GB/T 10430-2008Inspection method for bonding ability of sintered friction elements (English PDF)

Foreword

This standard replaces GB/T 10430-1989 "sintered metal friction plate bonding strength determination." This standard GB/T 10430-1989 amended as follows.

--- Standard Chinese original title was changed to "sintered metal friction plate bonding performance test method" and the English title revised accordingly.

--- Modify the original standard test apparatus.

--- Modify the original standard sample requirements.

--- Modify the original standard test results evaluation method.

--- Provisions of the specification referenced file version.

--- Using the latest standard narrative language.

1 Scope

This standard specifies the test device performance test bonding sintered metal friction plate friction material and steel core plate, sample, test procedures and test Inspection reports.

This standard applies to the manufacture of sintered powder metallurgy friction plate, bending test method for testing the inter-friction material layer and the bonding properties of the steel core plate, Other similar materials may also be implemented by reference.

2 Test device

V-groove test apparatus is shown in Figure 1.

1 --- press on the platform;

2 --- indenter (tip R = 10mm, width L = 50mm);

3 --- steel core plate;

4 --- friction material layer;

5 --- V-groove (thickness 60mm; 45 # steel, quenched and tempered hardness of 28HRC ~ 33HRC);

6 --- press the lower platform.

3 Sample

3.1 specimen directly with the test product can be cut from the tested product, the size of the sample width not more than 50mm, the sample length is not less than 70mm, and to ensure that does not affect the accuracy of test results.

3.2 per furnace batch friction plate number of samples by the user and manufacturer of consultations among themselves.
