1. Miletić Aleksandar. Razvoj nanoslojnih i nanokompozitnih metal-nitridnih prevlaka.

Degree: 2015, University of Novi Sad

Razvijene su TiAlN/TiSiN i CrAlN/TiSiN nanoslojne prevlake u kojima je napravljen spoj nanoslojnog i nanokompozitnog dizajna. Akcenat je stavljen na proizvodnju prevlaka visoke tvrdoće i visoke otpornosti na lom. Proučavane su i jednoslojne TiAlN, nanokompozitne TiSiN i višeslojne TiAlN/TiSiN prevlake kako bi se utvrdilo kako dizajn utiče na osobine prevlaka. Sve prevlake pripremane su sa jednim, dva i tri stepena rotacije. Pokazano je da dizajn i vid rotacije značajno utiču na mikrostrukturu i teksturu prevlaka, a time na njihove mehaničke osobine, otpornost na lom, adheziju između prevlake i podloge, topografiju površine i tribološko ponašanje. Nanoslojne i nanokompozitne prevlake odlikuju se kompaktnom nanokristalnom mikrostrukturom, dok jednoslojne TiAlN prevlake imaju stubastu strukturu sa kristalnim zrnima veće veličine. Pri prelasku sa jednog na više stepeni rotacije mikrostruktura prevlaka postaje kompaktnija sa kristalnim zrnima manje veličine i manjom poroznošću. U skladu sa tim, najmanju hrapavost, najveću tvrdoću, najveću otpornost na lom i najveću otpornost na habanje imaju nanoslojne i nanokompozitne prevlake pripremane sa dva i tri stepena rotacije.

With the aim to develop hard coatings characterized by both, high hardness and high resistance to cracking, synergy between nanolayered and nanocomposite design was made and nanolayered TiAlN/TiSiN and CrAlN/TiSiN coatings were produced. Monolayer TiAlN, nanocomposite TiSiN and multilayer TiAlN/TiSiN were also studied in order to find the relation between the coating design and their properties. All coatings were deposited with 1-fold, 2-fold and 3-fold rotation. It is shown that coating design and type of rotation have great influence on coating microstructure and texture, and in this way on their mechanical properties, resistance to cracking, adhesion between coating and substrate, surface topography and tribological behavior. Nanolayered and nanocomposite coatings are characterized by compact nanocrystalline microstructure, while monolayer TiAlN coatings have columnar structure with larger crystalline grains. By increasing the number of rotational degrees from 1-fold to 3-fold size of crystalline grains decreases and microstructure becomes more dense. Therefore, nanolayered and nanocomposite coatings deposited with 2-fold and 3-fold rotation are characterized by the highest hardness, highest resistance to cracking, highest wear resistance and the smoothest surface topography.

2. Terek Pal. Unapređenje kvaliteta alata za livenje pod pritiskom primenom tehnologija inženjerstva površina.

Degree: 2016, University of Novi Sad

Proučavane su koroziona postojanost i tendencija lepljenja različitih materijala u kontaktu sa tečnom Al–Si–Cu legurom. Ispitivanjem su obuhvaćeni čelik za rad na toplo, plazma nitrirani čelik i dupleks slojevi sa CrN, TiAlN, TiAlSiN i CrAlN prevlakama, različitog nivoa površinske hrapavosti. Za ispitivanja pomenutih fenomena primenjena je metoda izvlačenja, koja je unapređena kako bi se povećale njena tačnost i verodostojnost simulacije procesa livenja. Korozioni efekti su pojačani tako što su uzorci osim kratkog kontakta sa odlivkom zadržavani i u dužim periodima u kontaktu sa tečnom legurom (5 i 20 min). Uprkos opštim stavovima, za ispitivane materijale je ustanovljeno da su sile izvlačenja uzoraka iz Al–Si–Cu odlivaka nezavisne od njihovog hemijskog sastava. Uticaj hrapavosti je izražen kod uzoraka sa prevlakama kod kojih pri smanjenju hrapavosti dolazi do povećanja sile izvlačenja. Sve ispitane prevlake su sklone mehaničkom lepljenju Al–Si–Cu legure za svoje površine, ali sa aspekta korozije u tečnom metalu značajno prevazilaze performanse čelika i plazma nitriranog sloja. Duži kontakt livene legure sa površinama prevlaka uzrokovao je niže vrednosti sila izvlačenja, što je posledica oksidacije površina prevlaka. Ustanovljeno je da su ispitivane prevlake inertne ka tečnoj leguri aluminijuma. Međutim, dolazi do oksidacije i korozije materijala podloge kroz greške rasta koje su prisutne u prevlakama. Stečena znanja o identifikovanim mehanizmima habanja i propadanja zaštitnih slojeva prevlaka poslužiće daljem razvoju dupleks slojeva namenjenih za zaštitu alata za livenje pod pritiskom.

Corrosion resistance and soldering tendency of different materials in molten Al–Si–Cu alloy were studied. Hot-working tool steel, plasma nitrided steel and duplex layers with CrN, TiAlN, TiAlSiN and CrAlN top coatings, which were produced to various degree of surface roughness, were covered by the study. An ejection test was employed for investigation of the concerned phenomena. The ejection test was improved in order to increase its accuracy and the reliability of process simulation. Samples were examined in both short and extended periods of contact (5 and 20 min) with liquid casting. Casting solidification was extended in order to intensify the corrosion effects. Contrary to common findings, it was found that the ejection force of the investigated materials does not depend on their chemical composition. For the coated samples, a pronounced dependence of the ejection force on the surface roughness was found. The ejection force increases with decrease in surface roughness. All investigated coatings are prone to mechanical soldering by Al– Si–Cu alloy. Still, their corrosion resistance substantially exceeds the corrosion resistance of steel and plasma nitrided layer.…

For the coatedsamples, a pronounced dependence of the ejection force on the surfaceroughness was found. The ejection force increases with decrease in surfaceroughness. All investigated coatings are prone to mechanical soldering by Al–Si–Cu alloy. Still, their corrosion resistance substantially exceeds the corrosionresistance of steel and plasma nitrided layer. Longer exposure of coatedsamples to cast alloy induced lower ejection forces, which is a consequenceof coatings oxidation. It was found that the investigated coatings are inert toliquid aluminium. However, the underlying material undergoes oxidation andcorrosion through coating growth defects. The findings concerning the wearmechanisms of protective layers support further development of duplex layersintended for die casting tools protection.
