Dj. Bowe et al., OPTIMIZATION OF NITROGEN-HYDROGEN ATMOSPHERE COMPOSITION FOR SINTERING CARBON-STEEL COMPONENTS, Heat treatment of metals, 21(4), 1994, pp. 93-96
An option to traditional generated atmospheres, nitrogen-hydrogen mixt
ures are employed to sinter carbon-bearing steel PM components with co
nsistent quality, close dimensional tolerances and good wear resistanc
e. However, careful selection and control of optimum gas composition i
s necessary to minimise surface decarburisation and hardness loss.
