Metallic and other inorganic coatings — Surface treatment, metallic and other inorganic coatings — Vocabulary
1Key Takeaways
This document defines the terms related to the general types of surface-finishing processes. Emphasis is placed on practical usage in surface-finishing technology in the metal-finishing field. This document does not include terms for porcelain and vitreous enamel, thermally sprayed coatings and galvanising for which sp…
2Expert Interpretation
Professional interpretation of ISO 2080:2022 International Standard Terminology for Metal and Inorganic Coatings, covering the definition and classification of surface treatment technologies such as electroplating, chemical plating, and anodizing, including a systematic analysis of coating processes, detection methods, and industry-specific vocabulary.
Overview of the standard framework
ISO 2080:2022 is the core terminology standard in the field of metallic and other inorganic coatings. The fourth edition has made technical revisions to the 2008 edition. The main changes include:
- 21 new modern coating technology terms
- Optimization of the original terminology classification system
- Delete 17 obsolete process expressions
Analysis of core process terms
| Process type | Definition points | Typical applications |
|---|---|---|
| Electroplating(3.1.6) | Deposition of metal/alloy coatings on substrates by electrolysis | Automotive parts corrosion protection |
| Chemical plating(3.1.1) | Metal coating deposition by chemical reduction reaction | Surface treatment of electronic components |
| Anodizing(3.2.10) | Functional oxide film formation by electrolytic oxidation | Surface treatment of aluminum profiles |
Technology evolution analysis
The standard reflects the three major development trends of coating technology:
- Environmental protection: New green process terms such as cyanide-free electroplating and trivalent chromium passivation
- Complexification: clarify the definitions of multi-layer plating (3.2.156) and composite coating (3.2.82)
- Precision: standardize the terms related to pulse plating (3.2.178) and nano-coating
Implementation suggestions
Note when applying this standard:
- Distinguish the potential difference between anodic protection (3.2.11) and cathodic protection (3.2.35)
- The new version deletes the expression "electroless plating" and uniformly uses autocatalytic plating (3.1.1.1)
- The hydrogen embrittlement terminology system (3.2.130) adds a new classification of environmental hydrogen embrittlement (EHE)
