“…Figure 6a shows the worn surface morphologies of specimen CNE0. Furrows, plastic deformation, and clear adhesive took place on the worn surface of specimen CNE0, which was attributed to severe plastic deformation and adhesive wear [12,21]. This was consistent with the result of pure copper possessing the highest wear rate.…”

This paper presents a facile and effective method for preparing Ni/NbSe2 composites in order to improve the wettability of NbSe2 and copper matrix, which is helpful in enhancing the friction-reducing and anti-wear properties of copper-based composites. The powder metallurgy (P/M) technique was used to fabricate copper-based composites with different weight fractions of Ni/NbSe2, and tribological properties of composites were evaluated by using a ball-on-disk friction-and-wear tester. Results indicated that tribological properties of copper-based composites were improved by the addition of Ni/NbSe2. In particular, copper-based composites containing 15 wt.% Ni/NbSe2 showed the lowest friction coefficient (0.16) and wear rate (4.1 × 10−5 mm3·N−1·m−1) among all composites.

“…The oxidation reactions occur on the surface of brass during the friction test. The accumulation of ZnO, which is well known as a solid lubricant [34], leads to the reduction of friction for sliding. ZnO, which is as a buffer to prevent the direct contact between the friction pairs, inhibits friction and maintains the friction coefficient and wear rate with relatively low and stable in the third stage of Fig.…”

“…Although Alloy A had a lower hardness than tool steel, it had a very low wear rate. As can be seen in Table 4, it reached a very high hardness level after the wear test since cold work and oxide formation occurred [25][26][27][28]. It is known that when oxides are present at high temperatures they play the role of a solid lubricant by forming glazed surfaces.…”

“…This effect is called friction-induced work hardening rate (FIWH) [25]. The formation of cold worked and a continuous oxide layer during high temperatures was identified by Jens Hardell et al and Q. Y. Zhang et al [27,28]. The hardened layer acts as a lubricant if it occurs on a hard substrate.…”

This paper is an investigation into the use of Fe-based alloys as part of wear resistant hardfacing materials in AISI 1.2714 tool steel. Four different weld hardfacing alloys were deposited on 1.2714 steel substrates using tungsten inert gas welding (TIG) process. Wear tests were carried out using a pin-on-disc wear tester at room temperature. Microhardness and micrographs of the weld overlays were obtained. High-temperature properties were estimated by numerical analysis. The phases of the hardfacings were obtained by XRD and also estimated by numerical analysis. The results from the laboratory tests were then compared with the results obtained from field studies. The results showed that some Fe-based alloys improved dies lifetime; others created poor surfaces. A Fe-based hardfacing alloy D which included high C with Cr, W, Mo had the best wear behavior among the weld overlays.K e y w o r d s : hardfacing, Fe-based alloy, JmatPro, die failure mode, hot forging performance tests
