ISO 14924:2005 specifies the treatment and finishing of thermally sprayed coatings. It is applicable to different types of mechanical post treatment, chemical treatment, and thermal treatment, including chip cutting and other mechanical processes, to sealing, pickling and painting, and fusing, diffusion annealing and hot isostatic pressing.

Overview

EN ISO 14924:2005 - Thermal spraying: Post‑treatment and finishing of thermally sprayed coatings - provides practical guidance for treating and finishing coatings produced by thermal spray processes. Published by CEN (adopting ISO 14924:2005), the standard covers mechanical, chemical and thermal post‑treatment methods applicable to a wide range of thermally sprayed materials and service requirements.

Key topics and requirements

Scope: Procedures for mechanical post‑treatment (chip cutting, grinding, milling, drilling, belt finishing), chemical treatment (sealing, chemical conversion, painting) and thermal treatment (fusing, diffusion annealing, hot isostatic pressing).

Mechanical post‑treatment:

Tool selection and cutting strategies for thermally sprayed coatings (different microstructure and embedded hard phases require harder tool materials - e.g., hard metals and CBN for very hard coatings).
Guidance on turning, milling, grinding and belt finishing; preferred use of wet grinding to avoid overheating and coolant penetration.
Annexes provide estimated machining parameters (cutting speeds, feeds, depths) and recommended grinding wheels/abrasives.
Special processes: shot peening (to densify and induce compressive stress), brushing, polishing, superfinishing for very low roughness.

Chemical treatment:

Sealing to close micro‑porosity - critical for hydraulic/pneumatic sealing, corrosion protection, electrical insulation, friction control (e.g., PTFE sealers) and visual/architectural finishes.
Painting recommendations, including the importance of swift application over Zn/Al coatings (referenced EN ISO 2063 and EN ISO 12944‑5).
Chemical conversion and color treatment for visual/aesthetic purposes.

Thermal treatment:

Fusing of self‑fluxing alloys (see EN ISO 14920), diffusion annealing to improve bond strength (requires controlled atmosphere or vacuum), and hot isostatic pressing to increase density and adhesion.

Health & safety: Follow applicable protective, labour and environmental guidelines for each process.

Practical applications and users

Intended for: coating engineers, surface treatment specialists, manufacturing engineers, maintenance teams, OEMs, quality managers and specifiers.

Typical uses: restoring worn machine components, creating corrosion‑resistant surfaces, producing functional seals, improving tribological properties, and preparing components for final machining or painting.

Benefits: helps select appropriate finishing methods, tooling and process controls to avoid coating damage, contamination or premature failure.
