“…In general, the value of H s increases and w ss decreases with the hardness, except for the M3 sample, indicating that higher hardness does not imply a better scratch resistance for those martensitic materials. Similar results have been previously reported by Gui-jian et al [30] who studied the effect of DC plasma nitriding temperature on the microstructure and the dry-sliding wear properties of 316L stainless steel. They observed that the wear rate increased when the hardness was too low, but among the hardest samples, those which had lower hardness presented lower wear rate.…”

“…In general, hardness has a direct influence on dry wear resistance according to the Archard's law, although microstructure and ductility play also an important role in the wear phenomenon [30]. In order to precisely explain the wear resistance of martensitic stainless steels, a correlation of the microstructure with the hardness and the scratch resistance as well as with the wear mechanisms is studied.…”

Tribological Behavior of New Martensitic Stainless Steels Using Scratch and Dry Wear Test

et al. 2014

This paper focuses on the tribological characterization of new martensitic stainless steels by two different tribological methods (scratch and dry wear tests) and their comparison to the austenitic standard stainless steel AISI 316L. The scratch test allows obtaining critical loads, scratch friction coefficients, scratch hardness and specific scratch wear rate, and the dry wear test to quantify wear volumes. The damage has been studied by ex situ scanning electron microscopy. Wear resistance was related to the hardness and the microstructure of the studied materials, where martensitic stainless steels exhibit higher scratch wear resistance than the austenitic one, but higher hardness of the martensitic alloys did not give better scratch resistance when comparing with themselves. It has been proved it is possible to evaluate the scratch wear resistance of bulk stainless steels using scratch test. The austenitic material presented lower wear volume than the martensitic ones after the dry wear test due to phase transformation and the hardening during sliding.

“…4a. The formation of cracks maybe related to the presence of fractured ceramic particles on the wear tract as mentioned by other researches [43]. Wear tracks of Ti(C,N) single layer coatings showed a very irregular surface with much discontinuity beside wear track.…”

“…As, it was mentioned by Jianxin et al [42], the minimum speed for the chemical wear mechanism in these coatings was 1.5 m/s to produce high temperature (about 500°C) to form TiO 2 . In mechanical wear mechanism, the fractured small ceramic particles from coatings on the surface of specimens can act like the secondary moving indenters [43].…”

Mechanical properties of multilayer and multicomponent coatings were investigated in this paper. Titanium nitride/titanium carbide (TiN/TiC-n) multilayer and Ti(C,N) multicomponent coatings were prepared on the surface of AISI H13 hot work tool steel by the pulsed-DC plasma assisted chemical vapor deposition (PACVD). The microhardness, the toughness, the wear loss, and the friction coefficient were examined by Vickers hardness test and the pin-on-disk wear test. The optical microscopy was also used to examine worn surfaces and to characterize wear mechanisms. The results obtaiond show that multilayer coatings of TiN/TiC-10 have the lowest friction coefficient (as 0.2) and wear loss, the highest toughness (as 17. 7 MPa m 1 / 2 × ) and microhardness (as 3150 VHN) among those values for multicomponent Ti(C,N) coatings and other multilayer coatings.
