The inhibitor’s anticorrosion properties are studied in neutral 3.5 wt.% naCl medium by anodic polarization, Tafel polarization, electrochemical impedance spectroscopy (EiS) and OCP exposure. The surface characterization is analyzed by Contact angle(Ca) measurement, X-ray photo-electron spectroscopy (XPS), and scanning electron microscopy(SEM). The electrochemical tests show that they can act as single inhibitor to form a passive layer to resist Cu corrosion, and the anticorrosion properties of Cu can be improved by using binary Hyamine 1622/BTaH inhibitors. XPS results indicate that both BaTH and Hyamine 1622 molecule can be chemisorbed onto the copper surface and make complex films with Cu species. Ca measurement revealed the enhancement of hydrophobicity by combining QSa with BTaH. OCP exposure in neutral medium for 72 h evidently reveals that the passive layer formed by binary inhibitors decreases the pit corrosion. Better hydrophobic nature and more compact passive layer give rise to excellent inhibition properties of binary inhibitors.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":"120 5","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138959668","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}

During the interaction disturbance of ultraviolet radiation, atoms are knocked out of the polymer chains, thus breaking the macromolecules, which leads to the disturbance in the structural stability of the materials. the standardised test samples obtained using the injection moulding method were subjected to the degradation process in natural and accelerated conditions in the UV test device. the degradation process in laboratory conditions was carried out during 750 hours with the use of lamps with a wavelength of 313 nanometers and an irradiation level of 0.76 w/m 2 , which corresponds to a period of 2 years in natural conditions. Using of thermogravimetric tGA and differential scanning calorimetry DsC analysis, the influence of energy applied from lamps and the energy reaching the earth’s surface on the change of melting enthalpy ∆ H m , quantitative index of the crystalline phase and the temperature of phase changes were determined.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":" 4","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138959985","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}

Electrochemical impedance measurements show that the addition of 35 ml/l h 3 Po 4 to the zinc electrolyte can increase impedance resistances of the DSa mesh anodes. cyclic voltammogram studies (cV) at a scan rate of 5 mV/s without agitation show that the oxidation peak in the solution with 35 ml/l phosphoric acid addition is highest, followed by that with 17 ml/l phosphoric acid addition and that without addition of phosphoric acid.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":" 4","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138962059","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}

To reduce the residual stress and surface roughness of 2a12 aluminum alloy, optimized milling parameters were obtained. To further reduce the milling residual stress of 2a12 aluminum alloy, the samples processed by the optimized milling parameters were treated by cryogenic treatment and artificial aging. The residual stress of the sample was measured by the blind hole drilling method, and the evolution mechanism of the microstructure to reduce the machining residual stress was revealed. The results show that the combination of deep cooling treatment and oil bath aging can effectively reduce the residual stress on the machined surface of the aluminum alloy and facilitate a more uniform distribution of the residual stress inside the specimen. The effect of the coarse second phase on the residual stress in the microstructure is not significant, and the fine and diffusely distributed precipitation phase is beneficial to the reduction of the residual stress in the aluminum alloy.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":"30 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":"135584171","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}
