The solid-particle erosion of metals and alloys at elevated temperatures is characterized by different mechanisms of material removal, depending on the temperature of exposure, impact velocity, impact angle, and flux rate of the eroding particles. The objective of this article is to delineate the prevalent erosion mechanisms in nickel and a nickel-20 chromium alloy over a large range of temperatures, impact velocities, impact angles, and particle feed rates. For this purpose, a specialized elevatedtemperature erosion rig has been utilized. Nickel and a Ni-20Cr alloy have been chosen as the test materials, in view of their substantially different oxidation behaviors. Results from the present study indicate that while the erosion rate generally increases with increasing temperature, an increased particle feed rate causes a reduction in the erosion rate, especially at higher temperatures beyond 650 K. On the basis of a detailed examination of the morphology of the eroded surfaces and the subsurface features beneath the eroded surfaces, four different material removal mechanisms have been identified in the nickel, while only three material removal mechanisms were operative in the Ni-20Cr alloy. Utilizing the aforementioned information, erosion-oxidation (E-O) interaction mechanism maps (herein, termed E-O maps) delineating the regions of dominance of the various erosion mechanisms in an impact velocity-test temperature space have been constructed for Ni and a Ni-20Cr alloy. Finally, the differences in erosion behavior between the Ni and Ni-20Cr alloy have been identified and rationalized.

“…Even at elevated temperature, if one considers the erosion behaviour of metallic material at high impact velocities and feed rates, the oxidation plays an insignificant role and the erosion behaviour is essentially metal erosion behaviour. The experimental data of Shida and Fujikawa [42] pertaining to 1.25 Cr-1Mo-V, 2.25Cr-Mo, 12Cr-1Mo-V and plain carbon steel (up to 923 K), that of Singh and Sundararajan [36,43] pertaining to 304, 316, 410 stainless steel (up to 773 K) and that of Levy et al [44,45] pertaining to 2.25Cr-1.0Mo steel, 5Cr-0.5Mo steel, 1018 steel, 304 SS, 310 SS, 410 SS and 17-4 PHSS can be considered elevated temperature erosion of metals with minimum or negligible oxidation. Under such conditions the dependence of the strength of the material on temperature is a reasonable indicator of the temperature dependence of erosion resistance of the materials.…”

Solid particle erosion of metals and alloys at elevated temperature is governed by the nature of the interaction between erosion and oxidation, which, in turn, is determined by the thickness, pliability, morphology, adhesion characteristics and toughness of the oxide scale. The main objective of this paper is to critically review the present state of understanding of the elevated temperature erosion behaviour of metals and alloys. First of all, the erosion testing at elevated temperature is reviewed. This is followed by discussion of the essential features of elevated temperature erosion with special emphasis on microscopic observation, giving details of the erosion–oxidation (E–O) interaction mechanisms. The E–O interaction has been elaborated in the subsequent section. The E–O interaction includes E–O maps, analysis of transition criteria from one erosion mechanism to another mechanism and quantification of enhanced oxidation kinetics during erosion. Finally, the relevant areas for future studies are indicated.

“…Nevertheless, a number of questions regarding correlations between erosion properties and physical parameters of materials remain unanswered. Information available about the conjoint effect of erosion and oxidation at high temperatures is still limited [4][5][6] . The results of some of the erosion-oxidation (E-O) studies demonstrate that there is synergy between erosion and oxidation.…”

The high temperature oxidation and erosion-oxidation (E-O) behavior of steels AISI 1020, 304, 310, and 410 were determined. These steels were selected to evaluate the effect of chromium content on its E-O resistance. The oxidation behavior was determined in a thermogravimetric analyzer. A test rig in which a specimen assembly was rotated through a fluidized bed of erodent particles was used to determine the E-O behavior. Alumina powder (200 µm) was used as the erodent. The E-O tests were carried out in the temperature range 25-600 °C, with average particle impact velocities of 3.5 and 15 ms -1 and impact angle of 90°. The oxidation resistance of the steels increased with chromium content. The E-O behavior of the steels was determined as wastage. The E-O wastage of the steels exposed to particle impact at low velocity was low but increased with temperature above 300 °C. The E-O wastage of the different steels exposed to particle impact at high velocity was quite similar. The wastage increased with increase in temperature above 500 °C. The increases in E-O wastage of the steels observed at temperatures above 300, 400 or 500 °C, depending on the steel, were due mainly to a transition in the dominant wastage process, from 'erosion' to 'erosion-oxidation'.
