Corrosion is a surface phenomenon and surface engineering plays important role
in corrosion prevention and mitigation by optimizing surface properties.
Coatings, surface alloying, gradient structures, inhibitors are some of the
examples of improving corrosion performance by controlling surface properties.
Focus of the symposium is to capture recent advancements in surface engineering
for corrosion prevention. New technologies to 1) study the corrosion phenomenon
of surfaces and 2) induce novel surfaces properties are of particular
interest. The symposium topics include but not limited to:
- Coatings
- Inhibitors
- Surface Alloying
- SMAT
- Laser, plasma, mechanical processing of the surfaces
- Nanostructured surfaces
- Characterization techniques
- Biomaterials
- High temperature coatings
Most of the processes of materials engineering involves surfaces and interfaces
which determine the evolution of the process/materials characteristics, and in
many cases define the end properties of the materials. Understanding and
developing strategies to control surface interaction have been the subject of
research for centuries. In non-biological materials, some of the well known
phenomena where surface/interfaces are important include phase transformations,
ripening, repulsion/attraction of particles by liquid or solid interfaces,
lubrication, friction, wear, corrosion, and many others. In biology and human
health areas, surface interactions occur in processes such as phagocytosis,
adsorption of chemicals by cells and microorganisms, cell multiplication (cell
fission, mitosis and meiosis) which are part of natural processes or induced
that could be beneficial or detrimental. These interface interactions may be
part of different stages of more complex ones, such as osseointegration,
hemocompatibility and other tissue compatibility, which are key aspects for
implantation of devices in human and tissue engineering. In addition,
nanotechnology presents new challenges for the comprehension of surface
interactions due to high surface area to bulk ratio. Moreover, nanostructured
materials in particulate, rod, plate or nanotube configurations adsorb and
adhere chemical compounds which can give improved or specific properties for
the development of new technology. The present symposium seeks to capture
scientific advancements in understanding surface/interface phenomenon,
controlling surface/interface characteristics in introducing novel properties,
and technologies to characterize interfaces. Interface phenomenon in
nanostructured materials, biomaterials, metals and alloys, advanced coatings,
composites, wear and corrosion, environmental degradation, energy generating
systems are of particular interest.
As technologies advance, the durability limits of materials are being tested
and the development of advanced surfaces meeting new challenges is required.
Existing processing approaches are being adopted and new processes are
constantly emerging to generate novel surfaces. The past few decades have
witnessed significant research attention on nanostructured materials and their
applications in various fields including surface engineering. Nanostructured
materials have demonstrated significantly improved functional properties
including corrosion and wear resistance. New applications are being sought for
the nanostructured surfaces. Various technologies for the preparation of
nanostructured surfaces exhibiting desired properties have been developed.
Characterization, evaluation of properties at multiple scales, and
understanding the unique behavior of nanostructured surfaces have also
attracted significant research attention.
This symposium aims to capture the advances in the following aspects of
nanostructured surfaces:
a) Novel processes and techniques for the development of nanostructured coatings
b) Nanostructured metallic, organic, and ceramic coatings
c) Nanostructured high entropy alloy coatings
d) Multi-layered and nanostructured composite coatings
e) Corrosion resistant, anti-friction, wear and galling resistant, thermal
barrier, and hydrophobic nanostructured coatings
f) Nanostructured coatings for biomedical applications
g) Nanostructured surfaces for clean energy generation
h) Multi-scale characterization and understanding the structure-property
correlations
