Cercetări privind ameliorarea proprietăților și creșterea fiabilității unor oțeluri folosite în construcția utilajelor utilajelor metalurgice
(Universitatea "Dunărea de Jos" din Galați, 2005)Tratamentele termochimice sunt deosebite prin caracteristicile pe care le imprimă straturilor superficiale ale pieselor (duritate, rezistența la uzura și la coroziune). O serie de proprietăți interne ( ale materialului de ... -
Diffractometry Analysis on Non-Conventional Treated Steels after Tribological Tests
(Universitatea ”Dunărea de Jos” din Galați, 2009)Two steel grades were subjected to a nitro-carburized thermo-chemical treatment after thermo-magnetic treatments. The contact was studied employing the concept of tribosystem and tribomodel. The structural aspects into ... -
Monitoring the Influence of Thermomagnetic Treatment on the Ion Nitrided Layer Using Microhardness Curves, for 42MOCR11 Steel Grade Case
(UDJG, 2010)Each of the stages of heat treatment in magnetic field (AC or DC) influences the hardness and durability of different steels. This influence is extended in the case of the measured microhardness values obtained in the ... -
On Tribological Behaviour of Thermo-Chemical Treated Steels after Thermo-Magnetic Treatments
(Universitatea ”Dunărea de Jos” din Galați, 2008)The paper presents an analysis on two grades of steel, subjected to nitrocarburized or nitrided thermo-chemical treatment after different thermomagnetic treatments. Based on the concept of tribosystem, pairs of steel rollers ... -
The Behaviour of Two Non-Conventionally Treated Steels During Corrosion Process
(Universitatea ”Dunărea de Jos” din Galați, 2009)This paper presents an analysis on two steel grades, subjected to nitriding thermo-chemical treatment after classic / thermo-magnetic treatments (in direct current/alternative current). It was estimated the durability of ...
