“…04017-p. 3 higher chromium content (more than 5.6 mass percent) presented strong interaction characteristics with nitrogen [17]. Therefore, 14.25wt% Cr in the steel was high enough for interacting with nitrogen to form chromium nitride.…”

“…Martensitic stainless steels are widely used as automotive components, boilers, cutting tools, dental and surgical instruments, machinery components, and structural parts due to their good mechanical properties [9,17]. Even though nitrided austenitic stainless steels have established themself in many industrial applications, nitrided martensitic stainless steels remain a good choice for low temperature applications and mildly corrosive environments [12].…”

“…Não se observa presença de camada branca ou de nitretos em contornos de grão. A morfologia de formação da camada nitretada para o aço inoxidável 17-4PH, tanto em tela ativa quanto em plasma/DC, coincide com a morfologia apresentada na literatura para aços inoxidáveis martensíticos [16][17], e tem seu mecanismo de crescimento controlado pelo teor de cromo no aço e pela necessidade de precipitação de nitretos de cromo durante seu crescimento [18][19]. Comparando a microestrutura da amostra nitretada dentro e fora da Tela Ativa é verificado que a amostra nitretada em Plasma/DC, apresenta uma zona de difusão maior que na amostra nitretada em Tela Ativa.…”

“…As espessuras das camadas obtidas para as temperaturas de 623, 673 e 773 K, foram respectivamente 30, 45 e 130 m, semelhante aos resultados obtidos na nitretação iônica convencional, tanto nesse trabalho como por P. Corengia [11] e Pinedo [12]. Diferenças microestruturais foram observadass, principalmente para as amostras nitretadas em 673K e 773K.…”
