Designing hydrophobic, anti-soiling coatings for solar module cover glass: degradation mechanisms to avoid Open
In-depth XPS was used to identify the degradation mechanisms of hydrophobic coatings used for solar modules. Oxygen found in the central chain resulted in performance losses due to β chain scission in UV exposure, and hydrolyzation in duri…

The Role of Self-Assembled Monolayers in the Surface Modification and Interfacial Contact of Copper Fillers in Electrically Conductive Adhesives Open
Printing of electrical circuits and interconnects using isotropic conductive adhesives (ICAs) is of great interest due to their low-temperature processing and compatibility with substrates for applications in sensors, healthcare, and flexi…

Determination of residual stress and interface adhesion toughness of thin films by blisters Open
Circular blisters and telephone cord blisters (TCBs) can spontaneously occur in thin films under constant biaxial compressive residual stress. In this work, new mechanical models are used in conjunction with measurements of blister morphol…

On cooling rate dependent spallation behavior of α-alumina scale grown by oxidation Open
It is hypothesized that dynamic and non-uniform plastic relaxation occurs in α-Al2O3 scale on Fe-Cr-Al substrate during cooling from high temperature, and furthermore, that the non-uniformity of plastic relaxation is related to\n(1) the va…

Thin film properties by blister tests Open
With the measured geometry morphologies of telephone cord blisters (TCBs), that is, the local blister width and height, and the global wavelength, a mechanical model is built to determine the residual compressive stress in thin films and i…

On spallation of EB-PVD thermal barrier coatings on turbine blades Open
Room temperature blistering and spallation failures reduce the life time of thermal barrier coatings (TBC). Based on the theory of pockets of energy concentration, a mechanical model for the multilayer circular blister is presented, consid…

The mechanics of interface fracture in layered composite materials: (6) spallation of thermal barrier coatings of turbine blades Open
It is consensus that local spallation failures in thermal barrier coatings (TBCs) are determined synergistically by many factors. The present experimental test results confirm a completely new spallation failure mechanism for the electron …
