Long-term use of indwelling medical catheters has often been hindered by catheter-associated nosocomial infections. In this study the effectiveness of silver coating of polystyrene and polyethylene polymers was investigated. Polymer pieces of 2 cm(2) each were coated with a thin layer of silver using electroless plating technique. Silver-coated polymers were challenged with cultures of four dif...

Mussel-inspired polydopamine (PDA) chemistry and electroless deposition approaches were used to prepare stable superhydrophobic coatings on wood surfaces. The as-formed PDA coating on a wood surface exhibited a hierarchical micro/nano roughness structure, and functioned as an “adhesive layer” between the substrate and a metallic film by the metal chelating ability of the catechol moieties on PD...

A novel technique for obtaining nonanomalous Ni-Zn-P coatings with high Ni content ~74 wt % as compared to 15-20 wt % in the conventional plating method! has been developed. These coatings show promise as a replacement for Cd in sacrificially protecting steel. Ni-Zn-P coatings were deposited using an electroless method from a solution containing NiSO4 , complexing agent and ammonium chloride. V...

Magnesium-based bulk metallic glass matrix composites (BMGMCs) have better plasticity than the corresponding bulk metallic glasses (BMGs); however, their strength and density are often compromised due to the fact that the effective reinforcement phase is mostly plastic heavy metal. For lightweight SiC-particle reinforced BMGMCs, interface wettability and the sharpness of the particles often red...

lectroless nickel plating is a relaE. hvely new technological process. The first laboratory experiments were done in 1944 by A. Brenner and G. Riddelll during World War 11. Public announcements were made a few years later. This work bad been done without knowledge of the earlier observations by Roux in 1916* and by Wurtz3 in 1845. The early work was not successful due to poor quality reagents a...

Electroless nickel composite coatings have the potential for high-temperature tribological applications, and a combination of high wear resistance low friction factor is one desirable solutions but still tricky problem. The addition self-lubricating WS2 hard Si3N4 nanoparticles to Ni-P expected obtain good performance. In this work, Ni-P-Si3N4-WS2 with various contents were prepared using elect...

The addition of magnesium to Aluminum alloys has become increasingly popular due their lightweight, high strength, and corrosion resistance properties. Our research on high-content Mg doped 90, Al-10 wt% alloy shown that coating it with electroless Ni-P codepositing nano-Al2O3 (0, 2.5, 5 7.5 wt%) can significantly improve its mechanical properties, wear & tear, even resistance. Ni-P-5 Al2O3...
