This paper presents measurements and cutting tests related to coating features on sharp cutting edges and rounded objects. One typical feature of plasma based deposition processes is the formation of a sheath region around the object to be coated. Th

With modern X-ray diffraction refinement methods it was possible to identify the first phase in the Mg–Cr–H system, Mg 3 CrH ∼6 from minute sample volume in spite of poor crystallinity and coexisting impurity phases. The new hydride was synthes

Structural stability and bonding properties of the hydrogen storage material Mg(2)NiH(4) (monoclinic, C2/c, Z = 8) were investigated and compared to those of Ba(2)PdH(4) (orthorhombic, Pnma, Z = 8) using ab initio density functional calculations. Bot

An irreversible conductor-insulator transition has been observed when heating Mg2NiH4 in the temperature interval 110 to 570 K. The disappearance of the electric conductivity is concomitant with the appearance of stacking faults (or microtwinning) in

In an attempt to destabilize Mg 2 NiH 4 , the starting alloy, Mg 2 Ni, was doped with aluminium by ball milling before hydrogenation. The structure of Mg 2 NiH 4 is based on an electron-rich d 10 [NiH 4 ]-complex stabilized by a Mg ion framework and

The synthesis of new ternary hydrides in the Mgx MnyHz-system (x:y = 1, 2, 3, or 4:1) was investigated by applying high pressures. Powder mixtures of magnesium hydride and manganese were pressed into a pellet and compressed at a pressure of 6 gigapas
