Ball-on-flat linear reciprocating tests: Critical assessment of wear volume determination methods and suggested improvements for ASTM D7755 standard Ayerdi, Jon Aginagalde, Andrea Llavori, Inigo Zabala, Alaitz Bonse, Jörn Spaltmann, Dirk Wear Sliding Surface Analysis ASTM D7755-11 This work presents a critical assessment of wear volume determination methods for ball-on-flat linear reciprocating sliding tribological tests. It revealed that the ASTM D7755-11 standard leads to the highest relative errors (up to 106%) and deviations (up to 27%) depending on the regularity of the wear track shape. The present study suggests improvements for the ASTM D7755-11 wear computation, which can reduce errors from 106% to 17% when analysing irregularly shaped wear tracks. In addition, a five-year period review of two relevant tribology journals revealed that the most used methods for wear determination, namely three-dimensional (3D) profilometry (46%) and nonstandard profile-based methods (36%), are overall reported with incomplete procedural information for wear computation. Furthermore, as many as 8% of the papers specify no data regarding the computation method and only 3% explicitly cited and followed the existing standards (ASTM D7755-11 or G133-05). The present study highlights the importance of the correct selection, implementation, and reporting of wear volume computation method and quantifies the potential errors. 2021-02-15T10:27:00Z 2021-02-15T10:27:00Z 2021 http://purl.org/coar/resource_type/c_6501 0043-1648 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=162588 https://hdl.handle.net/20.500.11984/5217 eng © 2021 Elsevier B.V.
