In this work the effects of various methods of agitation on the properties of electroless Ni-P-MoS2 composite coatings were investigated. Magnetic stirring as well as purging the solution with gas (Air, Oxygen, Nitrogen) were used. Plating rate, chemical composition, MoS2 distribution, and hardness of the deposit were measured. Topography of coating was studied with metallography and scanning e...

The lifespan of low-carbon steel petroleum pipelines can often be shortened by the erosion–corrosion damage caused their service conditions. Applying electroless Ni-P coating is a promising option to protect from environment due its high hardness and corrosion resistance. However, has low toughness but increased addition NiTi ductile particles. This work produced Ni-P-NiTi coatings different th...

Carbon nanoparticles have excellent lubricating properties, however, they are less involved in metal protection. In this study, easily prepared candle soot was added to electroless nickel-phosphorus plating as a re-enforcement particle. Ball-disc friction and wear tests were conducted evaluate the wear-resistance capabilities of Ni-P coating Ni-P-CS (Candle Soot) composite coatings. The paramet...

In this talk, we report a research work on fabrication and metallization of high aspect ratio polymer microstructures fabricated using UV lithography of SU-8 on silicon substrate. Electroless plating of metal film on both the top and sidewall surfaces of microstructures were achieved while the silicon substrate was not plated. The primary chemical mechanisms and possible applications were also ...
