The Metallographic Research Laboratory (P3) deals with the following research work:
- preparation of metallographic samples,
- hardness measurements using the micro-impressions method,
- microscopic observations using light (LM) and scanning electron microscopy (SEM),
- determining the chemical composition in micro-areas (SEM / EDS).
The research work performed in the Metallographic Research Laboratory is carried out as part of scientific research conducted by the employees of the Department of Materials Science and the Research and Development Laboratory for Aerospace Materials and staffs of other organizational units of Rzeszów University of Technology (PhD students, postdocs , staff from other units involved in industrial projects carried out with group of RUT personnel) and commissioned by external clients - universities: Kraków University of Technology; University of Science and Technology in Kraków (AGH); Silesian University of Technology, Warsaw University of Technology, University of Silesia and production plants: WSK "PZL-Rzeszów" S.A .; Instytut Energetyki Ceramics Division "CEREL" - Boguchwała; Metal Works "DEZAMET"; BURY Technologies; HISPANO-SUIZA - Sędziszów Małopolski, PPHU MLECZMASZ Sp. z o.o., Borg Warner Turbo Systems Poland Sp z o.o. - Jasionka, Factory of Paints and Varnishes Śnieżka -Brzezina; Zakłady Metalowe ERKO - Czeluśnica, MTU Aero Engines Polska - Rzeszów; NORBERT Polska Sp. z o.o. - Rzeszów; ZM INVEST S.A. - Ropczyce.
Research for 4 companies (Pratt&Whitney Rzeszow; CEREL and Borg Warner) is carried out under permanent cooperation agreements.
The basic equipment of the metallographic research laboratory includes:
