GFBR systems have a wide range of high-speed turbomachinery applications. Due to the high speed, these machines are susceptible to rigorous vibration and instability. Gas foil bearings instigate large amplitude of vibrations at startup and shut down and severe subsynchronous motions during high-speed operations. Over the years, numerous work has been done in the field of high-speed rotors supported on gas foil bearings. Significant improvement has been observed in the stability and feasibility of the GFBR systems. However, accurate model predictions of gas foil bearing still remain a challenge for its widespread usage in high-speed turbomachinery. A comprehensive review needs to be done to study the previous work and pave the way for future research. The current review is majorly divided into three sections. Firstly, various models used for the performance prediction of gas foil bearings are compiled. After that, major causes of instability that manifest during the experiments and practice with gas foil bearing supported rotors is illustrated. Lastly, the developmental attempts made to inhibit the instability is summarised. This paper presents an overall picture of the current engineering scenario and future prospects of the GFBR systems.","PeriodicalId":23320,"journal":{"name":"Tribology in Industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44321364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, 3D printing has progressed remarkably and is expected to proceed in numerous applications, such as automotive, medical, wind turbine, and aerospace applications. 3D printing technology opens the door to enhancing and optimizing several applications. Although of such advancement, there is still a lack of the tribological research investigations in this area. This work is devoted to studying the tribological properties of 3D printed polymers (ABS, PLA, Co-polyester, and PCL) for utilization in a wide range of applications, such as medical, automotive, and various tribological applications. The test specimens were printed using fused deposition modeling (FDM) technology. The tribological characteristics of 3D printed specimens were evaluated using a pin-on-disc tester. Vicker's hardness tester was used to determine the specimens' hardness. Scanning electron microscopy (SEM) with backscattering was used to examine the worn surfaces of samples. Based on the findings of the current investigation, it was discovered that 3D printing technology enhanced the bonding strength and wear resistance of the tested specimens. Furthermore, the 3D-printed polymers (ABS, PLA, Co-polyester, and PCL) produced varying friction coefficient (high and low) values at acceptable wear resistance making them suitable for a wide range of applications. The samples that were printed using PLA and co-polyester had the lowest coefficients of friction (0.3) while the samples that were printed using ABS and PCL had the greatest coefficients of friction (0.4) and (0.39) respectively.","PeriodicalId":23320,"journal":{"name":"Tribology in Industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45581661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study seeks to examine the effects of commercial compressor oil-SAE30, and its blend with pentaerythritol ester (PE) derived from vegetable oil on tribological properties. Two sequential transesterification processes were used to create the pentaerythritol ester made from vegetable oil utilizing the ultrasonic irradiation method. Using an air compressor lubricant, load, and sliding speed for each experimental run, a pin-on-disc tribometer is utilized to examine the friction and wear characteristics of the material. According to the experimental findings, PE 75 (75 vol.% - PE and 25 vol.% - SAE30) performs better than PE and SAE30 in terms of minimum coefficient of friction (COF) and specific wear rate (SWR) under high loads and high sliding speeds. Furthermore, scanning electron microscope (SEM) and Energy Dispersive Analysis of X-Ray (EDAX) analyses were used to examine the morphology behavior of the pin surfaces. Due to the coating that covers the specimen's surface, PE 75 compressor oil displays smoother surfaces than other lubricated surfaces.","PeriodicalId":23320,"journal":{"name":"Tribology in Industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48427478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current research is directed towards less invasive procedures for treating this degenerative disease using tissue engineering and 3D bioprinting. Therefore, it is crucial to obtain the exact shape of the damaged tissue, reconstruct the original shape of the tissue, and estimate the volume and area resulting from the wear of the contact surfaces. The study used the tibial plateau of a patient with OA that was removed during total knee arthroplasty, and the data was collected using a 3D scanner. After the reconstruction of the tibial plateau, an assessment of the area and volume of wear on the medial condyle of the tibia was performed, along with a FEM analysis of the real and approximate shape of the cartilage tissue. In this way, it is possible to simulate and create a patient-specific 3D model with a reconstructed wear volume, which can be highly attractive for future treatment strategies for cartilage damage or early stages of OA.","PeriodicalId":23320,"journal":{"name":"Tribology in Industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47965309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Secondary reinforcements provide safe disposal of agro-industrial waste thereby reducing environmental degradation. The scanning electron micrographs reveals fairly uniform dispersal of reinforcement in metal matrix if proper conditions are maintained and porosity levels are found to be in acceptable range. The density, hardness, wear resistance, tensile strength, fatigue strength and impact strength of non-ferrous composites have been found to be either comparable or superior to an unreinforced alloy with minimum weight and cost. The purpose of current study is to explore the nonferrous composites and propose their application area based on material properties. An attempt has been made for indepth review on the effect of controllable process parameters on tribo-mechanical properties of the non-ferrous composites. The study concludes that non- ferrous composites with single or more than one reinforcement have superior tribo-mechanical characteristics making them suitable for design of high performance, low cost and low weight to strength ratio components.","PeriodicalId":23320,"journal":{"name":"Tribology in Industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41275213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cladding, a type of surface modification process, is used to create layers on titanium and its alloys that have superior mechanical qualities, wear characteristics, oxidation resistance at high temperatures, and good biocompatibility. Material selection is critical for achieving the increased qualities mentioned above, in addition to various cladding techniques and associated process parameters. A review of the outcomes of various common wear-resistant cladding techniques applied to the titanium alloy surface is the subject of this study. The most important functional claddings in this domain are also presented and investigated in depth. The present issues and future initiatives are also discussed, with an emphasis on identifying knowledge and technological gaps as well as attempting to establish future research possibilities. On this foundation, it is suggested that in the coming years, resistant-to-wear cladding with significant improvements in toughness and hardness should progress on the path of smart manufacturing techniques, optimising and precisely customising microstructural configurations, and developing numerical simulation techniques of cladding.","PeriodicalId":23320,"journal":{"name":"Tribology in Industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48386713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
