The economic and effective operation of machinery and plant involved in fluids handling is increasingly dependent on the utilization of materials that combine high corrosion resistance and good wear resistance.The present study was undertaken in order to investigate the effect of solid particle erosion on the surface characteristics, the microstructure and the aqueous corrosion behavior of a Ti6Al4V sheet metal alloy. The scope of the present effort is to examine the possible way the solid particle erosion affect, by altering the Ti6Al4V surface characteristics, the subsequent electrochemical corrosion response. As for the solid particle erosion tests, three (3) different impact angles were selected, 30°, 60° and 90° degrees respectively. Angular alumina particles of 177 -250 μm size was used as the eroding media, injected, under 1 and 2 bars pressure, on the sample surface located at 10 mm distance from the injection nozzle. The mass loss was weighted and the wear rates were calculated. Surface roughness of the eroded surfaces was assessed and the microstructural modifications were evaluated using optical microscopy and SEM-EDX.Cyclic polarization measurements were conducted in an electrolyte simulating body fluids in order to ascertain the corrosion response of the surface treated samples. SEM-EDX analysis of the corroded surfaces was used in order to assess the corrosion mechanisms and the involved phenomena and to correlate them with the surface and the overall microstructural modifications.

“…Working environments of these components are very erosive and these components are strongly subjected to solid particle erosion. [1][2][3][4][5][6] Besides this, Ti6Al4V is typically used in either a mill annealed or solution treated and aged condition. Rapid quenching following solution treatment (water quench or equivalent) is important in order to maximise the formation of a' martensite phase, which maximizes the aging response.…”

In this paper, the erosive wear behaviour of Ti6Al4V alloy depending on various heat treatment conditions was evaluated. It is aimed to understand the relationship between the microstructure and the erosion rate of Ti6Al4V alloys. Furthermore, the hardness and the surface morphology variations depending on the annealing parameters and the effects of these parameters on the erosion behaviour of the annealed Ti6Al4V alloy were also considered. Moreover, eroded surfaces of samples were examined by using a scanning electron microscope in order to understand dominant material removal mechanisms depending on the annealing parameters. Results showed that the aging process has dramatically affected the erosion resistance of Ti6Al4V alloy. The microstructure and the hardness of the samples have significantly affected the erosion resistance of the alloy. Surprisingly, erosion resistance decreased when the hardness increased. Finally, SEM investigations of the eroded surfaces of the heat treated samples showed that microcutting and microploughing were the dominant erosion mechanisms occurred during the erosion process.

In this study, the effect of impact angle of the particles on solid particle erosive wear properties of basalt base glass-ceramics used for industrial applications was investigated. Commercial basalt glass-ceramic materials size of 20 × 20 × 3 cm was sectioned to the size of 5 × 5 × 1.2 cm. The experimental procedure was performed by using erosive wear test device with nozzle diameter of 0.78 cm. Na feldspar size of 300 µm was used as erosive media. The samples were fixed 2 cm distance from the nozzle, Na feldspar particles were sprayed by using 1.5, 3, 4 bar pressure for 20 s. The tests were repeated with 30• +45• +60• +75• +90• impact angles. The erosive wear rates were measured and the effect of particle impact angle on wear properties was determined.
