“…In the plasma spray welding technique, suitable alloy powders are selected according to the actual conditions and requirements of surface properties [14][15][16]. A spray welding layer of cobalt-based alloy has an excellent high temperature impact wear resistance and outstanding high temperature oxidative stability [17,18].…”

Plasma spray welding, as one of the material surface strengthening techniques, has the advantages of low alloy material consumption, high mechanical properties and good coating compactness. Here, the Co alloy, WC and Fe-based amorphous alloy composite coating is prepared by the plasma spray welding method, and the coating characteristics are investigated. The results indicate that the coatings have a full metallurgical bond in the coating/substrate interface, and the powder composition influences the microstructures and properties of the coating. The hardness of coatings increases with the mass fraction of the Fe-based amorphous alloy. The spray welding layer has a much higher wear resistance compared with the carbon steel, and the Fe-20 exhibits a superior wear resistance when compared to others. The results indicate that the amorphous alloy powders are an effective additive to prepare the coating by plasma spray welding for improving the wear resistance of the coating.

“…Researchers have studied the characteristics of fractured surfaces using observational tools, from macro- to nanoscale [ 13 , 14 , 15 , 16 , 17 ]. Unfortunately, even though advanced methods such as optical coherence tomography [ 18 ], scanning acoustic microscopy [ 19 ] or energy response approach based on strain energy density histories during variable loading [ 20 , 21 ] are described in the literature, usually simple-fracture qualitative analysis conducted with scanning electron microscopy is employed for the evaluation of surface fractures resulting from impact [ 22 , 23 ], tensile strength [ 24 , 25 ], fatigue [ 5 , 19 ], ultra-high fatigue [ 26 ], adhesion testing [ 27 ] or even wear damage description [ 28 , 29 ]. However, few studies have investigated the use of profile and surface roughness as a tool for fatigue fracture characterisation.…”

Post-mortem characterisation is a pivotal tool to trace back to the origin of structural failures in modern engineering analyses. This work compared both the crack propagation and rupture roughness profiles based on areal parameters for total fracture area. Notched and smooth samples made of weather-resistant structural steel (10HNAP), popular S355J2 structural steel and aluminium alloy AW-2017A under bending, torsion and combined bending–torsion were investigated. After the fatigue tests, fatigue fractures were measured with an optical profilometer, and the relevant surface parameters were critically compared. The results showed a great impact of the loading scenario on both the local profiles and total fracture areas. Both approaches (local and total fracture zones) for specimens with different geometries were investigated. For all specimens, measured texture parameters decreased in the following order: total area, rupture area and propagation area.

“…According to the literature, bulk cobalt-and nickel-based metal alloys have superior resistance to both cavitation erosion and sliding [18][19][20]. Moreover, Co-, Ni-or even Fe-based overlay deposits are considered highly resistant to both abrasion and erosion [21][22][23]. It is known that thermally sprayed coatings increase the wear resistance of machine and equipment components and make it possible to prevent or reduce various damage processes.…”

AbstractThe investigation into wear resistance is an up-to-date problem from the point of view of both scientific and engineering practice. In this study, HVOF coatings such as MCrAlY (CoNiCrAlY and NiCoCrAlY) and NiCrMo were deposited on AISI 310 (X15CrNi25-20) stainless steel substrates. The microstructural properties and surface morphology of the as-sprayed coatings were examined. Cavitation erosion tests were conducted using the vibratory method in accordance with the ASTM G32 standard. Sliding wear was examined with the use of a ball-on-disc tribometer, and friction coefficients were measured. The sliding and cavitation wear mechanisms were identified with the SEM-EDS method. In comparison to the NiCrMo coating, the MCrAlY coatings have lower wear resistance. The cavitation erosion resistance of the as-sprayed M(Co,Ni)CrAlY coatings is almost two times lower than that of the as-sprayed NiCrMoFeCo deposit. Moreover, the sliding wear resistance increases with increasing the nickel content as follows: CoNiCrAlY < NiCoCrAlY < NiCrMoFeCo. The mean friction coefficient of CoNiCrAlY coating equals of 0.873, which almost 50% exceed those reported for coating NiCrMoFeCo of 0.573. The as-sprayed NiCrMoFeCo coating presents superior sliding wear and cavitation erosion resistance to the as-sprayed MCrAlY (CoNiCrAlY and NiCoCrAlY) coatings.
