Mechanical and Tribological Characterization of WC-Co and WC-AISI 304 Composite...
Vilhena, Luis; Domingues, Bruno; Fernandes, Cristina; Senos, Ana; Ramalho, AmilcarTungsten carbide-based composites are, in many cases, the materials of choice in applications requiring high wear resistance. In the present research work, the mechanical characterization of the WC-Co and WC-AISI 304 composites was carried out, with evaluation of the hardness and fracture toughness and tribological characterization of the composites that included the study of friction and wear rate coefficient ...
Mechanical and Tribological Characterization of a Bioactive Composite Resin
Carneiro, Elsa Reis; Coelho, Ana Sofia; Amaro, Inês; Paula, Anabela Baptista; Marto, Carlos Miguel; Saraiva, José; Ferreira, Manuel MarquesDespite developments and advances in dental materials which allow for greater restorative performance, there are still challenges and questions regarding the formulation of new compositions and chemical reactions of materials used in restorative dentistry. The aim of this study was to assess and compare the mechanical and tribological characteristics of a bioactive resin, a composite resin, and a glass ionomer....
