The effects of different Al\/Ni ratios on the microstructures of NAB are investigated using a metalloscope, scanning electron microscopy, transmission electron microscopy, and XPS analysis. The mechanical property is evaluated with microhardness testing and tensile mechanical testing. The corrosion resistance is evaluated using mass-loss testing, electrochemical testing, and corrosion-product characterization. The results show that with the increase of the Al\/Ni ratio, the content of precipitated phases increases, while \u03b2\u2032 and hard \u03ba, which have a different morphology, appear. As the Al\/Ni ratio rises from 1 to 2.5, the hardness increases from 104 HV to 202 HV, and the tensile strength increases by 394 MPa from 356 MPa to 751 MPa, but the elongation decreases substantially from 50.50% to 11.00%. The best corrosion resistance is shown on ZCuAl7-7-4-2, with a corrosion rate of 0.00267 mm\/a after 30 d of static immersion corrosion in 3.5 wt.% NaCl solution. Through electrochemical testing and corrosion-product characterization, it is found that ZCuAl7-7-4-2 has the largest polarization resistance Rp, and the selective corrosion of the surface is mild.<\/jats:p>","DOI":"10.3390\/ma17061330","type":"journal-article","created":{"date-parts":[[2024,3,14]],"date-time":"2024-03-14T05:43:08Z","timestamp":1710394988000},"page":"1330","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Effect of Al\/Ni Ratio on the Microstructure and Properties of Nickel\u2013Aluminum Bronze Alloys"],"prefix":"10.3390","volume":"17","author":[{"given":"Yinxun","family":"Tan","sequence":"first","affiliation":[{"name":"State Key Laboratory of Nonferrous Metals and Processes, China GRINM Group Co., Ltd., Beijing 100088, China"},{"name":"GRIMAT Engineering Institute Co., Ltd., Beijing 101407, China"},{"name":"General Research Institute for Nonferrous Metals, Beijing 100088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4832-6400","authenticated-orcid":false,"given":"Haofeng","family":"Xie","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Nonferrous Metals and Processes, China GRINM Group Co., Ltd., Beijing 100088, China"},{"name":"GRIMAT Engineering Institute Co., Ltd., Beijing 101407, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xue","family":"Feng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Nonferrous Metals and Processes, China GRINM Group Co., Ltd., Beijing 100088, China"},{"name":"General Research Institute for Nonferrous Metals, Beijing 100088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3734-5427","authenticated-orcid":false,"given":"Shuhui","family":"Huang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Nonferrous Metals and Processes, China GRINM Group Co., Ltd., Beijing 100088, China"},{"name":"GRIMAT Engineering Institute Co., Ltd., Beijing 101407, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjing","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Nonferrous Metals and Processes, China GRINM Group Co., Ltd., Beijing 100088, China"},{"name":"GRIMAT Engineering Institute Co., Ltd., Beijing 101407, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijun","family":"Peng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Nonferrous Metals and Processes, China GRINM Group Co., Ltd., Beijing 100088, China"},{"name":"GRIMAT Engineering Institute Co., Ltd., Beijing 101407, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wanyu","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Nonferrous Metals and Processes, China GRINM Group Co., Ltd., Beijing 100088, China"},{"name":"GRIMAT Engineering Institute Co., Ltd., Beijing 101407, China"},{"name":"General Research Institute for Nonferrous Metals, Beijing 100088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yizhi","family":"Zhao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Nonferrous Metals and Processes, China GRINM Group Co., Ltd., Beijing 100088, China"},{"name":"GRIMAT Engineering Institute Co., Ltd., Beijing 101407, China"},{"name":"General Research Institute for Nonferrous Metals, Beijing 100088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"111656","DOI":"10.1016\/j.corsci.2023.111656","article-title":"Suitability of nickel aluminium bronze alloy fabricated by laser powder bed fusion to be used in the marine environment","volume":"226","author":"Arcos","year":"2024","journal-title":"Corros.
