“…Finite element modelling techniques can be employed to better understand the nature and potential effects of sand and dust impingement on a blade leading edge. Numerous studies have looked at modelling solid particulate impact and erosion on solid target bodies across a variety of research fields and using both commercial and purpose made models [88] [89] [90] [91] [92]. As with rain and hail modelling, these approaches could be utilised as both a design and evaluation tool for the blade leading edge.…”

The increasing developments in wind turbine technology, coupled with an unpredictable operating environment, presents significant challenges regarding erosion issues on the leading edge of the blade tips. This review examines the potential degradation posed by the different environmental variables, with specific emphasis on both rain droplet and hailstone impact on the blade leading edge. Drawing on both the insights from experimental results and recent field data from the literature, the mechanisms of leading edge erosion are discussed. Meteorological tools that may enable rain and hailstone erosion prediction are addressed as well as potential experimental and numerical approaches that may provide insight into the nature of impact and erosion on the blade surface.

“…This, together with the irregularity of particle shape and size typically found in erodent powders, and the complexity of the deformation and damage behavior of materials under impact loadings, makes it very challenging to identify the micro-mechanisms of erosion that lead to macro-scale material loss. These complexities have led researchers to take simplified approaches in order to understand erosion mechanisms in ductile materials [2].…”

Aluminum alloys are one of the most common materials used in aircraft structural part production. Moreover, high cruising speeds of aircrafts resulted with high velocity impacts of micro hard particles such as dust, fly ash, impact ice and rain droplets. These hard particles involved in atmospheric air concentration cause repeated impacts on surface Extruded AA6082-T6 aluminum alloy sheets were subjected to solid particle erosion tests. Solid particle erosion tests were performed according to ASTM G 76 standard. Abrasive particles with various particle sizes blasted to surfaces of AA6082-T6 aluminum alloy test coupons. Solid particle erosion tests accomplished at normal incidence (impact angle:90°) with blast pressure of 3 Bar. Average roughness (Ra), average distance between the highest peak and lowest valley in each sampling length (Rz) and 3D surface topography maps and erosive wear rates of AA6082-T6 aluminum alloy test coupons were obtained before and after solid particle erosion tests. Correlations between erosion crater volume and mass loss were discussed.

“…Among Al-Co alloys prepared by vacuum arc melting (VAM), casting and free sintering, the former have exhibited superior microstructure in terms of uniformity and fineness that has led to superior corrosion and sliding wear performance [15]. On the above grounds and considering that the erosion response of Al-alloys, MMCs (Metal Matrix Composites), ICs and CMAs has become an important aspect of their application potential [18][19][20][21][22][23], the present work examines the solid particle erosion response of Al-Co in-situ composites prepared by VAM and compares it with that of commercially pure Al (CP-Al) also prepared by VAM(Al-VAM).…”

The present effort studies the comparative solid particle erosion behaviour of Al-Co alloys of various compositions in the AlAl 9 Co 2 side of the Al-Co phase diagram. The alloys have been prepared by vacuum arc melting. The main concept behind the selection of the Al-Al 9 Co 2 region of the Al-Co phase diagram was the attainment of a two-phase structure (Al + Al 9 Co 2 ) that could combine the beneficial attributes of Al 9 Co 2 , as a Complex Metallic Alloy in-situ reinforcement, with the ductility/toughness of Al, as a matrix to the brittle intermetallic.Hypereutectic Al-Co alloys of various Co contents (7, 10, 15 and 20 wt.% Co), as well as monolithic commercially pure Al, were prepared by vacuum arc melting. The alloys were subjected to solid particle erosion testing at two impact angles (60° and 90°). The test results were interpreted based on weight change measurements and scanning electronic microscopy. It was revealed that the governing mechanisms change as the impact angle and the reinforcement volume fraction change. It was shown that factors affecting the brittle/ductile character of the material, such as Al 9 Co 2 volume fraction, Al 9 Co 2 coarseness, Co dissolved in Al, play a primary role on the erosion response of the alloys. The Al-Co alloys showed higher wear rates than Al. The wear rate increased with Co and, consequently, Al 9 Co 2 increasing. The surface characteristics and degradation mechanisms are being discussed.
