Scope

1.1 This test method covers the determination of abrasive wear resistance of cemented carbides.

1.2 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents of inch-pound units are in parentheses and may be approximate.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

This test method provides a guide to determine the relative abrasive wear resistance of cemented carbides under high-stress abrasion conditions. The abrasive wear is not a measure of wear characteristics of carbides under all conditions and is not to be misconstrued as indicative of wear when carbides are used for machinery. It does show the difference in resistance to abrasive use for different carbide compositions and can be used as a practical test or as a research method for sorting out these differences.
