These four materials were chosen for the wear resistance characterization of SnPb-solder affected old/scraped copper (high Cu-Sn-Pb alloy) to explore its reusing potentials. Wear tests were conducted using a pin-on-disk tribometer with the applied load of 20 N for the sliding distance up to 2772 m at the sliding speed of 0.513 ms-1. The applied load was also changed to observe its effect. The investigation reveals that the presence of a small amount of Sn increased the hardness and improved the wear resistance of Cu, while a similar amount of Pb in Cu reduced the hardness but improved the wear resistance. The general perception of ‘the harder the wear resistant’ was found to match partially with the results of Cu, Cu-Sn alloy and Cu-Sn-Pb alloy. Coefficient of friction (COF) values revealed non-linear gradual increasing trends at the initial stage and after a certain sliding distance COF values of all four sample materials became almost steady. SnPb-solder affected Cu demonstrated its COF to be in between that of Cu-Pb alloy and Cu-Sn alloy with the maximum COF value of 0.533.","PeriodicalId":14603,"journal":{"name":"Iranian Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42285641","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}

In comparison to the base material AA6061, the composite produced had improved mechanical properties. The mechanical properties in the sintered composite samples such as tensile strength and hardness, are measured and compared to the wear-tested specimen. Optical micrographs reveal that composites were riddled with defects like blowholes, pinholes, and improper bonding between the particulates before sintering. However, the post-sintered optical micrograph showed that the defects were greatly suppressed. Micrographic images revealed the changes in surface characteristics before and after wear. Until a sliding distance of 260 m, the wear rate of the hybrid composites was kept lower than that of the base material. The coefficient of all the composite materials produced in this study was less than that of the base material. The results reveal that the hardness of hybrid composites having 4 and 6 wt. % of TiB2 particulates increased by 5.98 and 1.35% respectively. Because of the frictional heating during the wear test, the tensile properties lowered by up to 49.6%. It is concluded that the hybrid composites having 4 and 6 wt. % of TiB2 particulates exhibited less wear rate for extended sliding distance, good hardness, moderate tensile strength, and decent elongation percentage compared to the base material counterparts.","PeriodicalId":14603,"journal":{"name":"Iranian Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46680471","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}

The modification interface of the electron transport layer and the perovskite absorber layer plays an important role in the efficient charge extraction process at the interface. In this study, planar perovskite solar cells with configuration (FTO/SnO2/mixed-cation perovskite/CuInS2/Au) were prepared to investigate the effect of UV-Ozone (UVO) treated SnO2 as ETL on the performance of devices. ETL treatment was performed at different times (0 to 60 min). It is shown that surface wetting was improved by UVO treating the SnO2 films prior to deposition of the perovskite layer. The latter improves the contact between the ETL and the perovskite layer, allowing more efficient electron transport at the interface. Contact angle, SEM, photoluminescence spectra, and the current density-voltage tests were conducted to characterize the photovoltaic of the cells. The best PSC performance with a power conversion efficiency of 10.96% was achieved using UVO-treated SnO2 ETL for 30 min, whereas the power conversion efficiency of the perovskite solar cells with SnO2 ETL without UVO treatment was only 4.34%.","PeriodicalId":14603,"journal":{"name":"Iranian Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45844344","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}
