Predvideni študijski rezultati:

Intendeded learning outcomes:

- Usposobiti študente za razumevanje,
načrtovanje in izvedbo postopkov toplotne
obdelave, pri katerih kovinske dele namerno
izpostavimo temperaturno-časovnem ciklusu,
da dosežemo želeno mikrostrukturo in s tem
želene mehanske, fizikalne in kemijske lastnosti;
- usposobiti študente za razumevanje in
načrtovanje ter izvajanje postopkov inženiringa
površin, ki temeljijo na novih spoznanjih v
okviru fizike trdne snovi in termodinamike
procesov, na razvoju senzorjev in na razvoju in
uporabi matematičnih modelov in programske
opreme za vodenje procesov;
- veliko število obstoječih postopkov toplotne
obdelave, modificiranja in prekrivanja površin,
ki jih koristimo s ciljem povečati odpornost proti
obrabi in trajni dinamični trdnosti strojnih
elementov in orodij, se vse bolj uveljavlja v
industrijski praksi, pojavljajo pa se tudi novih
postopki;
- vsak od postopkov je specifičen, tako z vidika
podobnosti mehanizmov in pogojev obrabe kot
tudi z vidika uporabnosti obdelovanih
materialov in tehnoloških posebnosti uporabe.
Zato je pravilni izbor postopka vedno povezan
s celovito analizo vseh vplivnih dejavnikov;
- doktorand bo usposobljen za delo: v
raziskovalnih laboratorijih za materiale, na
inštitutih in centrih za razvoj proizvodov in
tehnologije v industriji;
- kot predavatelj na fakultetah in srednjih šolah, v
proizvodnji, v oddelkih za karakterizacijo
materialov v kontroli kakovosti v industriji;
- kot podjetnik v ustanavljanju in vodenju
podjetja, temelječega na znanju;
- aktivno in kritično spremljanje razvoja novih
metod uporabe materialov na področju
avtomobilizma, energije in ekologije.

- Tto educate students for understanding and
planning and conducting of processes of heat
treatment at which metallic parts intentionally
emphasize temperature-time cycle, that we
achieve desired microstructure and mechanical,
physical and chemical characteristics wanted
with this;
- to educate students for understanding and
planning and implementing of processes of
surface engineering that based upon on new
findings in frame of solid-state physics and of
thermodynamics of processes, on development
of sensors and on development and uses of
mathematical models and software for direction
of processes;
- namely, extensive number of existent
procedures of heat treatment, modifications and
coverings of surfaces, which them serve with
goal to increase resistance against wear out and
fatigue strength of machine elements and of
tools, all are asserting oneself more in industrial
practice, and new procedures also occur;
- each of procedures is specific so from point of
view of similarity of mechanisms and of
conditions of wear out, as also from point of
view of usability of treated materials and of
technological specialities of use. That is why
correct selection of procedure is connected with
complete analysis of all influential factors always;
- doctor of this direction is trained for work: in
research laboratories for materials, on
institutes and centres for development of
products and technology in industry, as
lecturer on faculties and secondary schools;
- in production, in departments for
characterization of materials in control of
quality in industry, as entrepreneur in
establishing and direction of company based on
knowledge;
- actively and critically monitoring the
development of new methods of using materials
in the automotive, energy and ecology field.
