“…The microstructures presented in Figure 4b and 5 demonstrate that ultra‐fast diffusion paths are very efficient in re‐distributing lead during recrystallization annealing, a feature that can be utilized in the design of composite materials releasing certain components during service. Upon heating, GB wetting may also facilitate the propagation of lead along grain boundaries with subsequent precipitation to fine particles at GBs as the temperature decreases 25, 26, 27…”

Severe plastic deformation of pure Cu and Cu‐rich alloys was found to create a hierarchical combination of fast and ultra‐fast diffusion paths ranging from non‐equilibrium grain boundaries to non‐equilibrium triple junctions, vacancy clusters, nano‐ and micro‐pores, and finally to general high‐angle grain boundaries. Under certain conditions, a percolating network of porosity can be introduced in the ultra‐fine grained materials by a proper mechanical and thermal treatment. This network may offer promising opportunities for creating materials with tailor‐made properties, including combinations of improved mechanical performance with a possibility of self repair using “vascular structures” for atom transport. Applications in such areas as drug eluting bioimplants and lead or polymer eluting materials for reduction of friction based on impregnation of porosity networks with these agents are also envisaged.

“…Two modes of interaction have been proposed to explain this outstanding inhibition efficiency. The first postulates the formation of Cu(I)BTA polymeric film (1)(2)(3)(4)(5) while the other one suggests the formation of an adsorbed layer of BTA on the Cu Surface (6)(7)(8)(9)(10)(11)(12) . This work is planned to use a simple technique which is partially covering C-steel surface with Cu nanoparticles (NPs) then immerse them in benzotriazole (BTA) to decide which of the adsorption and the film formation mechanism is responsible for the high corrosion inhibition efficiency (IE) of BTA for Cu and its alloys.…”

Corrosion Inhibition of C-Steel Using Supported and Non-Supported Cu-Nanoparticles/Benzotriazole

Depositing Cu nanoparticles on the C-steel surface using the self-replacement technique has shown corrosion inhibition efficiency higher than 91% in acidic medium if the Fe/Cu system was preimmersed in 1 mM benzotriazole for 15 minutes. The use of polyaniline nanotubes as a support for the Cu nanoparticles did not enhance the inhibition efficiency of Cu nanoparticles for Fe. On the contrary, it decreased a little bit. This work compares between corrosion inhibition efficiency of the polyaniline nanotubes and Cu nanoparticles separately and in presence and absence of benzotriazole. In addition, this work introduces a new and simple technique that is able to decide how the benzotriazole molecules interact with the Cu surface. It was proven using this technique that at the free corrosion potential, the interaction takes place mainly through the adsorption mechanism rather than the Cu(I)BTA film formation one.
