    New Test Method for Galling Resistance of Non-lubricated Material Couples

    (What is a Work Item?)

    Developed by Subcommittee: G02.40 | Committee G02 | Contact Staff Manager


    1. Scope

    1.Scope 1.1.This test method covers a laboratory test that demines the galling resistance of material couples using a quantitative measure. 1.2.Bare metals, alloys, non-metallic materials, coatings, and surface modified materials may be evaluated by this test method. 1.3.This test method is not designed for evaluating the galling resistance of material couples sliding under lubricated conditions because galling usually will not occur under lubricated sliding conditions using this test method. 1.4.The values stated in SI units are to be regarded as standard. Inch-pound units of measurement are shown in some cases for information only. 1.5.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.

    At the December 2011 G02 Committee meeting in New Orleans the results of the G98 ILS (round robin) were presented. They showed that the reproducibility of the G98 method to be +/- 76%. With this poor reproducibility in mind, the committee asked me to develop a new galling test method to replace G98. A new method has been developed that has the following key elements: Easily manufactured specimens Same specimens as G196 galling test Test can be conducted using a universal test machine capable of constant force Simple test procedure
