Abstract

Przedmiotem zgłoszenia jest sposób dyfuzyjnej obróbki stali odpornej na korozję metodą azotowania lub azotonawęglania obejmujący etap załadunku obrabianego elementu do pieca obróbczego, etap wprowadzania atmosfery obróbczej, etap ogrzewania atmosfery obróbczej do temperatury, w której jest prowadzony proces azotowania lub azotonawęglania gazowego i etap wprowadzania aktywatora powierzchni obrabianego przedmiotu, przy czym atmosfera obróbcza do azotowania gazowego zawiera amoniak jako donor azotu, natomiast atmosfera obróbcza do azotonawęglania gazowego zawiera amoniak jako donor azotu oraz tlenek węgla i/lub dwutlenek węgla będące donorem węgla. Sposób charakteryzuje się tym, że aktywator będący alkoholem lub mieszaniną alkoholu z wodą w postaci gazowej lub ciekłej wprowadza się do atmosfery obróbczej po raz pierwszy, gdy atmosfera obróbcza osiągnie temperaturę docelową dla prowadzonego procesu, a następnie cyklicznie przez cały czas trwania procesu azotowania lub węgloazotowania gazowego, przy czym stężenie alkoholu jest nie mniejsze niż 5% obj., zaś ilość podawanego aktywatora jest nie mniejsza niż 10 ml na jeden proces obróbki dyfuzyjnej.
