Replacement of a Multi-function Tribometer

大量的能量用于克服摩擦，主要的经济损失是由于产品和部件的磨损及其更换。通过改进摩擦控制可以节省大量费用，润滑是控制磨损和减少摩擦的有效手段。摩擦学是一门多学科的科学，应用于摩擦，磨损和润滑涉及到移动接触。摩擦磨损试验机是一种测量不同材料的摩擦/润滑性和磨损的仪器。自2012年以来，Grecov一直使用具有基本配置的Nanovea T50摩擦计，该摩擦计是通过NSERC RTI赠款购买的。目前，申请人正在申请资金，用多功能Nanovea T100摩擦计取代现有的摩擦计。尽管T50摩擦磨损试验机仍可用于初始评估，但不能用于涉及所有主要润滑状态的更高级研究，并且其仅限于2至20 N之间的载荷。Nanovea公司不再提供现有的Nanovea T50摩擦计和替换零件，该公司正在提供以旧换新，以T100版本替换过时的型号。Grecov的研究计划得到了NSERC发现基金的支持（“纳米分散体在润滑和生物润滑中的新应用”），将能够继续增加T100摩擦计。该研究计划预计将导致先进的预测工具，以提高对纳米润滑机制的理解，并从长远来看，为大量的工业和生物医学应用提供新的，经济上可行的，高性能的环保纳米润滑剂。该设备还将使Grecov的团队能够研究添加到纳米颗粒（如纤维素纳米晶体（CNC）和氧化石墨烯（GO）和/或液晶）中的合成油和植物油的润滑作用。新的T100多功能摩擦计还将使透明质酸溶液和CNC的粘性补充剂的开发能够治疗骨关节炎（OA），从而改善OA患者的生活质量。所要求的设备将使Grecov和克兰斯顿通过NSERC联盟资助的项目以及与Anomera Inc.的持续合作，就水性悬浮液中羧化CNC的润滑性能进行合作。巴斯夫此外，摩擦计将有利于其他研究伙伴关系，重点是使用纳米纤维素代替塑料作为化妆品和家用清洁产品的微珠，并使用纳米纤维素作为食品，化妆品和药品的凝胶和乳液中的稳定剂，其中流变学，触觉感知和润滑是关键性能指标。 福斯特的研究是从叶提取物中开发疏水涂层，这种涂层可以通过热活化重结晶成空心棒，这需要这里要求的摩擦学设备来测试性能和耐久性。

A vast amount of energy is spent to overcome friction, and major economic losses are due to wear of products and components, and their replacement. Considerable savings can be made by improved control of friction, and lubrication is an effective means of controlling wear and reducing friction. Tribology is a multidisciplinary science applied to friction, wear, and lubrication involved at moving contacts. Tribometer is an instrument for measuring the friction/lubricity and the wear of different materials. Since 2012, Grecov has used the Nanovea T50 tribometer with a basic configuration, which was purchased with an NSERC RTI grant. Currently, the applicants are requesting funding to replace the existing tribometer, with a multi-function, Nanovea T100 tribometer. Although still usable for initial evaluations, the T50 tribometer cannot be used for more advanced studies involving all of the main lubrication regimes and it is limited to loads between 2 and 20 N. The existing Nanovea T50 tribometer and replacement parts are no longer being supplied by the Nanovea company, which is offering a trade-in to replace the obsolete model with the T100 version. Grecov's research program, supported by the NSERC Discovery Grant ("Novel applications of nanodispersions in lubrication and bio-lubrication") will be able to proceed with the addition of the T100 tribometer. The research program is expected to lead to advanced, predictive tools to improve the understanding of nano-lubrication mechanisms, and in the long-term, to present new, economically viable, high performance environmentally-friendly nanolubricants for a large number of industrial and biomedical applications. The equipment will also enable Grecov's team to study lubrication with synthetic and vegetable oils added to nanoparticles, such as cellulose nanocrystals (CNC) and graphene oxide (GO) and/or liquid crystals. The new T100 multi-function tribometer will also enable the development of a viscosupplement from hyaluronic acid solution and CNC to treat osteoarthritis (OA), thereby improving the quality of life of OA patients. The requested equipment will enable a collaboration between Grecov and Cranston on the lubrication performance of carboxylated CNCs in aqueous suspension through an NSERC Alliance funded project and an ongoing collaboration with Anomera Inc. and BASF. Additionally, the tribometer will benefit other research partnerships focused on using nanocellulose in place of plastics as microbeads for cosmetics and household cleaning products, and using nanocellulose as stabilizers in gels and emulsions for food, cosmetic and pharmaceutical products where rheology, tactile perception and lubrication are key performance metrics. Foster's research on the development of a hydrophobic coating from leaf extracts, which could be recrystallized into hollow rods through heat activation, would require the tribological equipment requested here, to test the performance and durability.
