“…It was found that the wear resistance of hardfacing depends on the microstructure obtained after hardfacing and the parameters of the depositing process. Öztürk [31] studied the wear behaviour and microstructure of Fe-C-Si-Cr-B-Ni hardfacing alloys, with the addition of ferronickel (FeNi) and ferroboron (FeB). It was found that, at room temperature, wear occurs through a combination of local delamination of surface layer and abrasive grooving.…”

In this study, hardfacing deposits using materials of different surface hardness are investigated using an innovative strategy for tribological testing. The abrasive wear behaviour of AISI 316L stainless steel is compared to the Cr–Ni–Mn alloy (OK Autrod 16.95) and the Cr-Mo alloy (Fluxofil 58), deposited on a substrate of S355JR steel. A modified three-body abrasion test and a modified scratch test were used to evaluate the tribological behaviour and wear mechanisms of these materials. The modified double-pass scratch test on the abraded surfaces is analysed using the geometrical parameters of grooves to aid in predicting the lifetime of machinery parts in abrasive working conditions. This leads to a shortening of the resistance to abrasion wear time of the evaluation of the abrasion wear resistance of materials. The validation of the results obtained in the double-pass scratch tests was carried out using three-body abrasion tests, according to the ASTM G65 standard. Wear mechanism investigations were carried out by scanning electron microscopy and three-dimensional surface topography and was analysed using an optical microscope. The results obtained from experimental research show that double-pass scratch tests demonstrated that it is possible to shorten the time needed to predict the abrasive behaviour of materials using this method.

“…Fe-C-B-Cr alloys has excellent wear resistance, good corrosion resistance, and oxidation resistance [8]. The more widespread by Fe-Cr-B-C and Fe-Cr-B-C-Ti system alloys, which have the best mechanical properties and wear resistance [10][11][12][13]. Available information suggests that the abrasive wear resistance of materials depends on factors like microstructure (their size and content), and mechanical properties of materials [14].…”

Hardfacing process commonly employed because of its low cost and high efficiency. The microstructure of an two sample of deposited metal by X-ray diffraction, scanning electron microscope (SEM). In this research, the mechanical and tribological properties of two deposited metal of Fe–C–Cr–B–Ti alloying systems, high chromium 140Cr13Si1MnBTi alloy, and low chromium and high copper 110Cr4Cu7TiVBAl alloy hradfecing by flux-cored arc welding process (FCAW) was studied. It provided a low content of chromium (4 wt.%) and a high content of copper (7 wt.% Cu). Results of the studies had showed that the introduction of exothermic addition (CuO‒Al) to the core filler of the flux‒cored wire electrode, change melting characteristic and provides the highest resistance of the deposited metal to abrasion wear due to additional alloying by copper and reduction in grain size.

The tribological properties of aluminum based Al-25Zn-1Mg alloy was experimentally investigated in an MSc thesis, and the results are presented in this study. To this purpose, Al-25Zn-1Mg was commercially produced by casting. The prepared samples were divided into seven groups: no-process, solution treatment, and artificial aging for 1, 3, 6, 12 and 24 hours. Aged and untreated samples were subjected to tribological experiments under conditions of dry friction under 5 N and 10 N loads at speed of 200 rpm, 400 rpm and 800 rpm for a distance of 500 m. As a result of the tests, it was found that hardness increases in all samples depending on the aging process. It was also found that when the test speed was kept constant, the coefficient of friction increased with increasing load.
