Scope

GB/T 45880-2025 is the English-translated version of 单片陶瓷摩擦和磨损特性的测定球板法.

GB/T 45880-2025 is the Chinese national method for measuring how a monolithic ceramic rubs and wears, by sliding a ball against a disc of the material in dry, non-abrasive conditions.

It yields two results, the coefficient of friction and the specific wear rate, and fixes the specimens with their surface texture and geometric tolerances to GB/T 3505 and GB/T 1182, the contact stylus profilometer to GB/T 6062, the test conditions, the calculation and the report, with laboratory competence to GB/T 27025.

It applies to fine ceramics tested as a pair of materials in contact. Ceramic producers and tribology laboratories use it to compare materials for sliding contact.

Modified from ISO 20808:2016, it was issued on 30 June 2025 and has applied since 1 January 2026.

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is modified to adopt ISO 20808:2016 "Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination of the Friction and Wear Characteristics of.

The technical differences between this document and ISO 20808:2016 and their reasons are as follows.

--- Replaced ISO 1101 with the normative reference GB/T 1182 to improve operability (see 5.3, ISO 20808:2016 5.3);

--- Replaced ISO 4287 with the normative reference GB/T 3505 to improve operability (see 5.2, 5.3, ISO 20808:2016 5.2, 5.3);

--- Replaced ISO 3274 with the normative reference GB/T 6062 to improve operability (see 6.6, ISO 20808:2016 6.6);

--- Replaced ISO /IEC 17025 with the normative reference GB/T 27025 to improve operability (see Chapter 9, ISO 20808:2016, Chapter 9). The following editorial changes have been made to this document.

--- To coordinate with the existing standard, the name of the standard is changed to "Determination of friction and wear characteristics of monolithic ceramics - Ball-plate method".

1 Scope

This document specifies the procedure for determining the coefficient of friction and specific wear rate of monolithic ceramics. In this method, the material is placed in a ball-on-disk apparatus and The measurements were carried out in pairs in a dry, non-abrasive environment.

This document applies to the determination of friction and wear properties of fine ceramics.
