Topic: The Correlation Between Corrosion and the Future of Medical Healthy Implants


Affiliation: Director Corrosion Research Center Nano-Bio & Advanced Materials (SCE), Israel 
Vice Chair AMPP Board of Directors


Abstract: Today there is an increasing demand for healthy long- and short-term medical implants. 
Within the last years regulatory approval became more difficult for medical implants. For example once taking into account ISO 10093 the implant surface is a key role to the overall obtained results. 
One of the major considerations today is to define the design and engineering requirements in parallel with the overall parameters and surface repair. Bio function surface behavior should include surface engineering and surface control efforts comprised of policies, processes and procedures that address corrosion across the complete lifecycle of the implant, from design to decommissioning. Biodegradable implants should aim for establishing a reliable in-vitro/in-vivo correlation of the corrosion degradation based on the bio-active mechanism which is still a major challenge to achieve. 
This presentation will discuss, materials selections and surface prevention systems such as coatings. The presented applications will focus on the importance of applied bio function surfaces for biomaterials applications as well as on the biocompatibility requirements under stimulation of real time conditions.  
Overall, the lecture will also focus on the relationship between long-term implants such as titanium alloys and short-term implants such as magnesium alloys

Topic: Challenges in the Cathodic Protection of Concrete Structures


Affiliation: Business Development Manager 
Vector Corrosion Technologies Ltd.


Abstract: Corrosion of reinforcing steel leading to structural deterioration and failure of reinforced concrete structures is a serious problem for asset owners.  
Impressed current cathodic protection for atmospherically exposed concrete structure was first used in a concrete bridge deck in 1974, and galvanic anodes for concrete structure was first used in 1990s. There have been many successful concrete structure projects that has employed cathodic protection, while these successes have come with many challenges. 
This presentation will first briefly introduce the developments and types of cathodic protection systems, then discuss challenges and lessons learned, and finally present case studies.

Topic: New Generation Steels and Materials with Superior Corrosion Resistance


Affiliation: Vice President Technology & New Materials Business, Tata Steel Limited


Abstract: Steels are generally considered as more environment friendly than other materials because of the high degree of recyclability. Variety of new generation steels such as super duplex stainless steel, high nitrogen steels, Corten steel etc., have been developed with superior corrosion resistance property and these are extensively used in different applications in structural, railways, power and energy sectors.  
 
Variety of coatings have also been developed to improve corrosion resistance of plane carbon steels. Global trend is shifting from conventional zinc coatings to Zn/Al based alloy coatings, i.e., addition of ternary, quaternary and even quinary alloying elements to impart enhanced sacrificial and barrier corrosion properties. These coatings can offer excellent corrosion protection owing to the complex microstructural features and their stable corrosion products. Composite coatings are also a major focus of development as they offer additional functionalities for new application areas, especially in construction sector. Innovative processing techniques such as physical vapor deposition, chemical vapour deposition and amorphous coating have also been developed to achieve superior corrosion resistance.   
 
New generation structural materials such as polymer matrix composites have inherent corrosion resistance because of the polymeric matrix. Together with reinforcement with glass, carbon, aramid or other fibres, the polymer matrix composites provide useful combination of strength and corrosion resistance. The density of these composite materials is 1/3rd to 1/6th that of steel. Thus, these new materials offer unique combination of properties that will make them suitable for many applications where concrete, steel or aluminium are used today. The internal panels and components of railway passenger coaches are already transforming to composites. In water carrying pipes, pressure vessels for water filtration, chemical tanks and pipes, composites are already favoured materials. The world will see progressive increase in use of polymer matrix composite materials. 
 
Graphene has many unique properties. Graphene nano-platelets in an appropriate suspension, can be used as paint. The graphene platelets have high resistivity across thickness and make the path of electrons tortuous around the platelet boundaries. This results high barrier resistance to corrosion. Graphene based paints, applied to steel structures, provide twice to three time more corrosion resistance than normal paints used for such purposes.
