Composite Coating Structure for Durability Enhancement of Flexible Devices 

Over the recent years, demand for flexible devices has grown rapidly in various technological applications including wearable computers, flexible displays and solar cells. Because these devices are typically packaged with polymeric materials, they are prone to physical damage due to contact and bending stresses experienced during usage. Thus, mechanical durability becomes an important issue to overcome to achieve sufficient reliability for commercialization of flexible devices. In this presentation, coating structures in the form of a composite that may be utilized for flexible device applications are discussed. The effectiveness of a discrete coating structure that allows for sufficient light transmission as well as flexibility is presented. Rather than using a continuous coating, the concept is to use a discretely structured coating so that large angle bending is allowed without causing excessive tensile stress to accumulate within the coating. Also, the flexible property of thin materials is exploited to achieve adequate flexibility with good surface durability. It is expected that surface durability of polymeric flexible materials will be greatly enhanced by using these types of composite coating structures.

Using Ultrasound to Measure the Buried Interface  

Machine elements, like bearings, seals, gears, and piston rings are at the heart of machines. Getting access to them to study how they perform is challenging. One way to measure the ‘buried interfaces’ is to use pulses of sound. Ultrasound will penetrate through machine parts and reflect from tribological interfaces. If we choose the right sensors, and put them in the right place, we can measure oil film thickness, viscosity, load, and contact in the interface. This talk will explain the underlying physical principals and give examples from car engines to wind turbines.

Molecular behaviour in thin film lubrication

The behaviour of lubricant molecules, especilly the molecules near the solid surface is very important to the property of the whole tribo-system. However, how do the liquid molecules behave in a nano-confined space, especially in a nano lubricant film? Thin film lubrication (THL) theory has been invoked to characterize the molecular pattern in lubrication film less than hundred nanometers, which effectively bridged the gap between elastohydrodynamic lubrication (EHL) and boundary lubrication. Unfortunately, to date, the molecular model of TFL which was proposed 20 years ago has not been well proven. Recently a novel method based on surface-enhanced Raman spectroscopy developed in our group allows us to access the molecular behavior in a nano-confined film, along with both the packing and orientation of the liquid molecules in TFL regime. The presentation attempts to systematically review the major developments of TFL, including the state-of-art studies on experimental technologies, researches and applications. Future prospects of relevant researches and applications will be also discussed.

Engineering Ceramics and Their Composites - Tailoring Material Variables for Tribological Application  

This presentation will provide an overview of the experimental results from our groups, where we will demonstrate the microstructure-toughness-wear correlation in some of the model ceramic systems. Specific examples of the case studies from our own research will be provided to demonstrate how humid atmosphere or high temperature environment influence the wear properties of structural ceramics of cutting tool cermets, respectively. Towards the end of the presentation, some interesting and recent experimental results on cryogenic wear of brittle ceramics will be presented. In order to demonstrate the tribological properties of ceramics in cryogenic environment, the results of a planned set of sliding wear tests on self-mated Al2O3, ZrO2 and SiC in liquid nitrogen will be discussed. A comparison will also be made with the results of some control experiments carried out at ambient conditions.
