Recent Patents on Corrosion Science - Volume 2, Issue 1, 2012

Recent Patents on Corrosion Science was launched in June 2011 and now we are publishing 2nd volume of the Journal. This Journal publishes review and research articles and guest edited thematic issues on recent patents in the field of Corrosion Science. In this issue seven papers have been included. The first paper entitled “Techniques for In Situ Corrosion Studies of 316L Stainless Steel in Sulfuric Acid Solutions” is written by Read More

An in situ optical microscopy and simultaneous electrochemical analysis method is presented for studying 316L stainless steel in sulfuric acid based solutions. The electrochemical methods involved potentiostatic and potentiodynamic analysis of 316L stainless steel surface in aerated and deaerated 1M-3.39M H2SO4 while varying Ni+ and Cl-. This technique is reviewed along with several other in situ surface analytical prob Read More

This review presents a selection of patents reported on coatings for high-voltage porcelain insulators. An insulator is subject to surface corrosion due to air pollution or salt deposition, which may form a conductive electrolytic solution. This may cause a flashover and shut down the transmission and distribution electrical energy line, particularly in high polluted or coastal regions. The main goal of protective coatings Read More

Corrosion played a significant role in the catastrophic collapse of many aged steel bridge infrastructures around the world. Those damages and many reviewed patents intensified the importance of careful evaluation of existing structures for the feasibility of current usage and strengthening them by retrofitting some selected corroded members to ensure the public safety. Only experimental approach is not enough to estimat Read More

The methanol electro-oxidation in alkaline solution was studied on titanium electrode carrying Ni-P and Ni deposits. The phosphorus in Ni-P makes the Ni-P deposits fine and fine, and leads to the Ni-P deposits with a high specific surface area. Meanwhile, the weak binding between hydrogen and the Ni-P makes adsorbed hydrogen from methanol dehydrogenation on Ni-P deposits more easily cleaned up and makes Ni-P deposits to Read More

In situ phosphatizing coating (ISPC) was invented and patented in 1994, where in situ phosphatizing reagent (ISPR) was shown to form a dense interfacial phosphate layer on and bond strongly with metal substrates, and simultaneously link with covalent bonds to the polymer top-layer. In this paper, we report the synthesis of ISPR-catalyzed polysilsesquioxane (PSSQ) oligomers by the sol-gel method. Using different amounts of Read More

Flow Accelerated Corrosion (FAC), also known as Erosion-Corrosion (EC), is a serious safety and reliability problem facing carbon-steel pipes in power generation plants. It is also a serious problem in the oil and gas industry when oil, gas and solids flow together through piping systems. This phenomenon results in wear and thinning of large areas of pipes and fittings which could compromise their structural integrity and there Read More

The application of thermally sprayed ceramic or metallic coatings has become an important part of surface coating technology. Over the last two decades, the industry has seen extensive development of sophisticated equipment that has simplified the application of thermal spray coating to complex surfaces. The availability of a broad range of tailored feedstock materials, and sensitive characterization and quality assurance Read More

The patents annotated in this section have been selected from various patent databases. These recent patents are relevant to the articles published in this journal issue, categorized by the processes and technologies related to various disciplines of corrosion science.
