A titanium nitride (TiN) coating was deposited by magnetron sputter ion plating onto steel and titanium alloy polished substrates. The adhesion of the coating on each substrate material was investigated using a newly developed multimode scratch teste

The mico-scale abrasion test has become very popular in recent years for the measurement of the abrasive wear of coatings and other materials. A EU-funded project has just been completed that had the aim of developing the test method, and revising th

The microstructure evolution induced by hydrogen absorption in the ZrNi compound was investigated during the activation process. A rigorous control of the thermodynamic parameters during the hydride phases growth allowed to prepare two samples of ove

The ball cratering (micro-abrasion) test is becoming popular as a method for the abrasion testing of surface engineered materials. It possesses many advantages over more conventional abrasion tests including the ability to test small volumes of mater

The ZrNi–H2 phase diagram indicates the presence of two stable hydrides: a triclinic monohydride ZrNiH and an orthorhombic trihydride ZrNiH3 [1] . In this paper, we present the results of some thermodynamic, microstructural and electronic propertie

Ge was grown on sapphire (α-Al 2 O 3 single crystals) by molecular beam epitaxy. On the (0001) surface (basal plane) of sapphire as well as on the (11 2 0) surface (prism plane), Ge forms islands with a unique orientation relationship to the substra

The Burgers vector of very close intrinsic dislocations in a near-Σ = 11,{311} grain-boundary in nickel is identified using a geometrical method based on local and accurate measurements of the angular deviation from perfect coincidence Σ = 11 by la

A Σ = 11, {332} nickel bicrystal was grown by solidification. The aim of this paper is to show the evolution of the grain-boundary (GB) structure depending upon the position in the bicrystal of the extracted sample. Conventional transmission electro

A ∑ = 11 {332} Ni bicrystal was grown by solidification. The Grain Boundary (GB) atomic structure studied by high resolution electron microscopy (HREM) has been shown to depend upon the position in the bicrystal of the extracted sample. Strongly co

The relaxation of stresses associated to extrinsic grain-boundary dislocations (EGBDs) in singular Σ = 3, {111}, in vicinal Σ = 11, {311} and in general Σ = 11, {332} grain boundaries (GBs) has been investigated by in-situ transmission electron mi
