Electrofragmentation modeling of conductive coatings on polymer substrates

Characterization of SiO2-TiO2 Coatings on 316l Stainless Steel Substrates

This paper reports nano-structured SiO2-TiO2 coatings using the sol-gel technique on 316L steel substrates. Nanoindentation, surface analysis and corrosion resistance tests were performed on different samples. The nanomechanical tests allowed to compare uncoated steel samples (Eavg = 193.24 GPa and mean hardness of 2.63 GPa and coated steel samples (Eavg = 287.38 GPa and mean hardness of 5.74 G...

Modelling the effect of temperature on crack onset strain of brittle coatings on polymer substrates

a r t i c l e i n f o The effect of temperature on the crack onset strain (COS) of brittle coatings on polymer substrates was investigated through a series of temperature-controlled tensile tests carried out in situ under an optical microscope. It was observed that the failure of such materials under tensile strain was strongly affected by temperature, but the exact behaviour was heavily depend...

PVD coatings on aluminium substrates

It is well known that aluminium is today the most widely used metallic material besides steel. The mechanical characteristics of aluminium offer an increasing application field, especially where lightweight constructions are required. The demands for improved characteristics such as higher strength and greater durability are achieved by the development of new aluminium alloys. Continuous effort...

Modeling and Data Analysis of Conductive Polymer Composite Sensors

MODELING AND DATA ANALYSIS OF CONDUCTIVE POLYMER COMPOSITE SENSORS Hua Lei Department of Chemical Engineering Doctor of Philosophy Conductive polymer composite sensors have shown great potential in identifying gaseous analytes. To more thoroughly understand the physical and chemical mechanism of this type of sensors, a model was developed by combining two sub-models: a conductivity model and a ...
