Date: 24 Apr 2013 - 24 Apr 2013

Venue: SIMTech Auditorium, Tower Block, Level 3

Seminar on Advanced Coatings for Corrosion and Wear

The seminar on Advanced Coatings for Corrosion and Wear will take place on Wednesday 24 March 2013  from 12:30pm to 6pm at the Singapore Institute of Manufacturing Technology (SIMTech), a research institute of the Agency for Science, Technology and Research (A*STAR).

Introduction
Annual corrosion costs in Singapore amount to more than 4% of GDP. Due to its widespread occurrence, corrosion affects most industrial sectors. Thus, good understanding of the nature of corrosion together with proper protection and maintenance practices is imperative to save a significant percentage of corrosion costs. Reliable testing and performance evaluation are crucial, including field testing and laboratory acceleration tests. Similarly, the application of appropriate coatings is essential for optimum corrosion protection. Another related area of protecting metals is the application of wear resistant hard coatings to prevent or delay surface damage due to contacting moving parts or due to external factors such as erosion, scratching, or abrasion. The seminar aims to address issues of corrosion testing, and application of coatings for corrosion protection and wear resistance.

Focus areas will be:

- Corrosion and wear problems in industries
- Corrosion testing and investigation facilities, and training programmes
- Coatings technologies for corrosion and wear protection

The seminar will also showcase an exhibition with industry participation featuring various products and applications.

Key trends, new developments as well as established capabilities will be presented and discussed in the Seminar. These will not only benefit participant's product development process and productivity but also provide deeper insight on corrosion and wear problems and relevant protection methods.

SIMTech undertakes various initiatives to help local industry in the area of corrosion and wear protection.  These include a series of training courses (funded and certified by WDA) as well as planned Collaborative Industry Projects on corrosion testing, and corrosion and wear protection to be launched in 2013. The Seminar will provide the opportunity to hear from participants and collect invaluable feedback for SIMTech upon which the upcoming project scopes will be defined.

SIMTech has excellent facilities and researchers covering coating technologies which can be used for corrosion prevention and wear protection. These technologies include corrosion testing methodologies, sol-gel based protective coatings, physical vapour deposition (PVD) coatings, chemical conversion coatings, and electroless nickel coatings. Of these, corrosion testing methodologies, sol-gel coatings and PVD coatings will be highlighted in the Seminar.

SIMTech has also developed PVD thin film coatings ranging from conventional to advanced super hard and super tough nanocomposite coatings for wear protection. In particular, the nanocomposite has successfully been deployed on components and tools used in the PE industry realised noticeable service life extension. From which the reduction in equipment down time translates into costs saving, i.e. reduction in frequent stoppages for tools change, hence productivity improvement.

He has spent several years at BP Research, researching into erosion and corrosion resistant coatings and returned to Southampton in 1993 to re-establish surface engineering/tribology research. He is the director of the National Centre for Advanced Tribology, nCATS.

Professor Wood has research interests in rain, cavitation and solid particle erosion, erosion-corrosion interactions and modelling; tribological and multifunctional coating design and performance, biomimetic coatings for anti-fouling; electrochemical control of interfacial friction; particle modelling in pipe bends by swirl dispersion of particles.

Abstract
This talk will look at certain aspects of offshore and marine related tribocorrosion of components affected by combined wear-corrosion interactions. The variety of possible interactions between mechanical and corrosion processes and materials/coatings will be discussed based on real service situations. It will also explore whether we need to compromise between high wear and high corrosion resistance to obtain good tribocorrosion resistance. Cases where resistance against third body (abrasives/erodents) induced wear-corrosion is important as well as sliding wear-corrosion are presented.  Examples will be used such as pump impellers, drilling equipment, propellers and valve inserts and will include erosion-corrosion, abrasion-corrosion and sliding wear-corrosion of marine and offshore materials and coated systems.

Dr Juergen Walter completed his PhD at the University of Ulm, Germany. He has over 15 years' experience in industrial coatings covering areas like concrete protection and functional PTFE coating solution. He joined Whitford Pte Ltd in Singapore in 2007 as a Regional Technical Manager responsible for the Asia Pacific region.

Abstract
Corrosion has been the number one issue over the years for fasteners, bolts and nuts. Traditional methods to protect the metal surface like galvanizing have been failing in areas where long term corrosion resistance and exposure to harsh environmental conditions is required. The presentation will cover some of the solutions Whitford has been providing to the industry, not only to improve corrosion resistance but adding additional values like torque control.

Dr Sandor Nemeth earned his PhD at Syracuse University, USA. After post-doctoral positions at Texaco R&D Department, Ethyl Petroleum Additives Inc., and Virginia Commonwealth University he joined PSB in Singapore and participated in the testing and development of polymer related materials and coatings. Dr Nemeth started working in SIMTech in 2001, focusing on the development of functional coatings, especially sol-gel coatings with corrosion protective function as well as abrasion and scratch resistance.

Abstract
Corrosion protective coatings often rely on epoxy or polyurethane binders which can provide good performance. However, such coatings may require high dry film thickness of hundreds of micrometres. Alternative coating technology shall be presented based on sol-gel coatings that are capable of providing excellent corrosion protection even in relatively thin layers of about 50 microns on steel and 10 microns on aluminium. Using thin coating layers can save substantial coating material. In addition, sol-gel coatings have excellent abrasion and scratch resistance that will be described briefly.

Abstract
Corrosion can cause dangerous and expensive damage and there is estimation that it costs Singapore more than 3% of GDP. Driven by fundamental natural forces, corrosion is related to all the industrial sectors. A good understanding of the mechanisms of corrosion together with proper prevention and maintenance practices is imperative to save a significant percentage of maintenance costs.  Reliable testing and performance evaluation, including field testing and laboratory acceleration tests, are crucial for establishing such understanding and practices. It is also essential to eliminate the malpractices about corrosion testing which could lead to erroneous conclusions. The objective of this presentation is to highlight the vital corrosion testing and characterisation practices needed for manufacturing sector based on atmospheric exposure tests, accelerated laboratory (chamber) tests and electrochemical tests.
