Evolution of wear damage in Inconel 600 alloy due to fretting against type 304 stainless steel

Combined effect of gamma-radiation and pH on corrosion of Ni–Cr–Fe alloy inconel 600

“…The relative intensities of the Ni-2p, Cr-2p and Fe-2p peaks in the XPS survey spectra obtained at different pHs and radiation environments are shown in Fig. 5 [4][5][6][7][8]32,33,[48][49][50][51][52][53][54][55]. At pH 10.6 the enrichment ratio for Cr is lower and that for Fe is higher in the presence of radiation compared to those in the absence of radiation.…”

“…Deposition of radioactive materials on coolant system components outside of the biological shielding of the reactor core creates a potential source of radiation exposure for plant workers. Nickel-chromiumiron alloys such as Inconel 600 are known for their high resistance to corrosion and are used for thin-walled heat exchanger tubing in the steam generators in nuclear power plants [4][5][6][7][8]. The tubing is exposed to gamma-radiation (emitted from the fission products and neutron activation products).…”

“…It may consist of a graded series of different oxides with one of more metal ions incorporated into the oxide lattice structure. Although oxide film formation on Inconel 600 has been investigated extensively [4][5][6][7][8][32][33][34][35][36][37][38][39][40][41][42][43], most of these studies were performed over a limited range of environmental conditions. For example, oxide film formation has been studied in neutral pH water at 325 • C [32], in highly acidic and basic solutions at 350 • C and 320 • C [33], respectively and in pure water at 288 • C [5].…”

Fretting Wear Analysis of Different Tube Materials Used in Heat Exchanger Tube Bundle

“…From the results he obtained that wear scar depth, wear volume and plastic regime at the edge of the scar first increased slowly with the increase in number of cycles and then showing a significant increase, consequently resulting in transformation of wear mechanism from adhesive wear to mixture of delamination wear and oxidation. With the further increase in number of cycle, stick zone disappeared resulting in the formation of tribologically transformed structure (TTS) which was later on destroyed by the micro rack formation and propagation [15]. In order to reduce the damage caused by wear in tube's material, wear mechanisms should be analyzed at different test parameters such as applied normal load, temperature, counterpart material and sliding amplitude.…”

Effect of PCGTAW on the Inconel 690 alloy with respect to microsegregation attainment in comparison with the base metal processed with autogenous welding

“…The researchers realized many examinations of the SG-tube fretting wear and life predictions with the help of the data from macroscopic analyses of the wear coefficient, wear volume and so on. [23][24][25][26][27] In addition, a microscopic analysis of fretting wear involves cracks, structures, oxidation processes and the characteristics of the oxide debris between contact surfaces. [28][29][30][31] This super alloy has been studied and analyzed for various mechanical and metallurgical properties.…”
