Catalogue of Polosh Technologies 2012 Part 2 - Polonia

� the technology of moulding sands, gravity and pressure die casting, investment casting
and lost foam process;
� reclamation and recycling of foundry waste;
� rapid prototyping, 3D scanning, simulation of the pouring process, solidification and
stress distribution;
� studies of:
� high temperature liquid state, and the reactivity and stability of liquid metals in
contact with solid materials,
� mechanical properties and structure of cast materials, and physico-chemical and
technological parameters of basic and auxiliary materials;
� defects in castings.
The significant scientific and cognitive achievements of the Institute during the last four-year
period include:
� determination of relationship between the manufacturing parameters and
performance characteristics of titanium implants made by precision casting and
isostatic compaction,
� development of the mechanism of pressure infiltration of porous bodies and the
distribution of reinforcing phase particles to manufacture heterogeneous products
with local reinforcement,
� determination of the effect of alloying elements and heat treatment on the structure
and properties of spheroidal and vermicular graphite cast irons, including ADI
(Austempered Ductile Iron),
� development of physico-chemical backgrounds of the synthesis of a water-based
binder of the next generation for precision casting,
� explanation of mechanisms governing the stability and reactivity of nitrides in contact
with liquid metals and alloys,
� determining the mechanism of multi-stage heat treatment of selected alloys,
� simulation of the solidification and crystallisation processes of monolithic and
composite materials (including in vitro and in situ composites – on the example of a
regular structure as a concentration-related picture of temperature microfield) and
modelling the crack-formation process in cast alloys in a spatial state of stress,
� studies of the mechanism responsible for the formation of ordered porosity in highporosity
media and development of a mathematical model explaining this
phenomenon,
� determining the mechanism of isothermal transformation in ADI with nickel and
copper additions austempered in salt bath,
� studies of the effect of the conditioning regime of sodium silicate glaze on the
structure, the value of "zeta" potential and cohesive properties of hydrated sodium
silicate serving as a complex binder for the chemically hardened moulding sands,
