Aerospace series - Adhesion test for metallic coatings by shot peening

This standard specifies a test method to determine the adhesion of coatings by shot peening. It applies to ductile metal coatings, such as cadmium, silver or copper, with a hardness: - inf to 250 HV for a coating thickness between 25 and 250 micro m ; - sup or equal to 250 HV for a coating thickness between 10 and 60 micro m. It shall be applicable whenever referenced.

Overview

EN 2829:1994 (CEN) specifies a standardized test method to determine the adhesion of metallic coatings by shot peening. The method is intended for ductile metal coatings - for example, cadmium, silver and copper - and defines applicability by coating hardness and thickness. The standard is applicable whenever it is referenced in procurement or quality documentation and has been adopted nationally (e.g., SIST EN 2829:2001).

Key applicability details from the scope:

  • Coating materials: ductile metallic coatings such as cadmium, silver, copper
  • Hardness / thickness ranges:
    • coatings with hardness up to 250 HV: thickness between 25 µm and 250 µm
    • coatings with hardness ≥ 250 HV: thickness between 10 µm and 60 µm

EN 2829:1994 focuses on providing reproducible criteria for assessing whether a coating remains adherent after controlled mechanical impact by shot peening, supporting consistent acceptance and rejection decisions in aerospace manufacturing and maintenance.

Key Topics

  • Shot peening adhesion test: A mechanical impact-based assessment that evaluates coating adherence under controlled shot-peening conditions.
  • Material scope: Targets ductile metallic coatings (cadmium, silver, copper) within specified hardness and thickness limits.
  • Quality criteria: Establishes when shot-peening results indicate acceptable adhesion for continued service or when remedial action is required.
  • Standard adoption: Recognized by CEN and incorporated in national standards (SIST EN 2829:2001 for Slovenia).

Applications

EN 2829:1994 is primarily used in the aerospace sector where metallic coatings protect components against corrosion, wear or provide other functional properties. Practical applications include:

  • Acceptance testing for coated aerospace components during manufacturing
  • Inspection protocols during maintenance, repair and overhaul (MRO)
  • Quality control checks for coating suppliers and plating shops
  • Supporting procurement specifications to ensure coatings meet adhesion expectations

Benefits of using this standard:

  • Consistent, repeatable adhesion assessments across suppliers and maintenance facilities
  • Clear applicability boundaries by coating hardness and thickness
  • Improved confidence in coating performance and component reliability

Related Standards

  • CEN EN 2829:1994 is the primary reference for shot-peening adhesion testing of ductile metallic coatings. National adoptions include SIST EN 2829:2001.
  • For complete coating specifications and complementary test methods, users should reference other CEN/EN aerospace coating and testing standards and applicable national aerospace material specifications.

For procurement, inspection planning and supplier agreements, reference EN 2829:1994 to ensure adhesion testing using shot peening is applied consistently where specified.
