Determination of transverse rupture strength of sintered metal friction materialsDetermination of apparent hardness of sintered metal friction materialsTest bench test method for friction performance of wet sintered metal friction materialsTest method for friction performance of wet sintered metal friction materialsTest method for friction performance of dry sintered metal friction materialsThe average value of the instantaneous dynamic friction coefficient of the friction pair during the joining process. 3.2 Static friction coefficient
The ratio of the maximum friction force generated on the contact surface of the friction pair to the normal force under static friction state. In actual tests, the static friction coefficient is the ratio of the friction force generated on the contact surface to the normal force when the active part of the friction pair slowly slides relative to the driven part under the action of external force. 3.3 Wear rate
Volume wear per unit friction work under specified test conditions, cm/J. 4 Material classification
4.1 Materials are divided into iron-based and copper-based according to the composition of the matrix, and are divided into dry and wet types according to the working conditions. 4.2 Method of indicating grades
