A study is made of the factors that contribute to the energy of mica-mica, silica-silica, and mica-silica interfaces in the presence of moist atmospheres. Energies are measured using brittle fracture and contact adhesion techniques. Both “virgin” and “healed” interfaces are investigated, with special attention on the latter. The fracture and adhesion data overlap, reflecting a common underlying separation process by “sharp-crack propagation.” The study identifies several contributors to the… 
Role of internal friction in indentation damage in a mica-containing glass-ceramic
The indentation response of a mica-containing glass-ceramic that exhibits shear-driven yield in an indentation test is interpreted in terms of events occurring on the microstructural scale. It is
Deformation and fracture of mica-containing glass-ceramics in Hertzian contacts
The Hertzian indentation response of a machinable mica-containing glass-ceramic is studied. Relative to the highly brittle base glass from which it is formed, the glass-ceramic shows evidence of
Cohesion of Amorphous Silica Spheres: Toward a Better Understanding of the Coagulation Growth of Silicate Dust Aggregates
Adhesion forces between submicrometer-sized silicate grains play a crucial role in the formation of silicate dust agglomerates, rocky planetesimals, and terrestrial planets. The surface energy of
Role of interfacial water in adhesion, friction, and wear—A critical review
Surficial water adsorption and interfacial water condensation as natural phenomena that can alter the contact status of the solid interface and tribological performances are crucial in all length
Pressurized internal lenticular cracks at healed mica interfaces
The equilibrium states of internal penny cracks at interfaces in thin-sheet bodies are investigated. Consideration is given to cracks held open by a center-loading force from an entrapped particle in
The Adhesion of Mica Nanolayers on a Silicon Substrate in Air
Mica nanolayers (MNL) are a new dielectric material that can improve the electron transport properties of Si based microelectronic devices. However, the mechanical reliability of such devices is not


Interfacial energy states of moisture-exposed cracks in mica
Results of crack growth observations on mica in water-containing environments are described. The study focuses on equilibrium crack states for reversed loading cycles, i.e., for initial propagation
Friction and Adhesion of Clean and Contaminated Mica Surfaces
In order to determine the shear strength of boundary lubricants it is essential to use a substrate which is smooth on a molecular scale. An apparatus is described in which it is possible to apply
Closure and Repropagation of Healed Cracks in Silicate Glass
Cracks in soda-lime-silica and vitreous silica glass close against a finite load at humidities between 0.01% and 100%. The force associated with crack closure (0.15 J/m/sup 2/) can be predicted by a
Thresholds and reversibility in brittle cracks: An atomistic surface force model
A new picture of environmentally-enhanced fracture in highly brittle solids is presented. It is asserted that the fundamental relations for crack growth are uniquely expressible in terms of the
Adhesion of silicates cleaved in ultrahigh vacuum
The adhesions between various silicate minerals cleaved in an ultrahigh vacuum (1 to 4 × 10−10 torr) are compared with the adhesions between the same minerals cleaved in air at atmospheric pressure.
Surface Forces and Adhesion Between Dissimilar Materials Measured in Various Environments
The Israelachvili surface force apparatus has been used extensively over the past decade to make detailed measurements of surface forces and adhesion between very smooth solids in various liquid and
Splitting of Mica Crystals and Surface Energy
Abstract The splitting of mica is a complex non-equilibrium process followed by: the stretching of the surface layers till the adhesion forces are broken; the electrification of the surface caused by
