Tools and mechanical parts - Nitriding and nitrocarburizing of ferrous products

Le présent document fixe les conditions des traitements de nitruration de pièces mécaniques et outillages en acier et en fonte grise ainsi que les indications à porter sur les plans. Des rappels sur les procédés de nitruration et des essais de contrôle associés sont fournis en annexes. Les traitements thermochimiques de nitruration sont réalisés en vue d'améliorer les résistances des pièces à l'usure par abrasion et par adhésion, à la fatigue superficielle sous charge modérée (roulement, glissement) , à la fatigue principalement en flexion et torsion, et dans certains cas à la corrosion.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
