P. S.; HERNANDES, V. T.; BRESSIANI, A.H.A.; BRESSIANI, J.C.Specific properties of structural ceramics such as their mechanical and thermal stability permit their use in high-speed cutting processes that involve deep cuts and low wear rates. The process by which wear occurs in tribological contacts is complex and cannot be explained by one simple wear mechanism. The contribution of different mechanisms to the total wear of a component is related to the mechanical and chemical properties of both the materials and the contact interface. In this investigation, diffusion tests were carried out to determine the influence of chemical interactions between alumina composite and gray cast iron, without the interference of mechanical wear mechanisms. These tests were carried out at 1100°C using static couples. The tests did not generate a strong metal–ceramic interface, indicating that the alumina composites were chemically stable under the test conditions.Artigo IPEN-doc 16088 Diffusion studies involving nanometric and submicrometric base alumina composites with gray cast iron2010 - TONELLO, KAROLINA P. dos S.; TROMBINI, VANIA; BRESSIANI, ANA H. de A.; BRESSIANI, JOSE C.
