Introduction

Core changes and scope of application of the new standard

GB/T23520-2022 is the authoritative specification for platinum composite anode plates, covering the full process technical requirements for composite materials such as Pt/Nb, Pt/Nb/Pt, and Pt/Ti. Compared with the 2009 version, 6 new characteristic modifications are added:

Comparison dimensions	2009 version	2022 version
Applicable fields	Special for ships	General protection
Material grades	2 types of substrates	Newly added TA2 titanium substrate
Inspection accuracy	±0.2mm	Deviation classification control

Detailed explanation of key technical specifications

Comparative analysis of material composition

Substrate type	Platinum layer purity	Niobium-based chemical indicators
Nb(TNb1)	≥99.95% SM-Pt	Nb+Ta≥99.95%
TA2 titanium	Double-sided composite structure	Impure Fe≤0.30%

Mechanical performance requirement parameters

The precision grading system is significantly optimized, and three-level control is set for key dimensional parameters:

Total thickness fluctuation: -0.10mm~-0.60mm (divided into three levels)
Lower limit of platinum layer thickness: 0.010mm (break point loss level)

Key test methods and implementation points

Combination strength test case: Using 20T manual hydraulic press to apply pressure deformation test, the platinum deformation part needs to maintain the synchronous buckling of the base metal.
Key points of detection: visually no delamination and macroscopic size combination verification.
