EN 2536:1995 - Aerospace series - Hard anodizing of aluminium alloys

Overview

EN 2536:1995 (adopted as SIST EN 2536:2001) is a CEN aerospace series standard that specifies requirements for hard anodizing of aluminium alloys used in aerospace construction. The standard sets out the scope, process control, quality characteristics and acceptance criteria for hard anodic oxide coatings on aluminium parts and is intended to be applied wherever referenced in procurement or design documentation.

Key topics and requirements

The standard addresses the technical and quality aspects of hard anodizing without prescribing proprietary process recipes. Key topics typically covered include:

  • Scope and applicability - definition of parts and aluminium alloys suitable for hard anodizing in aerospace use and statement that the standard applies when referenced.
  • Surface preparation - general requirements for cleaning, degreasing and pre-treatment to ensure consistent anodic coating performance.
  • Process control - expectations for controlled anodizing processes, including bath management, monitoring and traceability of process parameters.
  • Coating characteristics - required functional properties such as enhanced wear resistance, improved corrosion protection and specific surface finishes appropriate for aerospace service.
  • Inspection and testing - acceptance criteria and nondestructive/destructive inspection methods to verify coating uniformity, adhesion and integrity.
  • Documentation and traceability - requirements for records, part identification and supplier certification to support quality assurance and compliance.

Note: EN 2536 provides regulatory and procurement guidance rather than prescribing exact bath compositions, voltages or thicknesses; those details are determined by the customer specification or referenced process documents.

Applications and users

EN 2536 is relevant for anyone involved in the production, specification or procurement of anodized aluminium components for the aerospace industry:

  • Aerospace manufacturers and OEMs specifying surface treatments for airframes, structural parts and components requiring hard anodic protection.
  • Surface treatment and heat-treatment shops implementing hard anodizing services to meet aerospace quality and traceability demands.
  • Quality assurance and inspection teams establishing acceptance criteria and test plans for anodized parts.
  • Procurement and supply chain professionals ensuring supplier compliance with aerospace coating standards.

Practical applications include improving wear resistance, extending service life, providing electrical insulation and improving corrosion protection of aluminium alloy components used in aviation and space systems.

Related standards

EN 2536 is part of the broader family of aerospace coatings and surface-treatment standards and should be used alongside applicable aluminium alloy specifications, quality-system requirements and any customer-specific process documents when defining anodizing requirements. Keywords: EN 2536, hard anodizing, aluminium alloys, aerospace, anodic oxidation, surface treatment, coatings.
