Overview

EN 2830:1993 is a CEN standard focusing on the adhesion testing of metallic coatings used predominantly in the aerospace industry. This standard specifies a precise test method to determine the adhesion quality of metallic coatings by shearing action. It is essential for ensuring the reliability and durability of metallic coatings applied to aerospace components, which often require strict performance criteria to maintain safety and functionality.

The standard covers coatings with different hardness and thickness ranges:

• Coatings with hardness less than 250 HV and thickness greater than 75 micrometres.
• Coatings with hardness between 250 HV and less than 700 HV and thickness greater than or equal to 15 micrometres.

EN 2830:1993 is applicable whenever referenced within aerospace manufacturing and quality assurance processes, supporting enhanced coating performance evaluation.

Key Topics

• Adhesion Test by Shearing Action: The core focus is the determination of how well metallic coatings adhere to their substrates when subjected to shear forces.
• Coating Hardness and Thickness: Test applicability depends on the coating’s Vickers hardness (HV) and thickness parameters, ensuring appropriate test application according to material characteristics.
• Aerospace Industry Relevance: Designed specifically for coatings used in aerospace and related industries, addressing strict operational requirements.
• Standardized Procedure: Ensures consistent, repeatable testing results across different laboratories and manufacturing environments.
• Compliance and Quality Control: Supports manufacturers in maintaining the quality and adherence of metallic coatings, which contribute to component longevity and performance.

Applications

• Aerospace Component Coatings: Utilized for testing metallic coatings applied to aircraft and spacecraft components, where high reliability is critical.
• Quality Assurance in Manufacturing: Incorporated into inspection routines to verify coating adhesion quality before components proceed to assembly or service.
• Research and Development: Used by material scientists and engineers to evaluate new coating materials and processes for aerospace applications.
• Failure Analysis: Helps in identifying coating adhesion issues that may lead to premature failure in service conditions.
• Supplier Verification: Enables aerospace manufacturers to verify that supplied coatings meet required adhesion standards.

Related Standards

For comprehensive aerospace coating quality assessment, EN 2830:1993 can be used in conjunction with other standards, including:

• EN 12279 - for testing corrosion resistance of coatings.
