Project abstract
New electric contact material is crucial for suitable product development in smart grids. The new materials should combine several, sometimes contracting properties such as low contact resistance, high wear resistance and low friction. In this project, (i) a series of combinatorial tools and platforms have been developed for rapid and economical screening new suitable materials for contact application, and (ii) once identified, suitable materials candidates will be studied in more detail. A batch of Ag-M alloy films will be combinatorial screened. Nano-structure materials including Ag based delafossite materials, nano-composite materials with hard particle embedded in Ag matrix, nano porous Ag filling with lubricants and solid lubricants (AgI and graphene) are also the study targets for electrical contact applications.
Summary of work
Systematic study of AgNb, AgW, AgAl, and AgI coatings for the electrical contact applications.
Developed a process for AgFeO2 deposition. This material maybe excellent for decreasing friction coefficient in composite Ag films.
Investigated graphene lubricant effect for reducing friction and wear on contact sliding silver surface.
Involved in Mamoun Taher's project on the bulk Ag-based materials for the electrical contacts applications
