Abstract

Grade 315 steel (Fe-2.9 Cr-1.7 W- 0.7 Mo -0.3 Mn-0.3 Si-0.2 V- 0.1 Ni-0.13 C-0.01 N) was chromized by the halide-activated pack cementation (HAPC) process. Key process parameters, i.e., coating temperatures and pack compositions, were investigated. Ammonium chloride-activated packs in the 700-1000°C range produced coatings nominally in the 1-8 μm range, as determined by optical and scanning electron microscopy (SEM). Coatings applied in the 900-1000°C temperature range resulted in Cr-rich coatings. The predominant phase in the coating was identified as Cr₂₃C₆ by X-ray diffraction. In addition, the presence of chromium nitride, Cr₂N, was observed in the coating.
