Microalgae and other microorganisms play a significant role in the transport of heavy metal ions in the environment while at the same time they are closely related to the formation...

...Abstract This paper will deal with zinc coated ductile iron pipe - its history and development, manufacture, and performance against corrosion. Test results from the Everglades will be presented showing various specimen combinations with emphasis on zinc coated ductile iron pipe with and without...

...Zinc can also be corroded by proton when the zinc surface’s passive film is damaged by SRB. At pH 7, 2H⁺/H₂ potential (E^o' = −414 mV) is not much higher than that for Fe²⁺/Fe (E^o' = −447 mV), making proton attack of carbon...

... are not applicable for galvanized steel rebars because the zinc and the steel form a galvanic couple and the value of the open circuit potential is a function of the exposed area ratio of the zinc and the steel. In order to verify and suggest a classification similar to that of the carbon steel rebars for galvanized...

... of concrete protective coatings and cathodic protection techniques. In this context, dual-coated (zinc/epoxy) rebars have been widely used in various countries with very promising results. In Brazil, the use of coated rebars is incipient, summarized in some use of galvanized bars in special concrete...

...Abstract Thermal spraying of zinc and zinc alloys is a well-established process which is used for long-time corrosion protection of steel structures in maritime surrounding conditions and for offshore structures since decades. The paper summarizes the actual arguments to use long-time cathodic...

... potential decreases the risk of hydrogen embrittlement. Zinc-based alloys have been among the most evaluated galvanic materials for concrete structures, especially in USA, in many applications: thermal spray, superficial metal/mesh with and without hydrogel adhesive, embedded in concrete (point anodes...

...Brass is defined as “an alloy consisting mainly of copper (>50%) and zinc, to which smaller amounts of other elements may be added” ¹ . Brass is an important industrial alloy valued for its thermal and electrical conductivity, corrosion resistance, strength, and ductility. Brasses...

... For the purposes of this paper nano-laminated coatings are zinc-based metallic alloy systems applied electrochemically, at room temperature, to steel substrates to enhance corrosion resistance and base material mechanical properties. The unique metal attributes achieved by nanolamination impart not only improved...

... that were investigated for use on steel structures, components, and ground support equipment in order to provide corrosion protection and reduce VOCs and hazardous waste. In this investigation, low VOC coating systems were applied over zinc TSC primers and evaluated for compatibility with zinc TSC...

... by a thin layer of zinc with a thickness of 20-80 μm. The corrosion of galvanized steel in soil consists of three stages. In the first stage of corrosion, the zinc layer dissolves into soil pore solution. When the underlying steel is exposed to the soil environment in the second stage of corrosion...

... in groundwater simulating repository conditions has been studied continuously since 1998. The aim of these studies is to get a reliable data for the dissolution of carbon steel in repository conditions. On the grounds of the results the long term corrosion behavior of activated carbon steel and zinc containing...

...Abstract The stainless steel tanks of a zinc hydrometallurgy plant have experienced stress corrosion cracking (SCC) since they were built 20 years ago. The diluted sulphuric acid solution with 300 ppm chloride ions is known to be particularly aggressive. In order to reduce the susceptibility...

Concrete Concrete Patch Repair Corrosion Reinforcing Steel Zinc INTRODUCTION Zinc anodes are known to passivate in an alkaline environment, much in the same manner as reinforcing steel, and this passivation will impede the flow of galvanic current. It is therefore necessary to activate the zinc...
