The performance and service life of Nitinol components are strongly influenced by the process chain and the associated manufacturing parameters. However, existing studies often focus on the effects of individual steps in the process chain, overlooking the combined impact of multiple steps on the material’s properties. In this context, the study explores the combined effects of additive manufacturing, heat treatment, and cryogenic machining on the wear performance of a Ni-rich Nitinol alloy. The material was systematically assessed in its as-built and heat-treated conditions for microstructure, transformation temperatures, nano-hardness, superelasticity, and surface roughness. Key findings show that heat treatment following additive manufacturing significantly enhanced the superelasticity and mechanical strength of the alloy, underlining the importance of heat treatment after additive manufacturing of Ni-rich Nitinol. On the contrary, the cryogenic machining step reduced the material superelasticity, with the influence of the cutting speed to be taken into account. Wear tests further demonstrate the superelasticity effect in assessing Nitinol’s wear resistance, with surface roughness also playing a significant role. The study underscores the potential of heat-treated NiTi in applications requiring high mechanical strength, wear resistance, and superelasticity, such as biomedical devices and aerospace components.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"204 ","pages":"Article 110478"},"PeriodicalIF":6.1,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143158533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alloys that resist frictional ignition tend to grow a thick, protective oxide tribolayer during sliding. Ignition occurs when this tribolayer breaks down, exposing the hot underlying metal to oxygen. This paper establishes a quantitative link between frictional ignition and tribolayer breakdown using thermal ignition theory. The tribolayer breakdown mechanisms that drive frictional ignition of several engineering alloys are determined experimentally. For the alloy Haynes 214, the dominant tribolayer breakdown mechanism transitions from melting of the underlying metal to mechanical failure as oxygen pressure decreases, demonstrating how operating conditions affect ignition behavior. Thermal ignition theory is used to determine a critical interfacial temperature above which an alloy ignites in the absence of an oxide tribolayer. For the alloys of present interest, this critical temperature is lower than both the interfacial temperature at ignition (when the tribolayer breaks down) and the alloy melting point. In the temperature range between the critical and ignition temperatures, the sliding contact is metastable, meaning ignition occurs if the tribolayer is disturbed. Ignition resistance can be improved by raising the critical temperature towards the alloy melting point through changes in component design, operating conditions, and material properties. Additionally, tailoring alloy chemistry to promote the growth of a breakdown-resistant tribolayer allows safe operation in the metastable regime.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"205 ","pages":"Article 110484"},"PeriodicalIF":6.1,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
