We have investigated the sliding friction behavior of metallic couples with different enthalpy of mixing or reaction by friction force microscopy. Comparing the friction behavior of miscible and immiscible couples we find that in the first case friction is governed by adhesion while the shear strength is low (τ = 3–6 MPa). In the latter case of immiscible(More)
The nano-sized defects in the barrier layer are considered as major pathway of water vapor. In this paper, Cr thin film was coated on the polyethylene terephthalate (PET) substrate. By application of atomic layer deposition (ALD) with an Al<sub>2</sub>O<sup>3</sup> on the Cr thin film having nano-sized defects, a direct image of the nano-sized defects was(More)
