“…To solve the contradiction mentioned above, some factors that may influence the tribocorrosion behaviour of hull steel can be considered, including load [4,7,8], velocity [9][10][11], temperature [2,12], microstructure [13][14][15], atmosphere [3], and hardness [16,17]. In general, hardness plays a critical role in the frictional and wear resistance of steel materials, even though other factors such as load and microstructure are also of vital importance in marine environment.…”

“…Tribocorrosion is a main failure cause of hull steel components in offshore applications due to the synergistic effect of mechanical wear and corrosiveness in seawater [2]. It enables a greater loss of material than that when wear or corrosion takes place individually [3]. In reality, total material loss during tribocorrosion consists of the mechanical wear without corrosion, the corrosion without wear, and the sum of the interactions between the wear and the corrosion [4].…”

The tribocorrosion behaviour of two different hull steels (namely, EH36 and EH47) was investigated using a ball-on-disk tribometer under varying normal loads from 10 to 100 N in a 3.5 wt% NaCl saline solution. Sliding in pure water was also performed for a comparison purpose. The results indicate that the corrosion products mainly consist of lath lepidocrocite (γ-FeOOH) with residual NaCl crystals when sliding against both steels EH36 and EH47 in the saline solution. Tribocorrosion on EH36 (pearlitic steel) shows lower coefficient of friction (COF) values than those obtained in water, while tribocorrosion on EH47 (bainitic steel) leads to higher COF values instead. The former is due to the formation of considerable hydroxide particulates and films with small sizes. In contrast, the latter is ascribed to the ploughing of hydroxides with smaller amounts and bigger sizes. In particular, the synergistic effects of corrosion and wear in tribocorrosion result in much higher total materials degradation, compared to that obtained through pure mechanical wear in water.

Übertragbarkeit des Gleitkorrosionsprüfstandes auf die ÖlfeldanwendungenZusammenfassung: In der Ölfeldindustrie bewirken die Gleitkorrosionsmechanismen eine Verringerung der Lebensdauer der Steigrohre bei Bohrlöchern. Das Ziel dieser Arbeit ist es, das Tribokorrosionsverhalten von niederlegierten Kohlenstoffstählen (C-Stähle) in sauerstofffreier Umgebung mit dem Gleitkorrosionsprüfstand zu beschreiben. Der nachstehende Teststand hat eine sehr hohe Wichtigkeit für die Ölindustrie und wurde am Ös-terreichischen Kompetenzzentrum für Tribologie (AC²T research GmbH) entwickelt. Der Vorteil dieses Teststandes ist es, einen Überdruck der CO 2 Atmosphäre realisieren zu können und zusätzlich unterschiedliche Parameter wie pH-Werte, Cl Ionenkonzentration, usw. zu messen. Einflüsse auf die Korrosion wie zum Beispiel Flüssigkeits-bewegung, Dampfkorrosion, usw. können in einer Korrosionsteststandzelle kontrolliert eingestellt und bestimmt werden. In der Gleitkorrosionsteststandzelle werden zusätzlich zu den korrosiven Bedingungen ein Gleitkontakt zwischen Muffe und Steigrohr realisiert. Die Ergebnisse zeigen einen hohen Einfluss der Gefügestruktur auf das Verhalten und Lebensdauer der Steigrohre unter Gleitkorrosion. Die dominanten Schädigungsmechanismen im Ölfeld konnten mit dem entwickelten Gleitkorrosionsprüf-stand gut nachgebildet werden und stellen dabei nicht nur einen wirtschaftlichen Vorteil für Unternehmenspartner dar, sondern bilden auch eine wichtige Wissensbasis für weitere Aktivitäten auf dem Gebiet der Gleitkorrosion.Abstract: Sliding-corrosion phenomena play a crucial role in reducing the lifetime of tubings in the oil production industry. The aim of the present work is to develop and apply a close-to-reality test rig to describe the tribological performance of low-alloyed Carbon-steel (C-steel) under sliding-corrosion conditions in O 2 -free environment. The proposed test rig is highly relevant for the oil production industry and has been designed at the Austrian Competence Center for Tribology (AC²T). The benefit of this equipment is that it allows the setting of the CO 2 atmosphere at a certain partial pressure while simultaneously varying the pH-value, Cl − ion concentration, and temperature of the electrolyte solution. Pure corrosion phenomena are investigated within a designed coupon box where conditions of steam, electrolyte injection, static, and dynamic flow are controlled. In addition to the corrosive environment, a tribological reciprocating sliding contact is implemented between tubing segments and coupling samples. Within this study, a commercially available lowalloyed C-steel was selected as base material for the tubing, which was tribologically stressed under reciprocating sliding contact against spray metal coated couplings. The results show a high influence of the steel microstructure on the performance of low-alloyed C-steel tubings under sliding-corrosion. Additionally, the dominant damage mechanisms that are observed in real field applications could be successfully reproduced by experimental...

“…Esses autores observaram que o comportamento do aço foi afetado pelas modificações na superfície do material, relacionadas à camada encruada formada na superfície desgastada e oxidação desta, devido ao processo simultâneo de desgaste e corrosão. Efetuando ensaios de deslizamento na presença de CO2 e 3,0% de NaCl, o efeito da microestrutura do aço, martensítica ou ferrítico-perlítica, foi avaliado por Trausmuth et al [13]. Eles verificaram que a camada de óxido formada na martensita era mais densa, o que favoreceu o menor desgaste comparado à outra microestrutura.…”

Resumo: A interação entre desgaste e corrosão, ou seja, a tribocorrosão, ocorre em diversas aplicações industriais e biomédicas e pode levar a uma degradação acentuada do material. O objetivo do presente trabalho foi comparar a resistência ao desgaste em meio aquoso de juntas similares de um aço martensítico (Hardox 500), e de juntas dissimilares entre o aço Hardox e um aço SAE 1010. As juntas foram obtidas empregando-se o processo de soldagem arco submerso, com energia de soldagem de 7,7 kJ/cm. Ensaios de microdesgaste por deslizamento linear recíproco foram realizados na presença de água artificial (0,05 M NaCl), em amostras de dois conjuntos soldados, um de materiais similares e outro de materiais dissimilares. As regiões ensaiadas foram os metais de solda (MS) e as zonas afetadas pelo calor (ZAC), estas últimas nas sub-regiões que apresentavam o menor valor de dureza, em cada conjunto. Para comparação, também foram ensaiados os metais-base (MB) do aço SAE 1010 e do aço Hardox. Como as chapas de aço Hardox possuíam um revestimento de silicato de zinco, condição na qual o aço era fornecido, para este aço os ensaios de corrosão-desgaste foram efetuados em amostras com o revestimento, e também sem ele. Dentre todas as condições estudadas, a maior resistência em tribocorrosão foi verificada para o aço Hardox com o revestimento. Das amostras ensaiadas sem revestimento, a degradação ocasionada pela tribocorrosão foi menor no MB do aço Hardox. Nos demais casos, foi observada a corrosão intensificada pelo desgaste, principalmente para o MB do SAE 1010, onde houve a dissolução acentuada do material adjacente à borda da trilha, fora da região de desgaste.
