The use of magnesium alloys is limited due to their susceptibility to corrosion although they have many attractive physical and mechanical properties. To increase mechanical and corrosion properties of these alloys, many deposition method and coating types are used. Electroless Ni–B coatings have received considerable interest recently due to its unique properties such as cost-effectiveness, th...

The influence of Co (Ni) and B co-doping on the structural, magnetic and magnetocaloric properties of (Mn,Fe) 2 (P,Si) compounds is investigated by X-ray diffraction (XRD), differential scanning calorimetry, magnetic and direct temperature change measurements. It is found that Co (Ni) and B co-doping is an effective approach to tune both the Curie temperature and the thermal hysteresis of (Mn,F...

Ni-B binary coating and Ni-B-W ternary were successfully prepared on titanium alloy (TC4) substrates by electroless plating to improve the hardness wear resistance, followed annealing treatment for better mechanical properties tribological properties. The morphology, composition, microstructure, properties, behaviors of coatings characterized. Both as-plated amorphous, while composition morphol...

Grain boundary segregation of boron in nickel has been investigated using secondary ion mass spectrometry and FIM-AP techniques. Preliminary results show that segregation is of the equilibrium type which means that boron was concentrated to a few atomic layers at the grain boundaries and that the amount of segregation increased with decreasing annealing temperature.

Grevillea exul var exul (Proteaceae), a tree species native to serpentine soils in New Caledonia, is a reported manganese accumulator. Since the metal tolerance of this species remains unknown, its growth and metal accumulation were studied for seven heavy metals under controlled conditions. Brassica juncea, a popular species for metal phytoremediation, was used as a reference. G. exul seedling...
