Abstract: The FFC-Cambridge process is a generic molten salt electrolytic method that was invented at the Department of Materials Science and Metallurgy of the University of Cambridge more than one decade ago. This process is commonly used for the direct conversion of metal oxides into the corresponding metals and alloys through the cathodic polarisation of the oxide in a molten salt electrolyte based on calcium chloride, and a range of academically and commercially interesting materials have been made in this way in the past. However, beyond this, the FFC concept may also be applied to preclude the ingress of oxygen into metal substrates while processed under extreme experimental conditions. 
In the present study, laser beam melting of titanium alloy Ti-6Al-4V was performed with an Yb-fibre laser to produce weld pools under a range of conditions. These included the use of a flux covering of molten calcium fluoride or a molten mixture of calcium fluoride and sodium fluoride, in an atmosphere of ambient air, either with or without the application of cathodic protection to the Ti-6Al-4V. In the absence of flux, considerable oxidation of the metal occurred. In contrast, in the presence of flux, the degree of oxidation was greatly reduced. In addition, the application of a modest cathodic potential to the flux-covered metal reduced the pick-up of oxygen even further. The results suggest that the use of an appropriate flux combined with cathodic protection when fusion welding titanium and its alloys may offer advantages in circumstances where inert gas shielding is not always feasible, for example, in certain site welding applications.

Paper Title: “Offshore Structure Life Extension Using Low-Cost Diver-less Cathodic Protection Retrofit Systems”

Affiliation: Vice President & General Manager of Galvotec Corrosion Services, Associated with IEV Engineering (India) Pvt. Ltd.

Abstract: One of the major expenses in any offshore structure anode replacement system has been the high diving and/ or ROV costs, along with the costs of their support vessels. If these expenditures can be eliminated, the overall price of an installed cathodic protection system can be greatly reduced. For structures in depths up to 75 meters a diver-less installed galvanic Aluminium anode system has seen great acceptance. This system will be discussed along with examples of these installations. For structures with AC power available and that have a high current requirements, a diver-less installed impressed current system that has been used on structures in depths to 125 meters will be discussed. Both of these systems have proven track records of use and have become common retrofit techniques in the Gulf of Mexico and can be installed worldwide.

Biography : Upon graduation from college in 1972 Mr. Johnson was employed in the offshore anode retrofit industry and worked may years with the company that introduced aluminium anodes to the offshore old industry. He was involved in the development and installation of many of the earliest retrofit aluminium anode systems developing a number of the standard installation systems and techniques used today on offshore structures. He project managed many diving installations over his career and even was the division manager for Cathodic Protection for another major international diving company. He was the first to author a paper on the design of anode core shapes for offshore aluminium anodes after discovering design defects in the early types of core materials used in aluminium anodes. He has worked on the development of impressed current systems for offshore use and has developed installation techniques that require less installation time and cost than systems requiring diving or ROV intervention. In 2018 Mr. Johnson has been recognized for his 45 year membership in NACE. He has held numerous volunteer positions within NACE and is a Past USA Central Area Chairman. Presently he is the Chairman of a NACE Technical Committee writing a State of Art Report entitled: “Retrofit of Cathodic Protection Systems for Fixed Offshore Platforms”. For the past 21 year Mr. Johnson has been the Vice President and General Manager of Galvotec Corrosion Services based in New Orleans, Louisiana and have been involved in the production and installation of offshore cathodic protection systems of both galvanic aluminium anodes as well as the exclusive distributor for the Lockheed Martin developed Vertical Tension Anode system.

Abstract: Biofouling refers to adhesion of micro-and macro-organisms on metal substrates leading to biofilm formation. Microbially-influenced corrosion (MIC) on metals and alloys is a consequence of such biofilm formation and many strategic industries such as nuclear power, oil and gas production and transport, marine vessels and structures are significantly affected. In this lecture microbiological and physicochemical aspects of biofouling and MIC are illustrated with examples. Mechanisms in MIC of steels under different industrial conditions are detailed. MIC-causing microorganisms such as sulphur and iron oxidizing bacteria and Sulfate Reducing Bacteria (SRB) are illustrated. Methods of failure analysis and prevention methods are brought out.

Paper Title: Role of cations on wet corrosion behaviour of metals

Affiliation: Assoc. Prof., Dr. of Eng., 
Faculty of Engineering, Hokkaiod University

Abstract: Corrosion of structural metals in aqueous environments such as sea and fresh water is serious problems for safe usage of infrastructures. It is well known that the corrosion behaviour of metals depends on the environmental factors, such as, concentration of chloride ions, temperature and pH. The effect of metal cations on corrosion behaviour of metals in aqueous environments has not pay much attention until recently. There are reports [Surface and Interface Analysis; 45 (2013) 1517, Electrochim Acta; 131 (2014) 123] that corrosion behaviour of metals such as steels and aluminium alloy in aqueous environments is also affected by metal cations, which are contained in the environments as minor elements. Some of the metal cations could also enhanced corrosion resistance ability of adsorption type corrosion inhibitor [Corrosion Review, 36 (2018) 105]. 
The mechanism of metal cationic effect on corrosion behaviour of metals is not fully elucidated, however, some of the metal cation may form a layer composed of oxide or hydroxide of metal cation on passive film of steels and aluminium alloys. Based on the layer formation, Otani et al. [Corrosion Science; 111 (2016) 302] reported that the effect of metal cations in the environment can be described by corrosion inhibitory effect of cation, Y, which is calculated by X ×?V-1. Where X is metal cation hardness that is an indicator based on the Hard and Soft Acids and Bases concept, and ?V is difference between molar volume of metal cation compound and molar volume of passive film of metal.  
In this Keynote talk, recent results regarding role of cations on wet corrosion behaviour of aluminium alloy and steels will be introduced.

Abstract: The technology was restricted to applications enabling functions like CAD, Analysis, Project Controls and recently ERP. Some industries adopted them early on and many still are lagging. But technology did not stop re-inventing owing to lower costs and quicker commercial adoption. Sectors like retail and banking were quick to adopt owing to their business model and customer expectation. Mobile technology helped in customers of these sectors too adapting to products like net-banking, mobile-wallets. It was a win-win situation for all. 
Herein lies the difference in EPC, which forms an important topic of CORCON. EPC sector is prone to cut costs and keep technology to bare minimum. Most of it is due to culture, availability of low cost resources, IT not a main enabler for business functions. This has changed and changed for good. Softwares are going the enterprise way. Digital natives are forming part of the workforce. Customers are expecting much more from less. There is no option but to transform the way we work using technology to a much larger scale than we ever imagined. Advent of digital cutting edge technologies are forcing companies to think how they should plan for the next decade. This presentation will cover topics of technologies that customers are adopting, some case studies and capabilities of a typical EPC company to address such implementation.
