Abstract:
Electroless deposit Ni–P/SiO2 composite coating was performed on the steel substrate, DIN EN 10130. The preparation of nickel coating included two main steps. In the first step, the fraction of SiO2 particles sized the tens of nanometres was obtained by sedimentation. In the second step, the composite coating was plated on the steel substrate. The actual deposition process contains the deposition of plain Ni-P interlayer which served as the nucleation center for the deposition of Ni-P/SiO2 composite coating with co-deposited SiO2 particles. The morphology of deposited composite coating was stu

The catalysts that can efficiently hydro-reform higher n-paraffin to lower isoparaffins for environmentally friendly gasoline were studied. The catalysts were examined by the conversion of n-hexadecane, n-C16H34 to i-C6H14~i-C12H26. The tri-modally nanoporous (nanometer-size) catalysts composed of (Ni-Mo)/[γ-Al2O3], nano-oxide, and nanocrystalline zeolite have some active and selective performances because of the cooperation between (Ni-Mo)/[γ-Al2O3] and the composite of nano-oxide-nanozeolite.

The Cu-based friction material with Ni coated nanometer SiO2 (Ni/n-SiO2) particles was prepared by the powder metallurgy technology. Friction properties of the friction materials were evaluated by a friction tester. The microstructure and worn morphology were characterized by optical microscope (OM) and scanning electric microscope (SEM). The results indicate that the microstructure is uniform. The Ni/n-SiO2 particles can enhance the wear ability of Cu-based friction materials. The wear rate of the friction material with Ni/n-SiO2 is 6.58 times of that without Ni/n-SiO2.

Abstract:
Mo-Si-based superalloys are of interest as a new family of high-temperature materials to replace Ni-based alloys. By means of in situ environmental transmission electron microscope, the transient period of the early oxidation of Mo3Si was investigated at the nanometer scale. As a result of a competition between loss of volatile MoO3 and association of SiO2 molecular units into pillars, a nanometer-sized porous SiO2 grows at a very initial stage of the oxidation of Mo3Si.

Abstract Reactive thermal spraying, in which thermodynamically stable compounds are formed by expected in-process reactions, has attracted considerable attention as a result of wide availability to in-situ composite coatings. Such inprocess reactions differently proceed in HVOF and plasma spraying because of differences in the flame temperature and speed. In the present study, composite powder of SiO2/Ni/Al-Si-Mg was deposited onto an aluminium substrate to fabricate in-situ composite coatings by both spraying methods.
