Optimization of Abrasive Wear Characteristics of Polyethylene/Acrylate Copolymer Nanocomposites
Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 Polymer nanocomposites are being used more widely in a variety of industries. As the compatibilizer, Elvaloy‐AC‐3427 (EAC) was used in addition to Cloisite 30B (C3B) as the reinforcement of filler in this research. For the production of Polyethylene/Cloisite 30B/Elvaloy AC‐3427 nanomaterials, a twin‐screw extruder is employed. Cloisite 30B was added to

Advances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021 While parts can be repaired via arc welding (AW), it is usually necessary to add some types of excitation method to improve the mechanical properties of the cladded layer. Here, the arc welding‐laser shock forging (AW‐LSF) was used to repair Q235 steel pipes (Fe‐Cr‐C alloy was used as the cladding material).
