The aim of this study is to determine the erosion characteristics of compressor blades and how it changes with time. Particle velocimetry and erosive experiments were conducted to obtain the SiO₂ particle velocity and the erosion rate of the Ti-6Al-4V titanium alloy. Based on the measured data, the parameters of the Tabakoff erosion model have been refined, which is critical for establishing a transient erosion model for the 1.5-stage compressor of a turboshaft engine that accounts for the effect of particle erosion time. Simulation results show that the motion behavior of particles exhibits changing patterns at different time intervals, which leads to variations in the erosion area and erosion rate of the compressor. The erosion area and rate on blades increase nonlinearly with time. In some locations, when erosion time increases, the erosion area and erosion rate also increase. While, in other locations, the erosion area and erosion rate hardly change with time. The maximum erosion rates increased by 27.3 %, 28.6 %, and 87.2 % for the guide blades, 42.9 %, 69.6 %, and 84.0 % for the rotor blades, and 69.0 %, 103.6 %, and 142.8 % for the stator blades at 0.50s, 0.75s, and 1.00s, respectively, in comparison to 0.25s.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"558 ","pages":"Article 205578"},"PeriodicalIF":5.3,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142357591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the microstructure analysis, the presence of additional austenite grains at high temperatures during dry machining results in an increase in hardness. On the other hand, cooling techniques including liquid nitrogen (LN₂), carbon Quantum dots with SQL (CD), and oil with small quantity lubrication (OSQL) produce larger ferrite grains, which lower hardness. According to residual stress analysis, the high temperatures during dry cutting result in increased strains, which are successfully mitigated by lubrication. The two-phase microstructure has a crucial influence in mechanical characteristics, as demonstrated by X-ray diffraction (XRD) studies, wherein finer grains improve surface polish but demand more energy. Measuring surface roughness (<em>Ra</em>) reveals that adhesion wears during dry machining raises <em>Ra</em>, while OSQL and LN₂ cooling lower <em>Ra</em> and improve surface quality. Tool performance is negatively impacted by high machining temperatures. Cutting temperatures and friction are greatly reduced by LN₂ cooling. Dry machining increases tool wear because of the high temperatures and absence of lubrication; OSQL and CD lower wear rates, while LN₂ offers the best protection for tools. Thinner, better-separated chips are produced by effective lubrication in OSQL and LN₂, while thicker, more deformed chips are produced by dry machining, according to chip morphology and thickness analyses. The study leads to the conclusion that super duplex steel's surface quality, tool life, and machinability can all be significantly enhanced by carbon quantum dots and cryogenic cooling.</p></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"558 ","pages":"Article 205575"},"PeriodicalIF":5.3,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142242734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
