zinc-nickel electrodeposits have been widely adopted for surface treatment of automobile steel sheet for high corrosion resistance. in this work the effect of pulse parameters on the zn-ni alloy electrodeposits was investigated. the hardness, thickness, corrosion resistance and composition of deposits thus produced were investigated. the surface topography of the deposits was also observed in s...

Background: Distal tibia fractures are among the most common bony injuries, with a significant rate of nonunion anddelayed union. There are multiple methods for the management of distal tibia fractures. Among the plating methods,there are bridge plating and compression plating techniques. There is still a lack of evidence about whether one methodhas a higher rate of union than...

This paper focused on a novel method of electroless plating ruthenium (Ru) on solid or porous substrates like porous stainless steel (PSS) discs or ceramic tubes. A novel complexing plating bath of Ru was developed. It is proven that Ru can be deposited directly on these substrates by the bath at a temperature of 328 K and strong alkaline environment. TGA, SEM, EDX and XRD confirmed the success...

background: the entrance of toxic compounds into wastewater treatment plants (wwtps) can induce disorder in their biological units. therefore, it is necessary to determine the sources of toxic wastewaters. in this study, the toxicity of the wastewater of 3 metal plating industries was assessed using sequencing batch reactor (sbr) bacteria. methods: to obtain the 1-1000 ml/l concentrations, the ...

Electroless nickel plating is a widely used plating method in many industries. The usability of the coating is, however, restricted by the control problems related to the electroless nickel plating process. To ensure deposit quality, the transcendent properties of electroless nickel deposit should be accurately controlled during plating, which is challenging because of the spontaneous, unstable...

Colony counting by spreading bacterial suspensions on plating media by various techniques is of general concern. Comparative studies between hand plating (Drigalski-spatula technique) for different time intervals and spiral plating resulted in significant differences in colony counts. Lower counts of Gram-negative bacteria were obtained by using hand plating for more than 10s, compared with sho...

background:  there is still controversy regarding the best technique for ankle arthrodesis to acheive stable rigid fixation along with reconstructing a functional plantigrade foot. moreover, existing techniques have complictions related to stability, soft tissue covering, fusion rate, and exposure. methods: with the anterior approach exactly on the tibialis anterior sheath, the joint was expose...
