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

In order to improve the high-temperature behaviors of hot work die steel in engineering application, the high-temperature wear and thermal fatigue behavior of brush plating Ni/nano-SiO 2 composite coating have been investigated. The microstructure of Ni/nano-SiO 2 composite coating has been analyzed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). TEM observation of Ni/nano-SiO 2 composite coating has shown that the added SiO 2 particle with an average size of about 20 nm is uniformly distributed in Nickel matrix.

A Pd-Ni/La(Sr)CrO3-Ce(Sm)O2 composite anode showed good performance for solid oxide fuel cell reactions with dry CH4. Compositions of Pd and Ni in the Pd-Ni/La(Sr)CrO3-Ce(Sm)O2 composite anode affected the electrochemical oxidation catalysis of dry CH4. The Pd and Ni ratios from 50:50 to 75:25 were suitable for the oxidation. The Pd-Ni/La(Sr)CrO3-Ce(Sm)O2 composite anode showed the high tolerance to the carbon deposition under closed and open circuit conditions. A Pd-Ni/Ce(Sm)O2 catalyst showed very low catalytic activity for decomposition of dry CH4. A Pd-Ni/SiO2 catalyst showed very high cat

Also, the crystallization of the films and the crystal particles increase effectively due to addition of nano-SiO2. Hence, the thermal stabilization and elastic modulus of the films ca
