Abstract

Currently, substantial adhesion wear frequently occurs in Zr alloy cold rolling, which not only affects the quality of product's surface, but shortens the mould's service life. In this paper, water-based lubricant was prepared by using ZnO as additive and hydroxyethyl cellulose (HEC) as dispersant. The tribological test results showed the friction coefficient decreased by a maximum of 84.6%, and the friction surface was smooth and flat, with essentially no wear. By analysing the friction area, it was found after ZnO entered the friction interface, HEC carried a hydrated molecular layer to form a stable lubrication film at the interface. This film worked with nanoparticles to reduce friction and wear, and is expected to prolong the service life of rolling dies.

羟乙基纤维素改善水基ZnO纳米颗粒锆合金冷轧润滑剂的摩擦学性能

目前Zr合金冷轧中经常出现大量的粘着磨损，不仅影响产品表面质量，而且缩短了模具的使用寿命。以氧化锌为添加剂，羟乙基纤维素(HEC)为分散剂，制备了水基润滑剂。摩擦学试验结果表明，摩擦系数最大降低84.6%，摩擦表面光滑平整，基本无磨损。通过对摩擦面积的分析，发现ZnO进入摩擦界面后，HEC携带水合分子层，在界面处形成稳定的润滑膜。该薄膜与纳米颗粒一起工作，减少摩擦和磨损，并有望延长滚动模具的使用寿命。

期刊介绍： Lubrication Science is devoted to high-quality research which notably advances fundamental and applied aspects of the science and technology related to lubrication. It publishes research articles, short communications and reviews which demonstrate novelty and cutting edge science in the field, aiming to become a key specialised venue for communicating advances in lubrication research and development. Lubrication is a diverse discipline ranging from lubrication concepts in industrial and automotive engineering, solid-state and gas lubrication, micro & nanolubrication phenomena, to lubrication in biological systems. To investigate these areas the scope of the journal encourages fundamental and application-based studies on: Synthesis, chemistry and the broader development of high-performing and environmentally adapted lubricants and additives. State of the art analytical tools and characterisation of lubricants, lubricated surfaces and interfaces. Solid lubricants, self-lubricating coatings and composites, lubricating nanoparticles. Gas lubrication. Extreme-conditions lubrication. Green-lubrication technology and lubricants. Tribochemistry and tribocorrosion of environment- and lubricant-interface interactions. Modelling of lubrication mechanisms and interface phenomena on different scales: from atomic and molecular to mezzo and structural. Modelling hydrodynamic and thin film lubrication. All lubrication related aspects of nanotribology. Surface-lubricant interface interactions and phenomena: wetting, adhesion and adsorption. Bio-lubrication, bio-lubricants and lubricated biological systems. Other novel and cutting-edge aspects of lubrication in all lubrication regimes.
