“…Additional information on its operational conditions is available in [21,31]. To replicate the most severe and frequent damaging conditions in which such hardfacing operates under operational conditions [27], an impact angle of 15 • was adopted. Test parameters, i.e., flow rate, injected powder flow rate, and test duration, were determined through computational fluid dynamics simulation, maintaining a working condition with constant kinetic energy of erodent particles.…”

“…In this scenario, this study is intended to investigate the combined effects of substrate microstructure and erodent particle characteristics on the erosion resistance of the adopted HCCIs. The proposed analysis originates from a specific application of HCCIs, namely the critical surfaces of large industrial fans [27], where conditions of erosive wear from solid particles are a limiting factor for the components' lifespan. The evaluation of the cast iron's erosive wear resistance was carried out in accordance with ASTM G76 standards, using a dedicated test bench and employing commercially controlled granulometry powder as erodent particles.…”

This research addresses the erosive resistance of a hypereutectic high-chromium cast iron subjected to solid particle erosion. The study stems from a specific application of high-chromium cast iron, i.e., the critical surfaces of large industrial fans operating in a cement clinker grinding plant where such damage is a limiting factor for the components’ lifespan. A dedicated experimental investigation on the impact of substrate microstructure and erodent particle size on erosion resistance was set. The experimental campaign, conducted on a dedicated test bench per the ASTM G76 standard, comprised the analysis of the as-received, tempered, and destabilized conditions for the cast iron. From a preliminary image analysis of the microstructural features, two diameters of the erodent powder for the erosion tests were defined. The observed erosion rate decreased with the increase in the mean particle diameter of the erodent, indicating more severe erosive conditions for smaller particles. From the analysis of the worn surfaces, it was possible to highlight the involved mechanisms concerning the considered test combinations. For the as-received condition, the erosion rate with the larger mean particle diameter of the erodent decreased three times compared to the smaller one. For the heat-treated conditions, the erosion rate was halved with the larger mean particle diameter of the erodent. The proposed analysis, intended to acquire more insight into the limiting factor for the components’ lifespan for erosive wear damage, proved that erosion resistance is not dependent on the material’s hardness. The contribution of the mean particle diameter of the erodent is predominant compared to the substrate conditions.

The present study is directed to the problem of hardfacing and restoration of worn industrial equipment. Wear tests were carried out using especially built rig which reproduces working conditions of machinery applied in cement plants. The results of tribological tests on 20 Fe-and Ni-base hardfacings are presented. The effect of hardfacing hardness and chemical composition was evaluated. It was found in SEM examinations that matrix was removed from the zone adjacent to carbides which made them liable to cracking and digging out. The mechanism of matrix removal depended on its hardness and include microcutting and low cycle fatigue. Ni-based hardfacings outperformed Fe-based coatings. The abrasion resistance of the best Ni-base coating, the Stelcar 6 was 38.7 times higher than that of S235JR steel. Eutectics in Ni-base coatings disturb motion of abrasive grains and force them to rotate instead of sliding over hardfacing surface. Ni-based coatings can be considered in hardfacing or reclamation of numerous industrial components applied in cement plants.

“…Ongoing efforts are mainly devoted to the reliability of engineering systems [6][7][8] and improvements in materials' properties [9][10][11]. For instance, in the case of machinery operating with contaminated fluids, erosion and deposition phenomena [12][13][14] induce long-term alterations in the material's structure, resulting in performance deterioration, heightened noise and vibration, and ultimately, premature and unforeseen component failure [15][16][17].…”

This study analyzed the influence of tempering treatment temperature on the microstructural and mechanical behavior of two different powder metallurgy steels containing 0 wt. % Ni and 4 wt. % Ni. The evolution of the microstructure and the macro- and microhardness of the microstructural constituents resulting from tempering treatments conducted on the sinter-hardened materials at temperatures ranging from 160 °C to 300 °C were investigated. The role of the tempering conditions in the impact behavior was assessed using Charpy tests on V-notched and unnotched samples, tempered at 180 °C, 220 °C and 280 °C. The observed macrohardness reduction with increasing tempering temperature was related to martensite transformations. At high tempering temperatures, the remarkable loss in impact energy values was attributed to microfracture modes. The contribution of Ni-rich austenite areas in enhancing impact strength was detected.
