optimization of preliminary treatment on the surface of boron nitride particles for ni-p electroless coating
applying a ni-p electroless coat on the surface of bn(h) particles has a beneficial effect on their wettability in vortex technique during composite manufacturing. in this investigation, different preliminary treatments consisting of different combinations of surface oxidation, sensitization and activation have been investigated. the results obtained from scanning electron microscope (sem) and ...

This review outlines the development of electroless Ni–P composite coatings. It highlights the method of formation, mechanism of particle incorporation, factors influencing particle incorporation, effect of particle incorporation on the structure, hardness, friction, wear and abrasion resistance, corrosion resistance, high temperature oxidation resistance of electroless Ni–P composite coatings ...
متن کاملNi-B Coating Production on Magnesium Alloy by Electroless Deposition
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...
متن کاملFabrication and Characterization of Nanostructure Functionally Graded Ni-P Electroless Coating
In this research, novel functionally graded Ni-P coating was deposited with electroless process. The content of phosphorus was controlled to change gradual through the thickness of the coating. During the plating, bath temperature and pH were changed at specified intervals to obtain functionally graded structure. To compare the properties of functionally graded coating with Ni-P single-layer co...
متن کاملCorrosion Behaviour of High-Mn TWIP Steels with Electroless Ni-P Coating
An attempt has been taken to improve the corrosion resistance of twinning-induced plasticity (TWIP) steels (Fe-25Mn and Fe-25Mn-3Al) by electroless Ni-P coating. Corrosion resistance in 3.5% NaCl and 0.1M H2SO4 solutions was characterized by the potentiodynamic polarization curves and Tafel method calculations. It was found that Ni-P coating improved the corrosion resistance by the factor of 4 ...
