Swamp water typically has a high acid content and higher than normal concentrations of sulfates and chlorides, which are known to be more active in producing corrosion under normal conditions. This study aims to analyze and understand the corrosion rate and changes in the physical and mechanical properties of ASTM A36 steel that has undergone quenching heat treatment. Compared to steel ASTM A36 as received immersion in corrosive media using swamp water from The Village of Rambutan, South Sumatra Province, which has a pH of 3.00 with variations in immersion time of 48 hours, 96 hours, and 144 hours. The method used to determine the hardness value was the Brinell method, the corrosion rate was determined by the weight loss method, and SEM tests were carried out to determine the surface morphology of the specimens after immersion and XRD tests. The results showed that ASTM A36 steel specimens with quenching heat treatment had a higher hardness value than the as-received specimens; the greatest value was obtained in specimens with quenching treatment with immersion time. 48 hours, which is 497.97 BHN. The immersion test results showed that the highest corrosion rate occurred in the as-received specimen with a 144-hour immersion time of 17.6 mpy. Observation of the microstructure on the surface of the specimen found uniform corrosion and fitting corrosion; this was evidenced by the detection of iron oxide (Fe2O3), known as iron rust which is brownish-yellow in XRD testing.","PeriodicalId":16315,"journal":{"name":"Journal of Mechanical Engineering Science and Technology","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84359626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the important stages in the coal mining process is the weighing process used to measure the achievement of coal production and as a transactional tool. The weighing of coal is done using a bridging scale. The importance of the role in mining productivity must have strived for no failure in its main components, one of which is the weighbridge construction, where several occurrences of deformation occur in the main beam construction. Repair and strengthening efforts are carried out to overcome the deformation problems based on analysis and modeling using the software-based Finite Element Method. The material used is modeled using the Finite Element Method with loading FA = 41,618.18 N, FB = 51,087.56 N, and FC = 26,203.35 N towards the Z axis ST52-3 with Density 7,850 g/cm3, Yield Strength 345 Mpa, Tensile Strength 560 Mpa.

BC was disintegrated from the pellicle into bacterial nanocellulose (BNC) by using a high-pressure homogenizer (hph) machine, which has a three-dimensional woven nanofibrous network. The synthesis of composite films started when BNC, graphite nanoplatelets, and cetyltrimethylammonium bromide (CTAB) were homogenized using an ultrasonic homogenizer then baked on a glass mold at a temperature of 80 degrees Celcius for 14h. A scanning electron microscope (SEM) was used to analyze its morphology. X-Ray diffraction spectra were used to analyze the composite films structure. The functional groups of the composite films were analyzed using the FTIR spectrum. SEM micrograph shows that GNP was evenly distributed into BNC matrix after CTAB addition. GNPs are shown as flat and smooth flakes with sharp corners. Some peak corresponds O-H, C-H, C≡C, and CH3 stretching was identified by using FTIR spectroscopy at wavenumber 3379, 2893, 2135, and 1340 cm-1, respectively. XRD analysis shows that Crystalline Index (C.I) of BNC increases after 2.5 wt% addition of GNP. The presence of CTAB decreases C.I value of composite films. BNC/GNP composite films have the best mechanical properties with Young’s modulus about 77.01 ± 8.564.","PeriodicalId":16315,"journal":{"name":"Journal of Mechanical Engineering Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42883186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
