7) „Studies and development of modern technology of the cast
materials resistant to thermal fatigue".
Based on physico-chemical interactions in a ‘liquid metal - coating - metal mould’ system, a new
generation of protective and insulating coatings has been developed. The aim of the project is
to develop an advanced technology for the manufature of innovative cast materials (ferrous
alloys) of controlled structure, modified with alloying elements and offering increased
resistance to thermal fatigue under the cyclic changes of temperature. The project also
anticipates the development of a modern method for the determination of boundary
parameters and dynamics of cyclic changes in temperature and state of stress in the large
objects in motion; a prototype test stand to examine the destruction of iron-based alloys under
the conditions of cyclic temperature changes; a database of static and dynamic operating
parameters of the cast heavy equipment parts for the domestic copper metallurgy industry.
The outcome of the project is expected to contribute to the reduced operating cost of
numerous devices used by the steel industry, automotive and glass industries, and many other
sectors of the domestic industry.

8) „Improving the reliability of lead-free solder joints in electronic
packages."
The aim of the project is meeting the EU directives prohibiting the use of hazardous substances
in electronic products, obtained through improved reliability of lead-free solder joints in
electronic packages, manufactured from the environmentally friendly new generation of leadfree
solders, and conducting a systematic and comprehensive comparative study of the
properties of various types of solder joints produced in laboratory scale and in industry, to
identify the causes accounting for the loss of reliability of the connections, and to determine
the influence of material characteristics, process parameters and other identified factors on the
structure, and physical, mechanical and functional properties of various types of solder joints.
Another aim of the project is development and improvement of the soldering process control
procedures and quality evaluation of solder joints, as well as the development of solutions to
improve the reliability of connections in electronic packages.
