The effect of various atmospheric parameters on the corrosion mechanism press-hardened steel (PHS) coated with Al-Si (AS) was studied. Quantitative models composition soluble and stable products were developed. A high chloride concentration led to a localized due presence cracks in coating. Increased resistance silicon-rich Al8Fe2Si AlFe at expense Al5Fe2 phase low silicon content shown. Under low-chloride-deposition conditions, coating exhibited good provided sufficient protection underlying steel. formation more local anodes cathodes under conditions lower relative humidity reduction depth pits substrate. Constant sulphate deposits surface critical for acceleration cracks.

Hydrogen Embrittlement of Galvanized Press-Hardened Steels: A Review

Metals, Год журнала: 2024, Номер 14(11), С. 1285 - 1285

Press-hardened steels (PHS), as an alternative to traditional and aluminum alloys, combine great mechanical performance with low manufacturing costs. PHS are martensitic ultimate tensile strength (UTS) up 2000 MPa. These commonly coated zinc-based coatings (PHS GI) consisting of multiple Zn–Fe phases enhance corrosion resistance. However, similar all high-strength steels, known for their elevated susceptibility hydrogen embrittlement (HE). Absorption atomic into the steel lattice can lead a transition from ductile brittle fracture mechanism decrease stress necessary initiation. This review examines microstructure GI focus on how process influences key parameters coating. The material’s HE is discussed in following sections, along potential introduction through atmospheric environments. relationship between content its effects behavior discussed, GI. areas future research development increased resistance proposed.
