Introduction of GB/T 43602-2023

GB/T 43602-2023 Composition, structure and properties of PVD multi-layer hard coatings 1 Scope This document specifies the evaluation standard of the composition, structure and properties ofmulti-laver hard coatings by common physical vapor deposition (PVD). This document applies to coating materials prepared using vacuum deposition methods such as evaporation, sputtering, or related non chemical methods. 2 Normative references The following documents are referred to in the text in such a way that some or all of their contenconstitutes requirements of this document, For dated references, only the edition cited applies. Forundated references, the latest edition of the referenced document including any amendments applies. ISO 4545-1 Metallic materials- Knoop hardness test - Part 1: Test method ISO 6507-1 Metallic materials - Vickers hardness test - Part 1: Test method ISO 9220 Metallic coatings - Measurement ofcoating thickness - Scanning electron microscope method ISO 14577-1 Metallic materials - Instrumented indentation test for hardness and materials parametersPart 1: Test method ISO 20808 Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination offrictionand wear characteristics ofmonolithic ceramics by ball-on-disc method ISO 26423 Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination ofcoatingthickness by crater-grinding method 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and lEC maintain terminological databases for use in standardization at the following addresses: ——ISO Online browsing platform: available at https://www.iso.org/obp ——IEC Electropedia: available at http://www.electropedia.org/ 4 Samples for composition, structure and properties evaluation Samples for the composition, structure and properties evaluation should be coated in the same batchas the products requiring the composition, structure and properties evaluation, The samples should bepolished to a mirror finish (Rpk < 0,05 μm) before being coated and cleaned using ultrasonic agitationwhich immerses them in the correct solution to remove hydrocarbons and other surface contaminants.
