“…In another study, Cai et al [ 20 ] conducted high-temperature erosion tests on three typical boronized coatings and observed that the single-phase Fe 2 B coatings exhibited a superior erosion resistance to that of the dual-phase boronized coatings. The numerical simulation results [ 21 ] further confirmed the experimental findings. Prescott [ 22 ] used 150 μm quartz sand particles to impact different boronized coatings and substrate test pieces at a speed of 36 m/s by employing the sandblasting test setup.…”

In this study, the high temperature erosion mechanisms and damage characteristics of a boronized coating have been systematically studied by employing an improved high-temperature accelerated erosion test bench and impact contact theory analyses. Within the scope of the experimental parameters, the erosion rate of the boronized coating under the same erosion conditions was observed to be only one half to one-twelfth of the erosion rate of the substrate. Furthermore, the boronized coating was noted to be less sensitive to the speed of the erosion particles than the plastic substrate, thus, indicating superior and more stable erosion resistance than the base material. The boronized coating exhibited typical brittle fracture characteristics under impact by the high-speed particles. When the particle impact normal stress exceeded the critical stress for crack propagation owing to the coating defects, the surface and subsurface layers of the coating initially formed horizontal and vertical micro-cracks, followed by their gradual expansion and intersection. After destabilization, the brittle coating material was peeled layer-by-layer from the surface of the test piece. At the same incident speed, as the particle size was increased from 65 μm to 226 μm and 336 μm, the size (width) of the erosion cracks on the coating surface increased from 1 μm to 30 μm and 100 μm respectively. Correspondingly, the erosion damage thickness of the coating was enhanced from 15 μm to 50 μm and 100 μm. In the case of the quartz sand particle size exceeding 300 μm, the dual-phase boronized coating did not provide effective protection to the substrate. Furthermore, based on the elastoplastic fracture theory, a prediction model for the erosion weight loss of the boronized coatings within the effective thickness range has been proposed in this study.

“…Indeed, a number of papers have been published in which Finite Element Method (FEM) or alternative methods have been employed to simulate the particle-wall impingement processes at the micro-scale and accurately predict the removal of material for specific combinations of abrasive particles and target body, but they typically ignored the influence of the fluid on the particle transport at the macro-scale level [5][6][7].…”

“…In initial studies, transition metal nitrides exhibited great application potential in solid particle erosion resistance [2,[6][7][8]. In recent studies, single-layer nitride coatings with high hardness were commonly used to resist solid particle erosion [9][10][11][12]. With further research, single-layer coatings were observed to be easily detachable with an increase in thickness, especially at the edge of samples.…”

Ceramic coating is an effective method for improving the erosion resistance of a material, particularly for titanium alloys. In this study, a TiN/ZrN (ceramic/ceramic) nanoscale multilayer coating is designed and prepared on the Ti6Al4V titanium alloy surface by the physical vapor deposition (PVD) process. The cross-sectional microstructure and phase composition are measured using SEM and XRD, respectively. The hardness, elastic modulus, and adhesion of the coating are measured by the nano-indentation and scratch method. The erosion test is conducted at a 45° angle with 100 m/s velocity using self-developed erosion equipment. The erosion resistance mechanisms of both the substrate and the coating are revealed more intuitively through a single sand particle impact test. The results show that the erosion resistance rate of the coating is 15.5 times higher than that of the titanium alloy substrate. The damage mechanisms of material removal of the coating include crack deflection, crack branching, and succeeding interaction between them when suffering an impacting load. These cracks are started from the droplets and the stress concentrations on the coating surface during the preparation of coating. They are the primary reasons for the decrease in the erosion resistance of the coating. This research is important for the optimization of the erosion-resistant coating structure.
