Abstract Material extrusion additive manufacturing provides an effective solution for fabrication of highly customized polyether ether ketone (PEEK) composite parts with any complex shape. Nevertheless, compared conventional methods, the mechanical strength 3D printed carbon fiber reinforced PEEK (CF/PEEK) composites is unsatisfactory due to weak interface bonding and high voids content induced by temperature difference. To overcome this challenge, a temperature‐control printer was used...
Abstract The orientation of fibers in polymer matrix plays a crucial role governing the performance composites including friction and wear. In present work, effect fiber on tribological behavior 3D printed short carbon reinforced PEEK (CF/PEEK) was studied by two series tribo‐tests, namely macro‐scale continuous sliding micro‐scale multiple scratching. Fiber orientations included parallel, tilted anti‐parallel relative to direction both macro micro It revealed that showed strong dependence...
The aim of this study was to compare the microstructure, mechanical, corrosion resistance and tribological properties ceramic coatings on 7075 aluminum alloy by micro-arc oxidation (MAO) technique in presence alkaline aluminate, silicate, phosphate solutions, respectively. SEM XRD were adopted element phase composition coatings. Their corrosion-resistance 3.5 wt% NaCl solution is investigated. In addition, performance evaluated a friction wear tester under dry sliding condition. It found...
Abstract Carbon fiber reinforced polyether ether ketone (CF/PEEK) composites are widely used as tribo‐materials in the aerospace and automotive industry. To amplify industrial utilization of extrusion‐based additive manufacturing fused deposition modeling fabricating CF/PEEK tribo‐composites, composites' microstructure–property relationship was studied with respect to carbon content varying between 5 wt% 30 wt%. This revealed that incorporation fibers helped enhance mechanical strength PEEK...
The purpose of this paper is to evaluate carbon spheres as a green lubricant additive in 5W30 engine oil reduce friction and wear. Carbon with diameter ∼400 nm are synthesized from glucose by using hydrothermal process. Lubrication studied ball-on-disk tribometer measuring the coefficient wear boundary lubrication regimes. worn surfaces were analyzed Raman spectroscopy. found be stably dispersed at 0.5 wt% concentration base oil. experiments revealed that effective reducing both when...
Abstract A study has been carried out to investigate the corrosive wear behavior of aluminum alloy 5052 (AA5052) under reciprocated sliding in 0.5 M sodium chloride solution by a ball‐on‐disc tribometer which is associated with potentiostat. It clearly observed that applied potential significant effects on tribological and electrochemical performance AA5052 testing solution. The friction coefficient decreases increasing from cathodic domain anodic one. total volume increases potential....
