Estudo do efeito dos tratamentos duplex de nitrocementação e deposição de filmes DLC dopados com nitrogênio e silício nas propriedades tribológicas do aço M2
(Universidade Federal de São Carlos, 2023-02-27)
DLC films have been the focus of recent research due to chemical inertia, low friction coefficient, high hardness, and interesting optical properties. But due to its problem of poor adhesion on metallic substrates, some ...
Estudo do Comportamento do Aço Inoxidável Austenítico AISI 321 Nitretado e Nitrocementado a Plasma Sob Solicitações de Desgaste, Corrosão e Fadiga
(Universidade Federal de São Carlos, 2023-09-01)
The AISI 321 austenitic stainless steel is used in the chemical, petrochemical and fertilizer industries, as it can operate at high temperatures (above 600 °C) and under corrosive media. However, it has poor tribological ...
Desenvolvimento de dispositivos eletroquímicos descartáveis e reutilizáveis para detecção de biomarcadores de interesse clínico
(Universidade Federal de São Carlos, 2023-11-08)
In recent years, the search for new electrochemical devices that allow reliable, fast, easily accessible, highly sensitive, miniaturized and portable analyses has been required. Furthermore, they enable point-of-care ...
