“…The second zone B can be characterized as the stabilization of COF values. In the case of 16Mo3 steel, we can see that there is a gradual slight increase in COF, which is caused by the gradual increase of the contact area depending on the changes in the asperity of the surface [ 45 , 46 ]. The COF in the second zone B of the undeformed Inconel 625 material remained stable because there was a uniform exfoliation of the surface particles in the tribological process and thus a dynamic equilibrium was achieved [ 47 , 48 ].…”

The presented work deals with the investigation of mechanical tribological properties on Inconel 625 superalloy, which is welded on a 16Mo3 steel pipe. The wall thickness of the basic steel pipe was 7 mm, while the average thickness of the welded layer was 3.5 mm. The coating was made by the cold metal transfer (CMT) method. A supercritical bending of 180° was performed on the material welded in this way while cold. The mechanical properties evaluated were hardness, wear resistance, coefficient of friction (COF) and change in surface roughness for both materials. The UMT Tribolab laboratory equipment was used to measure COF and wear resistance by the Ball-on-flat method, which used a G40 steel pressure ball. The entire process took place at an elevated temperature of 500 °C. The measured results show that the materials after bending are reinforced by plastic deformation, which leads to an increase in hardness and also resistance to wear. Superalloy Inconel 625 shows approximately seven times higher rate of wear compared to steel 16Mo3 due to the creation of local oxidation areas that support the formation of abrasive wear and do not create a solid lubricant, as in the case of steel 16Mo3. Strain hardening leads to a reduction of possible wear on Inconel 625 superalloy as well as on 16Mo3 steel. In the case of the friction process, the places of supercritical bending of the structure showed the greatest resistance to wear compared to the non-deformed structure.

“…The velocity change of the CrAlN coating is less than that of the CrN coating, except at RT with sand environment, indicating that the kinetic energy absorbed by the former coating is less than that of the latter coating, as shown in Figure 5a. The absorbed kinetic energy is mainly used for wear during the impact test [33][34][35]. The velocity change of the CrN and CrAlN coatings is larger under the sand condition than under the no-sand condition.…”

The impact wear resistance of the hard coating is very important in the high-temperature environment of the nuclear power plant. CrN and CrAlN coatings were prepared using multi-arc ion plating. The impact abrasive wear resistance of the coatings was investigated at varied temperatures through a controlled kinetic energy impact wear rig, and their impact mechanism was elucidated. No extensive spalling was found on the surface of the CrN and CrAlN coatings after 104 impacts under the no-sand condition. The excellent antioxidant properties of the CrN and CrAlN coatings can protect the substrate from oxidation under the no-sand condition at 500 °C. The impact mechanism of the two coatings was plastic deformation under the no-sand condition, and it was mainly material removal under the sand condition. The depth and width of wear scar were larger under the sand condition than under the no-sand condition. The impact wear region was divided into a mixed impact zone and a sand impact zone. Compared with the CrN coating, the CrAlN coating had lower impact force and shallower impact wear scar, proving that it has better anti-impact wear properties.

“…Depending on the different relative movement forms of wear contact pairs, the wear forms of Inconel 690 alloy that suffered during its service period can be roughly divided into impact wear, sliding wear, impact-sliding wear, and torsional wear [4,5]. The impact wear behavior can be defined as a dynamic process that the material surface is subjected to the impact of foreign objects, causing the loss and spalling of its surface materials [6].…”

As an important nuclear power material, Inconel 690 alloy always need to suffer various harsh impact wear behaviors during its service period. Therefore, how to further enhance its surface wear resistance and objectively reveal its fretting wear mechanism under various conditions have vital scientific values for improving its service performance. This study first applies specific ultrasonic surface rolling process (USRP) to treat the Inconel 690 alloy surface with two and four times separately. And then a controllable impact kinetic energy wear test rig is used to comparative investigate the impact wear behaviors of as-received and USRP treated samples at 25 ℃ and 300 ℃ temperature. Results indicate that USRP can effectively improve the near surface Nano-hardness, residual compressive stress and other mechanical properties of Inconel 690 alloy, thereby increasing its impact wear resistance. The impact wear mechanism at 25 ℃ is plastic deformation causes fatigue spalling, and some adhesion wear are found at the 300 ℃ wear condition.
