“…Stage 2 is of a two-step aging process, in which the printed material was maintained at 720°C for 8 h, then it was cooled down to 620°C in 2 h, and then it was soaked at 620°C for 8 h. After which the samples were trimmed for metallurgical analysis such as x-ray diffraction analysis and scanning electron microscopic analysis. Wear test as per ASTM: G99 standard was conducted in DUCOM pin on disc tribometer with load, build direction and sliding velocity (Baskaran et al , 2014; Jia and Gu, 2014; Thirugnanasambantham and Natarajan, 2016). With selected parameters, a standard L 9 orthogonal array opted as shown in Table I, and the experiments were carried out for 2,000 m sliding distance with cylindrical samples of 8 mm diameter and 30 mm length.…”

“…Inconel 718 was fabricated by laser deposition technique with the raw materials in the form of powders and wires, and observed a similar strength in both conditions (Arrizubieta et al , 2017). Dry sliding wear behaviour of IN718 and Hastelloy was studied at 500°C temperature under varying loads and observed that the load influences the wear mechanisms (Thirugnanasambantham and Natarajan, 2016). Material Co 28 Cr 6 Mo was produced using the selective laser melting technique to investigate its wear properties, and the results showed higher wear compared with the forged material (Mróz et al , 2017).…”

Purpose Aerospace and defence industries use the materials having better properties at elevated temperatures, and Inconel 718 is one of that. The complexity in realizing complex and intricate shapes necessitate the product realization through additive manufacturing. This paper aims to investigate the wear behaviour of additive manufactured material. Design/methodology/approach The wear behaviour of additively manufactured Inconel 718 samples through direct metal laser sintering process at three different build orientations was experimentally investigated using a standard pin-on-disc wear tester. Findings Among the varied wear parameters, the load was identified as the most influencing parameter on the wear rate. In addition, the post-failure analysis of the worn surface of the pins under the scanning electron microscopy revealed the presence of various wear mechanisms. Originality/value Almost, the industries are now focussed on their production through additive manufacturing owing to its advantages. The present work displays the wear behaviour of the additive manufactured Inconel 718 and its associated wear mechanisms.

“…According to the hardness results given in Figure 7, while the hardness of the alloys increased (the amount of Y 2 O 3 additive phase increased), the friction coefficient (µ) increased. Thirugnanasambatham et al [43] reported that the particles formed between the friction surfaces locked each other and prevented the sliding motion. Also, Panagopoulos et al [44] reported that while the applied load on Ni-based superalloys increased, the debris between the rubbing surfaces increased, resulting in a decrease in the contact area and a decrease in the friction coefficient.…”

This paper investigated the wear performances of Y2O3 doped MA6000 (Ni-Cr-Al) alloy produced by mechanical alloying (MA). Produced, all powders were pre-formed by cold pressing and sintered in a vacuum environment. Sintered MA6000-X% Y2O3 superalloys were characterized by scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD) analysis, density, and hardness measurements. Wear tests of Y2O3 added MA6000 alloys were carried out in a block-on-ring type wear device. In the wear tests, the sliding speed of 1 ms-1 at room temperature (RT) was performed under five different sliding distances (200-1000m) and three different loads (5 N, 10 N, and 15 N). As a result of the studies, it was determined that the MA?ed MA6000 superalloy powders were homogeneous and flake shape. With the increase amount of Y2O3, hardness of these superalloys increased from 267 to 431 Hv, but the density slightly decreased. Different intermetallic/carbur phases such as Ni3Al, MoC are observed in all compositions. Wear tests show that weight loss and wear rate decreased, and friction coefficient (?) increased with the increasing amount of Y2O3 additive. Besides, it was determined that as the applied load increased in the wear test, the weight loss increased, but the wear rate and friction coefficient (?) decreased.

“…The wear mechanism of cutting tool while machining Hastelloy C-22HS is also investigated by researchers [7]. Recently, study pertaining to the sliding wear properties and mechanism of Inconel 718 and Hastelloy X at a temperature of 5000C is reported [8] which reveals that shear band and debris formation on the surface are the main reasons for the wear in case of Hastelloy X.…”

Hastelloy C276 is investigated for dry sliding wear against an EN 31 stainless steel (hardness 60 HRC) at 298 K. The tribological properties such as frictional force, coefficient of friction and the wear rate on the material surface at different sliding distance are examined under different loading conditions. In the dry wear test at 40 N load, the wear rate increased by 300% as compared to 10, 20, 30 N loading conditions. The experimental results indicated reduction in coefficient of friction values and thus an increase in the frictional force with the increase in normal load. SEM images of worn out surfaces confirm that the delamination and adhesion causes the material removal from the surface in dry sliding. Further, the analysis of the hardness characteristics of worn out surfaces shows surface hardening during sliding wear process under 40 N load
