Abstract Thermo-anodization technology has been considered as an effective means to improve the thermal, physical and chemical properties for metal alloy. In this work, we achieve a porous black layer on surface of aluminium alloy through environmentally friendly anodic oxidation process, with high thermal emittance (0.96) solar absorptivity (0.921). addition, thermo-anodized coating shows uniq...
The following investigation shows the experimental evaluation of a transient heat load centered on corrosion inhibitor coating employed in epoxy polyamide primary. temperature at which film initiated thermal deterioration increased with heating rates. This is Deft Inc.'s high- quality solid A single inch diameter lamp two types aluminum substrates was focused xenon flashlight: AA2024- T4 and AA...
This study experimentally investigates the influence of adding SiC on microstructure and mechanical properties aluminium alloys welded joints. The particles have been directly added into a zone friction stir welding (FSW) to make (AA6061–AA2024) composites material. Results show that effect refines grain size in by preventing its growth during FSW process. has significant thermomechanical resul...
In this study, the effects of different welding parameters applied during laser AA2024 aluminum alloy materials on tensile strength were investigated and their optimizations made using Taguchi ANOVA methods to obtain most suitable parameters. The variable such as power, pulse duration, beam power density energy used in study. As a result, it was concluded that lowest obtained when 1800 W 5 ms 6...
فرآیند جوشکاری اصطکاکی اغتشاشی بر روی ورق های آلیاژ آلومینیوم 2024-t351 در سرعت های دورانی 400، 630 و 800 دور بر دقیقه و سرعت های پیشروی 8، 16 و 25 میلی متر بر دقیقه انجام شده است. پس از آن با استفاده از روش تست استاندارد astm-e647 نرخ رشد ترک خستگی در نمونه های ct مورد بررسی قرار گرفته است. پس از مدل سازی فرآیند جوشکاری اصطکاکی اغتشاشی، رشد ترک خستگی بر مبنای روش xfem، در نمونه ها شبیه سازی شد...
