vilaseca, Pujante and Casellas, et al 2014).…”

“…Schwingenschlögl et al (Schwingenschlögl, Niederhofer and Merklein 2019) observes lower amount of adhesive wear for increased tool hardness, which is most likely due to decreased elastic deformation of the tool asperities which results in a decreased real contact area. The two tool steels (1.2383 and 1.2367) investigated shows only marginal difference in wear behaviour.…”

“…Therefore, it is necessary to have in-depth knowledge of the friction and wear mechanisms and furthermore the effect of several parameters such as temperature and pressure. Many empirical results are available in the literature as regards the temperature and pressure effects on friction and wear mechanism during hot stamping (Dohda, et al 2015), (Ghiotti, Bruschi and Borsetto 2011), (Schwingenschlögl, Niederhofer and Merklein 2019); however, so far, the underlying friction mechanisms are not clearly explained. In most studies, the analyses are limited mainly to the tool and little attention has been devoted to the sheet metal surface (Pujante, Pelcastre, et al 2013), (Boher, Le Roux and Dessain 2012).…”

“…A relatively small impact on the adhesive wear is observed between newly developed high State of the Art thermal conductivity hot work tool steels (DIN 1.2383) with a reference tool steel (DIN 1.2367). (Schwingenschlögl, Niederhofer and Merklein 2019). The cast steel material GP4M is also used in investigations and in the hot stamping industry (Merklein, Stoehr, et al 2011).…”

“…This effect is contradictory to Archard's formula and expectations. Schwingenschlögl et al (Schwingenschlögl, Niederhofer and Merklein 2019) explain this by the reduced temperature in the contact zone due to increased heat dissipation. Merklein et al (Merklein, Wieland and Fell 2014) suggest that not all wear particles are transferred onto the tool.…”

In order to improve the wear resistance of ductile iron, different contents of TiC particles are added into ductile iron used lost foam casting and the tribological behavior of ductile iron is studied through a ballon-disk sliding test. It is found that with the increase of TiC content, the pearlite content gradually increases, which is attributed to TiC accelerating the diffusion of carbon atoms to cementite and promoting the heterogeneous nucleation of cementite. The increase of pearlite content and the second phase strengthening caused by TiC improve the hardness and tensile strength of ductile iron. Ductile iron has the best tensile strength (498 MPa) and hardness (168 HV1) with a TiC content of 1 wt.%. The wear resistance also increases with increasing TiC content. The wear volume is reduced from 0.14 mm 3 to 0.03 mm 3 , and the main wear mechanism changes from adhesive wear to abrasive wear. The oxide layer produced by frictional heat on the worn surface and the hardened layer produced by strain hardening on the subsurface further improve the wear resistance. Therefore, the wear resistance of ductile iron is affected by the changes of microstructure before and after wear.
