“…As a consequence of the small displacement, it is much more difficult to remove the wear debris by fretting than by sliding. Under the action of the contact pressure, the friction heat and/or the ambient temperature, the remained wear debris can be compacted or even tribo-sintered to form tribolayers (Yang et al , 2021; Dreano et al , 2021; Pauly et al , 2021). Figure 1 presents a schematic illustration of the formation of tribolayers in fretting wear for the most frequently used sphere/cylinder-on-flat configuration.…”

Purpose Quantitative fretting wear prediction is of practical significance for industrial components. This study aims to establish a fretting wear model considering the formation of tribolayers and provide better fretting wear prediction. Design/methodology/approach Based on the characteristics for the formation of tribolayers, the ratio of fretting amplitude to nominal contact area length in the fretting direction is used to characterize their formation and contribution to the wear volume. The wear volume is then associated with the product of the friction energy and the ratio of fretting amplitude to nominal contact area length. Findings Better prediction in the wear volume can be achieved with the proposed fretting wear model by taking the formation of tribolayers into consideration. Originality/value The contribution of the formation of tribolayers to the wear volume is considered in the model and better prediction can be achieved.

“…Pauly et al [798] investigated the high temperature tribological performance of Incoloy 88HT and Inconel 617 alloys used as structural materials in high temperature gas cooled reactors. The tribological performance of these alloys becomes particularly important since impurities such as H 2 O and CH 4 in the coolant lead to corrosion reactions that will affect tribological performance of the components.…”

“…Many studies about alloys for different purposes were reported before [6][7][8][9][10][11][12][13][14]. Among the alloys, Ni-based alloys, Inconel-617 and Incoloy-800HT, were also studied by many researchers previously [1,4,[15][16][17][18][19][20]. The researches were generally focused on the oxidation behaviors in different environments, mechanical, metallurgical and tensile properties of the alloys 617 and 800HT.…”

In this paper, our purpose is to calculate photon-matter interaction parameters of Ni-based alloys, Inconel-617 and Incoloy-800HT, which are the main candidates for high-temperature applications such as spacecraft, gas turbines, nuclear reactors and rocket motors. The radiation attenuation parameters and buildup factors were obtained in a wide energy range by using Phy-X/PSD and EpiXS softwares to determine the radiation protection capabilities of the alloys. Fast neutron removal cross sections of the alloys were also calculated. It was observed that Inconel-617 has higher shielding ability than Incoloy-800HT. The shielding potentials of the alloys were compared with those of other shielding materials (ordinary concrete, hematite-serpenite, ilmenite-limonite, steelscrap, basalt-magnetite, steel-magnetite and ilmenite concretes) reported before, and it was concluded that Inconel-617 and Incoloy-800HT have more shielding ability than those.
