Описание (английский):

ISO 2819:2017 specifies methods of checking the adhesion of electrodeposited and chemically deposited coatings. It is limited to tests of a qualitative nature. ISO 2819:2017 does not describe certain tests that have been developed at various times to give a quantitative measure of adhesion of metallic coating to a substrate, since such tests require special apparatus and considerable skill in their performance which renders them unsuitable as quality control tests for production parts. Some of these quantitative tests can, however, be useful in research and development work.

Abstract

Overview

ISO 2819:2017 - "Metallic coatings on metallic substrates - Electrodeposited and chemically deposited coatings - Review of methods available for testing adhesion" provides a consolidated review of qualitative adhesion tests for metallic electroplated and chemically deposited coatings. The standard lists common, practical methods used to check whether a metallic coating is properly bonded to its metallic substrate. It does not prescribe quantitative laboratory techniques that require special apparatus; those are noted as more appropriate for research and development rather than routine quality control.

Key Topics

Scope and purpose: Focus on qualitative adhesion checks for electrodeposited and chemically deposited coatings; excludes complex quantitative tests unsuitable for production QC.
Test methods reviewed (Section 4): burnishing, ball burnishing, shot peening (including Annex A for silver deposits 100–600 µm), peel (including tape test), file, grinding and sawing, chisel, scribe and grid (cross-hatch), bending, twisting/winding, tensile (including centrifugal adhesion extension), thermal shock, drawing, cathodic tests, Rockwell‑C, scratch, and cavitation.
Practical limits: e.g., peel test suitability for coatings
