“…It has been reported in the literature [34,35] that the erosion rate is proportional to the velocity according to a power law relationship where "n" is the exponent of the power law. At room temperature, the n for SiC-based ceramics has been found to be~2, which corresponds to brittle fracture mechanisms [33][34][35]. It was found in [27] that n was two at room temperature for these SA-MI composites.…”

“…Such conditions can result in hard particle erosion or molten deposition onto CMC and/or CMC/EBC materials. For hard particle erosion, considerable work has been performed by Choi and coworkers on many different substrate materials at room temperature [32,33]. However, no work had been performed at an elevated temperature.…”

The Versatility of HVOF Burner Rig Testing for Ceramic Matrix Composite Evaluation

Effective testing of ceramic matrix composites (CMCs) and CMC/coating systems for high temperature, high stress, high velocity and/or severe oxidation/corrosion environments is a critical need in materials/coatings evaluation for extreme environments of hot section parts in jet engine and hypersonic applications. Most current technology can evaluate two or three of the extreme conditions for a given application; however, incorporating as many of the extreme thermo-mechanical-environmental factors is highly advantageous to understand combinatorial effects. A high velocity oxygen fuel (HVOF) burner rig offers an excellent platform to evaluate many of these extreme conditions. In this work, the following three different thermo-mechanical-environmental test conditions using an HVOF rig on SiC-based CMCs are highlighted: (1) fatigue at temperature for >Mach 1 velocity and high temperature compared to typical stagnant air test environment, (2) high temperature hard particle erosion at temperature for ≤Mach 1 conditions and (3) ~Mach 5 near-hypersonic velocity conditions at very high temperature exposure.

“…Material removal due to the repeated impact of solid particles, termed solid particle erosion (SPE), is a common phenomenon that is observed in both the cold and hot sections of gas turbine engines operating in particulateladen environments. [1][2][3][4] SPE is of particular concern for military aircraft which often operate in harsh, erosive environments, [1][2] but the phenomenon is also encountered by commercial aircraft. [3][4] SPE in gas turbine engines can occur while taxiing or during takeoff due to the ingestion of particulates from the runway, or at altitude as a result of airborne particles.…”

Solid particle erosion in ceramic matrix composites and environmental barrier coatings: A perspective

2023

Ceramic matrix composites (CMCs) and environmental barrier coatings (EBCs) are key technologies that can enable improvements in the thermal and propulsive efficiency of gas turbine engines. However, CMCs and EBCs are susceptible to various life limiting damage modes associated with the engine operating environment such as oxidation, recession, thermomechanical stress/strain, corrosion, foreign object damage (FOD), and solid particle erosion (SPE). Despite its importance, there is a limited understanding of the SPE behavior of CMCs and EBCs in the literature. This paper reviews the status of SPE research in CMCs and EBCs and provides a perspective towards future research.This article is protected by copyright. All rights reserved

“…Zhang et al propose that the impacting angle has a substantial influence on the mechanism's erosion [33]. Presby et al [34] and Panakarajupally et al [35] research outcome has identified the role of particle speed in erosion rate. Sharma et al examined at how concentration and particle interface influenced erosion rate and concluded that both factors had a large effect [36].…”

One of the most serious concerns for the industry is material degradation, which leads to premature failure. Solid particle erosion (SPE) is a significant material degradation phenomenon. To be more specific, the erosion problem is made worse by the fluid inclusion of gravel and other contaminants. Despite being well studied and predicted, the process of solid particle erosion is still not properly known. Therefore, additional experimental research is still required to properly understand the erosion process and offer novel erosion resistance strategies. Employing coatings is the most effective technique to reduce/prevent solid particle erosion. The most commonly used methods to improve erosion resistance are proper material selection and the application of coatings. The erosion behaviour of atmospheric plasma-coated Nichrome (NiCr) on coated and uncoated duplex stainless steel (DSS2205) substrates were investigated. The erosion test is performed using an air-jet erosion tester with alumina as the erodent at velocities of 150, 175 and 200 m/s, impact angles of 30°,45° and 90°, and discharge rates of 2.5, 3.75 and 5 gm/min. This study discovered that the most influential factors of erosion are impact angle. When the impact angle is 90°, the velocity is 150 m/s, and the discharge rate is 5 gm/min, the erosion was minimal. Analysis of the surface microstructure reveals many erosion mechanisms linked to various incidence angles. The erosion mechanism changes from micro-ploughing to plastic deformation for low to high impactangles. Furthermore, metallographic examinations are used in conjunction with the experimental results. As per the experimental findings, coating bare substrates with NiCr can substantially increase erosion resistance. Moreover, NiCr coatings on bare substrates showed a 47% reduction in erosion wear, primarily as a result of their better toughness, higher density, improved micro-hardness, and lower porosity.
