The experimental part involved the realization of tensile tests of different materials, namely samples with [0/90] 2S uniaxial layer configuration and [0/90] 2S twill fabric samples. Both types of tests were monitored using one wideband acoustic emission sensor, while the tensile tests of twill fabric samples were additionally supplemented with resonant acoustic emission sensor to perform a comparative analysis between datasets from resonant/wideband acoustic emission sensor. The comparative study itself was preceded by the failure mechanisms characterization process, which has been performed on the tensile test dataset of [0/90] 2S layer configuration with the contribution of clustering technique. The subsequent analysis of the twill fabric resonant/wideband acoustic emission sensor datasets included the improved b-value technique, which relates the magnitude of fracture with the slope of the amplitude distribution. The presented results, especially in terms of the improved b-value technique applied to individual clusters, show enhanced ability to assess in more detail the actual structural integrity depending on the applied load.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":"31 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135584162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phosphating of the zinc surfaces raises its roughness and surface tension, providing high adhesion of subsequent organic coatings and respectively, significant increasing of their protective properties. The paper presents the results obtained in the investigation of combined anti-corrosion coatings, including formation of phosphate films on galvanized steel surfaces followed by the application of three types of paint and varnish coatings. The indicators characterizing the phosphating preparation (density, ph, conductivity, acid capacity) as well as the thickness of the coatings were measured. The chemical composition of the phosphate films, their morphology and topography were determined by means of eDX and SeM, respectively. The adhesion, elasticity and impact toughness of the organic coatings, with and without phosphating treatment of the zinc surfaces were measured. The corrosion resistance of the combined coatings in a model sodium chloride solution was also determined.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":"30 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135584165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tripropylene glycol diacrylate (TPGda) monomer which can potentially to increase the crosslink density of polymer blends is unstable in water due to its low water solubility properties. however, the stability of TPGda emulsion could be improved by adding an adequate amount of surfactant. This study addresses the effect of different Tween 20 (surfactant) concentration on emulsion stability of TPGda. Model emulsion ranging between 0.1 wt% to 3 wt% of Tween 20 and a control were prepared using heavy duty homogenizer. The emulsion was characterised by FTir, microstructure analysis, phase separation observation and creaming index during storage time. Emulsion containing 0.4 wt% Tween 20 showed the longest stability at 24 hours and a creaming index of 0%, which is enough for an ideal emulsion. The FTir spectra displayed the interaction of TPGda and Tw-20, proving that the emulsion is fully mixed and stabilized. The results are further supported by optical microscopy, which observed no droplet aggregation and flocculation in the TPGda emulsion with the presence of 0.4 wt% of Tw-20 surfactant. This information about Tw-20 is beneficial, making it a promising surfactant for enhancing the emulsion stability of the TPGda emulsion.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":"31 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135584159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
