Thesis topic proposal

Surface treatments on steels to enhance dissolution resistance in metal melts while maintaining good wettability

THESIS TOPIC PROPOSAL

Institute: University of Miskolc
material sciences
Antal Kerpely Doctoral School of Materials Science and Technology

Thesis supervisor: Márton Benke
Location of studies (in Hungarian): UM, Intitue of Physical Metallurgy, Metallforming and Nanotechology
Abbreviation of location of studies: AVK

Description of the research topic:

Steel (and metals, in general) substrates exhibit good wettability with metal melts due to the similar bonds. However, when immersed in the melt, dissolution of substrate atoms usually occurs, which leads to the degradation of substrate. To enhance the dissolution resistance of the substrate, ceramic coatings are applied as barriers in such applications, where good wetting is not a requirement. When good wettability must be maintained (for instance, soldering nozzles), the enhancement of dissolution resistance is not that easy. The aim of the PhD research is to test novel surface modification methods of steel substrates to enhance the dissolution resistance against metal melts whilst maintaining good wettability. The required facilities for surface modification, the physical simulation of dissolution and microstructure analysis are provided.
