DC for metal and other inorganic coating engineering Measurement of Adhesion of Magnetron Sputtering Silver Coatings Warning---The use of this document may involve harmful materials, dangerous operating procedures and equipment. Before use, it is the responsibility of the user of this document to establish appropriate safety and health practices and determine their compatibility with the Adaptability of relevant laws. 1 Scope This document describes the adhesion test method for DC magnetron sputtered silver coatings for electrical, electronic, optical and other engineering applications. This document applies to the measurement of the adhesion of DC magnetron sputtered silver coatings on sheet materials and flat objects. This document is not applicable to the measurement of the adhesion of DC magnetron sputtered silver coatings on threads, strips or wires. This document does not specify the condition and surface roughness of the substrate material prior to deposition. Therefore, it is the purchaser's responsibility to specify the surface roughness of the substrate. to meet product requirements. 2 Normative references The contents of the following documents constitute essential clauses of this document through normative references in this document. For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to This document. GB/T 3138 Terminology for surface treatment of metals and other inorganic coatings (GB/T 3138-2015, ISO 2080.2008, IDT) GB/T 5270 Review of the test method for adhesion strength of electrodeposited and chemically deposited metal coatings on metal substrates (GB/T 5270-2024,ISO 2819.2017, MOD) GB/T 12334 Definitions and general rules for thickness measurement of metals and other non-organic coatings (GB/T 12334- 2001,ISO 2064.1996,IDT) 3 Terms and definitions The terms and definitions defined in GB/T 3138, GB/T 12334 and the following apply to this document. 3.1 Sputtering The process in which high-speed ions bombard the target material to produce particles, which can cause the target metal material particles to be deposited on the surface of the substrate. 3.2 Adhesion The interface force between the coating and the substrate is composed of atomic bonding force, mechanical bonding force or both. 4 Adhesion test method 4.1 Friction and polishing test Use an agate knife with a diameter of 6 mm and a smooth hemispherical end as a friction polishing tool, and choose an effective surface area of no more than 6 cm2 ...... |
