The effects of bombardment time on the microstructure, mechanical properties, and corrosion resistance of the gradient nanostructure were investigated. The results showed that the layer depth and surface roughness of the gradient nanostructures increased with an increase in the bombardment time, and the corresponding mechanical properties and corrosion resistance first increased and then decreased with an extension of the bombardment time. When the bombardment time was 30 s, the alloy had good mechanical properties and corrosion resistance. Its tensile strength, yield strength, elongation, and static corrosion rate were 299.1 ± 2.2 MPa, 264.4 ± 1.5 MPa, 36.8 ± 1.3 %, and 0.307 ± 0.015 mm y − 1 , respectively. The results of the 120-h immersion experiment in simulated human body fluids showed that the average corrosion rate of the alloy first decreased, then increased, and finally decreased with an extension of the immersion time and finally tended","PeriodicalId":49937,"journal":{"name":"Kovove Materialy-Metallic Materials","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72722028","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 microstructure of HCUS Cu-5wt.%Sn alloy was analyzed by optical microscope and scanning electron microscope. Meanwhile, numerical simulation software ProCAST was used to simulate the Sn distribution of HCUS Cu 5wt.%Sn alloy. The results show that there exists a serious exudation layer on the lower surface of the HCUS Cu-5wt.%Sn alloy, while there is almost no exudation layer on the upper surface of the alloy. The simulation results show that the solid-liquid interface in the center protrudes to the liquid during the HCUS process. A narrow gap is formed between the mold and the alloy. During solidification, Sn solute is precipitated from solid to liquid. Therefore, the liquid between dendrites has a low melting point and does not solidify at high mold temperatures. These liquids flow down into the gap due to gravity and solidify at the last stage, forming an exudation layer on the lower surface enriched by Sn solute.","PeriodicalId":49937,"journal":{"name":"Kovove Materialy-Metallic Materials","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78252315","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}
