“…Most of the cracks are multiple in nature and limited to local regions. Extending the logic presented by Soderberg et al [22], we conclude that cracks are generated in Al 2 O 3 phase. The propagation of the crack is limited by the presence of soft phase surrounding the hard phase.…”

“…The coating microstructure can be considered as a composite microstructure consisting of a hard phase (consisting of alumina) embedded in a relatively soft matrix made of metallic constituents. In such systems, Soderberg [22] suggested that the relative value of erodent particle size with respect to microstructural scale affects damage mechanism. When erodent particle size is larger compared to microstructural length scale, the damage due to individual impact overlaps the microstructural features and the damage within the feature is constrained by other features.…”

“…The crater formation is also possible if hard, angular particle impacts the soft matrix at an angle and in turn dislodges the particle from its site. Soderberg [22] believes that for this to happen, interfacial strength between soft phase and hard phase must be small.…”

 Abstract: In this present research work the solid particle erosion test carried on uncoated samples (Ti-31), and HVOF sprayed 10%Al 2 O 3 -CoCrAlTaY on Ti-31 are made. Erosion test are done with impact angles of 30º, 60º and 90º. Solid particle erosion studies were carried out using air jet erosion test rig as per ASTM G76-02 standard.All the three angles of uncoated alloys exhibit erosion damage under ductile mode and less amount of erosive loss compared HVOF coated samples. The HVOF sprayed coated Ti-31 at various impact angles is brittle mode. The mechanism of material removal during erosion of brittle materials is explained by using SEM micrographs.castings, shot peening of rotating components, cutting of hard and brittle materials by abrasive jets and rock drilling [3].

“…by Azimian and Bart [1]. However, less information on particle dynamics and erosion of materials in a centrifugal accelerator erosion tester is available [2,3]. Deng et al [4] performed detailed experiments to investigate the effects of solid particle dynamics on the erosion by blowing the particles with air into a centrifugal accelerator erosion tester.…”

“…During the last decades, polymers and their composites have been continuously displacing the conventional materials, due to their relatively simple processability, low manufacturing cost, and outstanding corrosion resistance . The enhanced physical, chemical, and engineering properties make these materials widely used in the industrial fields, to be specific, the fabrication of the helicopter rotors, wind turbine blades, water blades, aircrafts, sensors, electromagnetic interface (EMI) shielding, and pipelines .…”

A co‐coagulation method combined with hot pressing technique is successfully applied to fabricate thermoplastic polyurethane (TPU) nanocomposites with different contents of carbon nanotubes (CNTs). Obviously, the mechanical and thermal properties of the nanocomposites are improved with increasing the CNT content. In addition, the existence of hydrogen bonding between CNTs and polymer matrix is demonstrated. Furthermore, the influences of impact parameters on solid particle erosion behavior are investigated systematically. The surface roughness and line roughness are also investigated to illustrate the mechanism of solid particle erosion. As elastic nanocomposites, the maximum and minimum erosion rate (ER) occur at 30° and 90°. The ER is relatively small when the impact velocity is at 10 m s−1, then is increased rapidly between 20 and 30 m s−1. As the size of impact particles increases to 300 µm, a rapid increase of ER occurs between 10 and 20 m s−1. All these results indicate CNTs improve the erosion resistance of TPU matrix.
