The study of the electric erosion phenomenon of contact materials is significant to improve its service life and reliability[1-5].
In recent years, many researchers have been interested in the study of arc erosion, surface morphologies and material transfer phenomenon of noble metal alloy contact materials[6-9].
In order to study the arc erosion mechanism, the surface morphologies, microstructures and material transfer phenomenon of Pt-Ir-Zr alloy contact materials were carried out by electrical contact test machine and SEM in present paper.

Due to the excessive cost of new materials, a new method of design had to be sought and new materials introduced.
The use of waste materials, particularly RAP in the construction of pavements has benefits in not only reducing the amount of waste materials requiring disposal but can also provide construction materials with significant savings over new materials [5].

Preface Optical Materials is a peer-reviewed scientific journal that publishes original papers and review articles on the design, synthesis, characterisation and applications of materials, suitable for various optical devices.
The journal also publishes papers about physical and chemical properties of such materials and their applications.
Aiming to the advances of Optical Materials and Circuit Design, 2012 International Conference on Future Optical Materials and Circuit Design (FOMCD 2012) is an annual conference to call together researchers, engineers, academicians as well as industrial professionals from all over the world to present their research results and development activities in Optical Materials and Circuit Design.
The papers come from both academia and industry reflecting the international flavor of this event in the topics of Optical Materials and Circuit Design, Material Science and Engineering, Nanomaterials Synthesis and Properties, Nano Devices and System, Nano materials, Technologies for Applications, Circuits and Systems, Mechanical Engineering, Industrial Electronics, etc.
