Description (English):

This document specifies a method and requirements for plasma nitriding and follow-up PVD hard coatings intended for use in cold-work moulds. This document provides the necessary information, such as the original structure of nitriding steels, process requirements, surface quality and adhesion of duplex PVD coatings, to create an optimal combination of high performance.

Abstract

Overview

ISO 24674:2022 specifies a method and requirements for combining plasma nitriding with follow‑up PVD hard coatings (a duplex treatment) for cold‑work mould steels. The standard sets out metallurgical prerequisites, process controls, surface quality limits and adhesion evaluation criteria to achieve an optimal duplex system that improves wear resistance, loading capacity and coating lifetime for cold‑work tools used e.g. in the automotive sector.

Key topics and technical requirements

Substrate requirements
- Typical acceptance hardness: HRC45 to HRC60 (Rockwell test per ISO 6508‑1).
- Original microstructure classes (1–5) are defined by optical microscopy (×500); Classes 1–2 are acceptable.
Plasma nitriding
- Surface roughness (Rz) before nitriding: **
