Introduction

1. Background and significance of the standard

GB/T 36591-2018 "Metallographic Test Method for Coatings of Cemented Carbide Products" is a key standard for quality control of cemented carbide coatings. This standard is based on the internationally accepted metallographic technology and is formulated in combination with the characteristics of China's cemented carbide industry. It aims to unify coating detection methods and improve product quality and reliability.

2. Comparison of standard frameworks

Standard dimensions	Technical requirements	Application examples
Detection scope	Applicable to metallographic inspection of coatings on cemented carbide products	Including coating quality assessment of workpieces such as tools and molds
Instruments and equipment	Metallographic microscopes with magnification of 1000 times or above, Rockwell hardness testers	Common equipment includes Zeiss metallographic microscopes and Rockwell HR-150 Rockwell hardness testers
Detection indicators	Coating thickness, porosity, white phase level, etc.	Such as coating thickness measurement, peeling degree assessment

3. Implementation suggestions

3.1 Inspection personnel training

Inspectors need to undergo professional training and master the skills of using metallographic microscopes and standard grading requirements.

3.2 Equipment maintenance and calibration

Metrological calibration of metallographic microscopes and Rockwell hardness testers should be performed regularly to ensure measurement accuracy.

3.3 Data recording and analysis

Establish a complete inspection record database to facilitate quality traceability and process optimization.
