• Influence of plasma nitriding with a nitrogen rich gas composition on the reciprocating sliding wear of a DIN 18MnCrSiMo6-4 steel 

      Dalcin, Rafael Luciano; Rocha, Alexandre da Silva; Castro, Victor Velho de; Oliveira, Leonardo Fonseca; Neves, Júlio César Klein das; Silva, Carlos Henrique da; Malfatti, Célia de Fraga (2021) [Artículo de periódico]
      In this study, the sliding wear of a DIN 18MnCrSiMo6-4 continuous cooling bainitic steel plasma nitrided with a nitrogen rich gas composition was investigated. To evaluate the influence of processing time and temperature ...
    • Microstructure and wear properties of a low carbon bainitic steel on plasma nitriding at different N2-H2 gas mixtures 

      Dalcin, Rafael Luciano; Rocha, Alexandre da Silva; Castro, Victor Velho de; Neves, Júlio César Klein das; Silva, Carlos Henrique da; Torres, Ricardo Diego; Nunes, Rafael Menezes; Malfatti, Célia de Fraga (2022) [Artículo de periódico]
      For the first time, the influence of gas mixture on first damage resistance of a plasma nitrided DIN 18MnCrSiMo6-4 bainitic steel was investigated. Samples were nitrided at 500 °C with three different N2 -H2 gas mixtures, ...
    • Oxide formation on NiTi surface : influence of the heat treatment time to achieve the shape memory 

      Hansen, Alana Witt; Beltrami, Lílian Vanessa Rossa; Antonini, Leonardo Marasca; Villarinho, Denis Jardim; Neves, Júlio César Klein das; Marino, Cláudia Eliana Bruno; Malfatti, Célia de Fraga (2015) [Artículo de periódico]
      Several studies regarding superficial treatments of Nitinol (NiTi) shape-memory have been developed aiming to the improve corrosion resistance and to block the Ni release to adjacent tissues. The necessary heat treatment ...
