“…The surface of the NS coating is smoother than the surface of the AR coatings. Beyond the effect of the higher microhardness of the NS coatings on its erosion resistance, its more regular and smoother surface [6] is also thought to have a beneficial influence on its resistance to erosion, at room and at higher temperatures, particularly when the micromachining mechanism [71][72][73][74] is operative.…”

This study reports the high temperature erosion-oxidation (E-O) behavior of conventional and nanostructured Cr 3 C 2 -25(Ni-20Cr) coatings prepared by high velocity oxygen fuel (HVOF) spraying. As-received and nanostructured Cr 3 C 2 -25(Ni-20Cr) powders with mean crystallite sizes of 145 nm and 50 nm respectively, were used to prepare 120 -200 μm thick coatings on AISI 310 samples. The E-O behavior of the coatings prepared with the as-received (AR) and nanostructured (NS) powders was determined as weight change in a custom designed rig at room temperature, 450, 700 and 800 ºC. The Vickers microhardness, Young's Modulus and fracture toughness of the AR and NS coatings were determined, and the NS coatings exhibited higher values compared with the AR coatings. The E-O resistance of the NS coating was higher than that of AR coating at all temperatures, and particularly at 800 ºC. The increase in E-O resistance of the NS coatings is due to its superior mechanical properties as well as to the presence of some heterogeneities in the AR coatings. The E-O mechanisms of both types of the coatings are discussed, with special attention to that at high temperatures. The results suggest that at 800 ºC the E-O process is controlled by erosion of the oxide.

“…Microcutting and micro-grooving were observed, as well as the presence of adiabatic shear bands. In the study of micro-mechanisms of abrasive wear, the influence of adhesion forces between the incidence particle and the material on the formation of wear products has been determined as significantly affecting [3]. The erosion wear of ductile materials depends on certain factors, including: incidence angle and particle velocity; shape, size and mechanical properties of the particle; temperature, size and shape of the eroded surface; the…”

The paper presents the test results of microstructure and resistance to abrasion and erosive wear of single and double-layer coatings with arc-coated powder wires on the iron matrix. It was shown that adhesion of coatings is in the range of 14.39 -24.72 MPa. The closed porosity of the coatings determined from SEM images is in the range of 0.69 -2.45% and was significantly lower than the porosity determined from the images obtained from the optical microscope, which was 5.49 -8.11%. The 95 MXC coating's hardness of the matrix was about 100HV 0.05 higher compared to the AMI 100 coating matrix. The intensity of the erosion of AMI 100 coatings was lower than the intensity of the erosion of 95 MXC coatings.

“…Dieser Abtragsmechanismus führt, wie zu erkennen ist, zur Erzeugung von Mikrospänen. Detaillierte Hochgeschwindigkeitsfilmaufnahmen von mit gezielt auf Stahloberflächen geschossenen spitzen Metallprojektilen ergaben jedoch, dass ein reines Mikroschneiden nicht die Regel ist [8]. Es wurde vielmehr festgestellt, dass in vielen Fällen ein "Furchungs"-Mechanismus dominiert.…”

“…This wear debris shape type covered about 60 % of all acquired debris. Plain micro-machining according to Finnie's (1959) suggestion played a negligible role only, but other processes, namely ploughing as suggested by Winter and Hutchings (1974), were more important. The statistically estimated mean debris size was about 14 lm.…”

Erosion of low-carbon steel by solid particle impingement: aspects of wear debris geometry Image analysis software was used to analyse the geometry of debris formed during the erosion of low-carbon steel by impinging solid particles. Depending on the two-dimensional aspect ratio (ratio between debris height and debris width), three different debris types could be distinguished. The most frequent type observed was a platelet-type debris as suggested by the Bellman- Levy (1981) model. This wear debris shape type covered about 60 % of all acquired debris. Plain micro-machining according to Finnie's (1959) suggestion played a negligible role only, but other processes, namely ploughing as suggested by Winter and Hutchings (1974), were more important. The statistically estimated mean debris size was about 14 lm. About 92 % of all wear debris had sizes smaller than the target material grain size. This result supports the figure that multi-step removal modes -the formation and detachment of lip or platelet from crater rims -were responsible for material removal.
