A METHOD FOR PROVIDING A FRICTION MEMBER, A FRICTION MEMBER AND AN ASSEMBLY WITH A FRICTION MEMBER

摘要

A steel or iron friction member (50) is provided with a predetermined exact thickness for creating high resistance to shear movement when said friction member (50) is squeezed between two mating metallic surfaces (30,32,44,46) of at least two machine parts (20,40) by at least two clamping devices (42) per friction element (50). For providing the squeeze force the friction member (50) is provided with at least one friction face (47) to mate with a mating face (30,32,44,46) of one of said machine parts, The method involves roughening said friction face (47) followed by non-depositing surface hardening the roughened friction face (47).
