“…Presence of oxygen in the EDS analysis might be due to the oxidation of molten particles during flight and after the deposition on the substrate. Similar results have been reported by Vencl et al., 24 Zhang et al., 25 and Martin et al. 26 The authors reported a lamellar structure of NiCrSiFeBC /WC–Co plasma spray coatings with the presence of some defects such as oxide layers, micropores, and inclusions.…”

“…Existing literature studies endorse these results. Zhang et al 25 reported g-Ni, FeNi 3 WC, and W 2 C phases in the XRD spectrum of plasma-sprayed NiCrSiFeBC/ WC-Ni composite coating. Serres et al 19 manufactured NiCrSiFeBC-WC coatings using hybrid plasma/laser process and found out from XRD patterns that Ni, (Cr Fe) 7 C 3 , CrB, and Ni 3 B phases were formed in the coating, and the presence of WC and W 2 C phases were also detected by the XRD analysis.…”

Knowledge and optimization of tribological behavior of hot forming dies play an important role in attaining high process productivity. But research in this field has been limited. Keeping this in view, the current investigation aims to explore the potential of atmospheric plasma sprayed (APS) 65% (NiCrSiFeBC)–35% (WC–Co) coating in optimizing friction coefficients and minimizing the wear of AISI H11 and AISI H13 hot forming steels at elevated temperatures. Detailed characterization of the as-sprayed specimens was carried out using scanning electron microscopy/energy-dispersive spectroscopy and X-ray diffraction techniques. Wear and friction tests were done utilizing a high-temperature pin-on-disc tribometer under two different loads and temperatures ranging from room temperature to 800 ℃. The results have shown that the developed coating exhibited lower porosity, higher microhardness, and performed much better than the uncoated specimens. The wear mechanisms of the coated specimens were mainly abrasive at room temperatures and 400 ℃. Fatigue, tribo-oxidation, and three-body abrasion were observed as the dominant mechanisms at 800 ℃.
