Verschleißverhalten von additiv gefertigten Kunststoff-Kunststoff-Gleitpaarungen

Abstract

For industrial applications, additive manufacturing becomes more and more important due to its unrivaled design and materials freedom. In this light, additively manufactured polymer-polymer sliding combinations gain increasing interest for manifold tribological applications. This potential can be fully exploited, e.g., by using tribologically tailored compounds. For additive manufacturing not only the sliding combinations but also the understanding of the influence of printing parameters are important. Thus, this work is a first investigation of commercially available tribological compounds regarding their wear behavior by means of the ball-prism wear test. On that basis, influences of printing orientation and material combination on the wear behavior are investigated. In addition, interactions of these parameters will be discussed. Finally, the challenges of test specimen production as well as wear measurements are considered.

“…Therefore, optimized tribological material pairs are needed for polymer-polymer sliding contact to ensure longevity. 27 While two materials may be sufficient to adjust the clearance, using more than two could be beneficial. A combination of a tribologically optimized, structural-mechanical…”

“…To further improve the lifespan of such non‐assembly mechanisms, material combinations with pure PLA may not be suitable in terms of tribological properties. Therefore, optimized tribological material pairs are needed for polymer–polymer sliding contact to ensure longevity 27 . While two materials may be sufficient to adjust the clearance, using more than two could be beneficial.…”
