“…A selection of the most relevant studies to this work is listed in Table 1 and these are discussed below. KIM et al [15] reported increasing erosion rates with increasing coating hardness. ZHANG and DONG [16], DJUROVIC et al [17] and LI et al [18] determined particle impact velocity and diameter to be the most important variables influencing the erosion rate.…”

A dynamic indentation experiment is presented for assessment of the adhesive behavior of a range of coatings in erosive defouling of commercial aircraft engines using CO 2 dry-ice. A series of experiments is presented in which particles made from a reference material (polyoxymethylene-POM) and from CO 2 dry-ice are made to impact compressor airfoils under a range of impact angle and velocity conditions. The airfoils investigated are coated with an indicator material (PTFE), which is typically used to visualise the defouling effect in large scale compressor defouling experiments. In addition, fouled compressor airfoils taken from service and coated with a fouling typically found in low-pressure compressor stages are investigated. The energy required for the reference particles (POM) to create a defouling effect for the different coatings is determined by an experimental evaluation of their coefficient of restitution. This energy requirement is assumed to be fouling specific. Empirical defouling functions are presented. They correlate the defouling effect for both particle materials under various impact conditions. The empirical correlations are developed into a simulation procedure to predict particle impact erosion and energy dissipation of coated surfaces in numerical indentation simulations.

“…Kapalı eşitlikler olarak FLUENT programında değişik türbülans modelleri yer almaktadır. Literatürdeki çalışmalara bakıldığında katı partikül erozyonunun HAD ile analizleri yapılırken genellikle en iyi yakınsama ve hassas sonuçlar vermesi nedeniyle − SST türbülans modeli tercih edilmektedir [11], [21]. Bu çalışmada, Eşitlik 3 ve 4'te kapalı eşitlikleri verilen − SST türbülans modeli HAD analizleri için kullanılmıştır [14].…”

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

Erosion wear caused by solid particles is a big challenge in the oil and gas industry, which seriously threatens the long-term safe operation of the equipment. A novel experimental apparatus was set up to meet the requirements for accelerating erosion wear research process for abrasion resistant materials, with a capability of producing high speed particles to impact target specimen. The erosion wear experiments of NiWC35 coating and sintered WC were conducted under different amounts of abrasive, temperatures, and impact angles respectively. Their macroscopic and microscopic erosion damage morphology and mechanism were discussed and analyzed. The results show that the amount of abrasive, temperature and impact angle have a more significant effect on the erosion wear of NiWC35 coating than sintered WC. The erosion rate of NiWC35 coating increases approximately linearly with the increase of the amount of abrasive; the impact angle of the NiWC35 coating is smaller, the range of erosion pit is wider; while the erosion wear morphology and erosion rate of sintered WC basically unchanged under different variables, countless fine irregular particles in the microscopic surface is the key to excellent abrasion resistance of sintered WC.
