To overcome this, the present study proposed the use of h-BN nanoparticles as an additive with MIL-PRF-23699 grade lubricant. To improve the stability and suspension of the h-BN nanoparticles in the NL, the NL was prepared with h-BN nanoparticles and various surfactants. The properties were evaluated for both BL and NL. The tribological experiments were carried out using a four-ball tester, a shear stability tester, and a Reichert tester. The h-BN NL resulted in a 16% reduction in WSD when compared with the BL. The LWI of h-BN NL was increased by 7.44% compared with BL. In the shear stability test, h-BN NL showed 93% better shear stability than the BL. The CoF was reduced by 13% with the h-BN NL in the Reichert test. The experimental results indicated that the h-BN nanoparticles with MIL-PRF-23699 grade lubricant had better tribological properties for aerospace applications.","PeriodicalId":23315,"journal":{"name":"Tribology Transactions","volume":"66 1","pages":"882 - 894"},"PeriodicalIF":2.1,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42433881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore the selection of friction pair materials, this paper investigated the tribological properties of CFRPEEK, stainless and carbon steel in water and high water-based fluids, and evaluated them using reciprocating friction and wear tester. After the test, the wear surface morphology of the contact surface was observed under an electron microscope. The results show that the degree of friction between specimens is dependent on the load and frequency. Meanwhile, both 316L and CFRPEEK have good tribological properties in both mediums. Microscope observation analysis showed that CFRPEEK surfaces easily absorb water to create a water film, thus improving its performance and reducing wear. Additionally, the friction between stainless and carbon steel in high water-base fluid will generate a lubricating film, the surface of which shows excellent tribological properties. The final conclusion was that the choice of material for plunger pair material depends on the medium, with 304-316L being more suitable for high water-based fluids, while CFRPEEK-316L is more suitable for water.","PeriodicalId":23315,"journal":{"name":"Tribology Transactions","volume":"66 1","pages":"895 - 905"},"PeriodicalIF":2.1,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45257649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, an effective response strategy for reducing the frequency of abnormal wear of the arch network has not been achieved. In this article, the friction and wear properties of pure carbon and copper-impregnated carbon skateboards are used to investigate and compare the friction properties under different working conditions. The experimental results show that the contact resistance of the pure carbon skateboard/contact wire increases from 12 mΩ to 45 mΩ with increasing current and shows an overall low friction coefficient. The contact resistance of the copper-impregnated carbon skateboard/contact wire fluctuates in the range of 4 mΩ to 16 mΩ, with a relatively high friction coefficient. A high current density accelerates the electrical wear behavior and temperature increase of the interface of the pure carbon skateboard/contact wire. A matching strategy of carbon skateboard and contact wire is proposed by comparing the friction coefficient, contact resistance, and wear rate.","PeriodicalId":23315,"journal":{"name":"Tribology Transactions","volume":"66 1","pages":"832 - 844"},"PeriodicalIF":2.1,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48432245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ball–cage impact forces and cage-guiding ring forces are also considered, leading to a set of six dynamic differential equations to consider for each ball and three dynamic differential equations for the cage, where movement is assumed to be restricted to one plane. Quasi-static calculations can be undertaken by neglecting the cage and setting the accelerations of each degree of freedom of the ball to zero. New analytical or curve-fitted models are also provided using the mean values of sliding speed and viscosity to calculate sliding forces and moments, avoiding the use of contact slices with some useful relationships derived for calculating the rolling line locations, bearing torque, and dissipated bearing power. Several examples of calculated results are given and compared to available numerical or experimental results published in the literature. Finally, a new tool developed in-house is proposed for predicting many properties, particularly of interest at high speed, including the ball bearing torque, power loss, risk of smearing, and risk of cage failure.","PeriodicalId":23315,"journal":{"name":"Tribology Transactions","volume":"66 1","pages":"845 - 868"},"PeriodicalIF":2.1,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44393455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, a test rig for the windage power loss of spiral bevel gear under oil-jet lubrication is established, and on this basis, a method for measuring windage torque is proposed. Next, the interactive effects of different injection lubrication parameters on the windage power loss were studied by orthogonal experiment, and the formula for calculating the windage loss was obtained by fitting the experimental data. Then, the fluid distribution, velocity field and pressure field around the gear were analysed by using a computational fluid dynamics (CFD) numerical model, and the mechanical and energy characteristics of the gear windage power loss were obtained. Finally, the dimensionless processing of the windage moment was carried out, and the variation of the dimensionless windage moment coefficient with the rotational Reynolds number is obtained. The comparison between the dimensionless windage moment coefficient of experimental data and simulation results shows that the CFD values are in good agreement with the measured data. This study provides experimental and methodological guidance for the calculation of windage power loss and windage reduction design of aviation gear pair under oil injection lubrication.","PeriodicalId":23315,"journal":{"name":"Tribology Transactions","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44230894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
