“…The material loss observed in the erosion tests can be attributed mostly to the abrasive form of erosion considering the angular shape of the silica particles. 60 Fig. 5 shows photographs (left) and SEM images (middle and right) of ungrafted (UG-BL) and linker-grafted (LG-BL) bilayers on steel substrates which were under sand erosion tests for 8 hours.…”

Ice formation and accumulation on surfaces can result in severe problems for solar photovoltaic installations, offshore oil platforms, wind turbines and aircrafts. In addition, blockage of pipelines by formation and accumulation of clathrate hydrates of natural gases has safety and economical concerns in oil and gas operations, particularly at high pressures and low temperatures such as those found in subsea or arctic environments. Practical adoption of icephobic/hydrate-phobic surfaces requires mechanical robustness and stability under harsh environments. Here, we develop durable and mechanically robust bilayer poly-divinylbenzene (pDVB)/poly-perfluorodecylacrylate (pPFDA) coatings using initiated chemical vapor deposition (iCVD) to reduce the adhesion strength of ice/hydrates to underlying substrates (silicon and steel). Utilizing a highly-cross-linked polymer (pDVB) underneath a very thin veneer of fluorine-rich polymer (pPFDA) we have designed inherently rough bilayer polymer films that can be deposited on rough steel substrates resulting in surfaces which exhibit a receding water contact angle (WCA) higher than 150° and WCA hysteresis as low as 4°. Optical profilometer measurements were performed on the films and root mean square (RMS) roughness values of Rq = 178.0 ± 17.5 nm and Rq = 312.7 ± 23.5 nm were obtained on silicon and steel substrates, respectively. When steel surfaces are coated with these smooth hard iCVD bilayer polymer films, the strength of ice adhesion is reduced from 1010 ± 95 kPa to 180 ± 85 kPa. The adhesion strength of the cyclopentane (CyC5) hydrate is also reduced from 220 ± 45 kPa on rough steel substrates to 34 ± 12 kPa on the polymer-coated steel substrates. The durability of these bilayer polymer coated icephobic and hydrate-phobic substrates is confirmed by sand erosion tests and examination of multiple ice/hydrate adhesion/de-adhesion cycles.

“…A jet rig system can be employed for both pure erosion under dry sand impingement using an air compressor [57][58][59] and erosion-corrosion under a slurry impingement using a fluid pump [13,[60][61][62][63][64][65][66][67][68]. This section only focuses on the slurry jet impingement systems which are used in the study of erosion-corrosion.…”

This paper firstly provides an overview of major efforts made over the past several decades on developing the test apparatus for the study of erosion-corrosion of ferrous-based steels. The merits and the application range of the set-ups, i.e., rotating disc/cylinder electrode system, slurry jet impingement rig, and test flow loop, are introduced. Secondly, the advantages and limitations of both non-electrochemical and electrochemical methods used for the measurement of erosion-corrosion are presented. Thereafter, the interaction between erosion and corrosion using a cyclic erosion-corrosion method was introduced. The synergy between erosion and corrosion for the steels under the passive state were analyzed on the basis of the breakdown and restoration of the passive film. In addition, the difference between the obtained erosion-enhanced corrosion and the corrosion-enhanced erosion using different experimental methods for steels under active corrosion was discussed. Finally, the interaction between the localized corrosion and erosion was studied through the dynamic change of the local current distribution revealed by the wire beam electrode.

Bu çalışmada, AISI 1020 çelik ve Ti-6Al-4V titanyum alaşım malzemelerinin katı partikül (parçacık) erozyon davranışları deneysel ve sayısal olarak incelenmiştir. Deneyler ve sayısal simülasyonlar, farklı partikül çarpma hızları (100, 127, 170, 210, 250 m/s) ve açıları (20, 30, 45, 60, 90°) için gerçekleştirilmiştir. Bununla birlikte, aynı malzemelerin bir helikopter pali aşınma kalkanındaki erozyon performansları, 0° hücum açısı ve 230 m/s çarpma hızı şartlarında MIL-STD-3033 standartına göre yapılmışken sayısal erozyon analizleri Eulerian-Lagrangian yaklaşımlı ayrık faz metodu ve ampirik erozyon eşitliği kullanan ticari ANSYS_Fluent 15.0 paket programı ile gerçekleştirilmiştir. Çalışmadan elde edilen sonuçlara göre, sayısal sonuçlar deneysel veriyle iyi derecede uyumlu ve AISI 1020 çeliğinin kalkan yüzeyindeki erozyon performansı Ti-6Al-4V alaşım malzemesinden daha iyi elde edilmiştir.Anahtar kelimeler: Katı partikül erozyonu, Hesaplamalı akışkanlar dinamiği, Helikopter pali, Aşınma kalkanı, AISI1020, Ti-6Al-4V
