    • A Comparation of Standardized Methods for Lubrication Failure Determination 

      Spânu, Constantin; Rîpă, Minodora; Ştefănescu, Ioan; Deleanu, Lorena (Universitatea "Dunărea de Jos" din Galaţi, 2007)
      Lubricants are used to prevent wear between moving parts and to resist to high pressure between them. There are standardized testing methods that determinate the wear of the contact pair pieces and the pressure that leads ...

    • Flammability Test Data in Risk Assessment 

      Deleanu, Lorena; Buzoianu, Dragoș; Crăciunoiu, Ștefan; Rîpă, Minodora; Spânu, Constantin (Universitatea ”Dunărea de Jos” din Galați, 2008)
      This paper reviews the most recent information on standards dealing with testing fire-resistance of hydraulic fluids in order to emphasis the importance of selecting hydraulic fluids including as basic criteria of reducing ...

    • Flammability Tests on Hot Surfaces for Industrial Fluids 

      Deleanu, Lorena; Buzoianu, Dragoş; Rîpă, Minodora; Crăciunoiu, Ştefan; Drug, Adina (Universitatea "Dunărea de Jos" din Galaţi, 2007)
      Industrial fluids have to be evaluated not only for their performances as load capacity, durability, but also for their potential risk including ignition. Based on a solid documentation the authors point out the significance ...

    • Influence of Sliding Speed and Average Pressure in Dry Regim Upon Wear of Composite with PA and Micro Glass Spheres 

      Maftei, Laura; Deleanu, Lorena; Andrei, Gabriel (Universitatea ”Dunărea de Jos” din Galați, 2009)
      The papers presents the wear results of testing a set of composites PA + 1% black carbon + x% micro glass spheres, where x is the micro glass sphere concentration (x=0, 5, 10, 20, 30wt) using a pin-on-disc tribotester, for ...

    • Overview on the Implementation of Tree Test Methods for Conformity Assessment of Fluids 

      Rîpă, Minodora; Deleanu, Lorena; Chiculiță, Simona (Universitatea ”Dunărea de Jos” din Galați, 2006)
      This paper presents three test methods for conformity assessment of technical fluids, all included in international, European and Romanian standards and their relevance for work security and health.

    • Particularities of Rubber Lip Seals Used for Pneumatic Linear Drives 

      Podaru, Geanina; Ciortan, Sorin; Bîrsan, Iulian; Deleanu, Lorena (Universitatea ”Dunărea de Jos” din Galați, 2009)
      The paper presents some particular aspects of reciprocating rubber lip seals for pneumatic linear drives. This study is focused on the following tribological aspects: friction variation under linear velocity, determination ...

    • Rapeseed Oil Flammability on Hot Surface 

      Deleanu, Lorena; Ciocan, Sorin; Șolea, Liviu (Universitatea ”Dunărea de Jos” din Galați, 2009)
      The paper presents the tests and results upon rapeseed oil flammability on hot surface. The oil samples were obtained from a rapeseed oil after a dewaxing process. There were established temperature ranges for which the ...

    • Statistical Assessment of Surface Quality Using 3D Profilometry Parameters 

      Deleanu, Lorena; Andrei, Gabriel; Ciortan, Sorin; Cantaragiu, Alina; Besnea, Aida; Trufașu, Cătălin; Podaru, Geanina (Universitatea ”Dunărea de Jos” din Galați, 2009)
      he paper presents a statistical analysis for quality assessment of metallic surfaces and coating in order to use the conclusions for improving coating technology. Surface investigation was done with the help of a 3D ...
