“…In our case the absence of defects and a high hardness of CrN condensates evidences on the high wear resistance of the coating. According to [27] such properties can provide the fretting-corrosion protection of fuel tubes in the reactor under normal operating conditions. Besides, the Cr-N coating should decrease the tube surface damage, when pulling through the spacer grids that leads to the fuel-element failure.…”

Sung et al [9] compared the wear volumes and wear mechanisms of TiN coated and uncoated zircaloy-4 tubes with a cylinder-to-cylinder contact test rig. Larbi et al [10] investigated the fretting damage of multilayer PVD TiAlCN/TiAlCN/TiAl coating and uncoated AISI 4140 steel.…”

The feasibility of alleviating torsional fretting wear of the blade bearing by preparing PVD TiCN coating was studied. The results show that the friction torque was highly influenced by the wear debris acting as the solid lubricant. The TiCN coating reduced the wear volume by 97.6% and 62.3% in oil and artificial seawater, respectively, which was mainly due to an increase in surface hardness. In oil, the produced sulfates and phosphates prevent seizures between the friction pair and the worn surface was characterized by polishing wear. In artificial seawater, the wear mechanism was a combination of mechanical wear and corrosion wear. This study reveals that the TiCN coating is suitable for alleviation of fretting wear in the blade bearing.

“…Some common applications of zircaloy for Indian Pressurised Heavy Water Reactors (PHWRs) are fuel cladding, coolant tube, and bearing pads for fuel element. Tribological properties of zircaloy material have been evaluated by many researchers; however, considering its application for fuel cladding tube, most of the research work is done for fretting wear analysis [2][3][4][5]. Sliding wear studies are rarely performed and only a few cases are available in literature [6,7].…”

Current work was simulated for sliding wear interaction of materials of fuel bundle bearing pad (zircaloy-4) and magazine rotor tube (AISI 304 stainless steel) of Indian Pressurised Heavy Water Reactors (PHWRs). A plan of experiments, based on the techniques of Taguchi, was performed. The objective was to establish a correlation between load and sliding speed with the volume loss and coefficient of friction (COF). These correlations were obtained by multiple linear regressions. The treatment of the experimental results is based on the analysis average and the analysis of variance (ANOVA). Worn surface analyses carried out using SEM and wear mechanisms were identified. ANOVA analysis indicated that load factor has a great influence on the coefficient of friction (∼73%). COF suddenly increases to high value after a particular contact pressure due to absence of lubricating film and increase in metal to metal contact. Volume loss of AISI 304 stainless steel and zircaloy-4 is highly affected due to load (∼90%) and speed (∼65%), respectively. Worn surfaces exhibited deformation, adherence, and compaction of material at all PV conditions. Contact pressures above 475 MPa indicated formation of ratcheting mechanisms and formation of fatigue striation marks. Due to low yield strength of AISI 304 SS, volume loss was on higher side than that of Zr-4.
