Title:
GAP BASE MATERIAL FOR REDUCING FRETTING WEAR, AND FASTENING STRUCTURE USING GAP BASE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2009/050914
Kind Code:
A1
Abstract:
A gap base material for reducing fretting wear (micromotion wear) and a fastening
structure using the gap base material. The gap base material (1) having faces
(2, 2) sandwiched between the contact faces (7) of contact materials (6) that
generates friction and wear and embodying slide or vibration of the gap base material
(1), is characterized in that the faces (2, 2) embodying sliding or vibration
of the gap base material (1) have a higher hardness as compared with at least one
contact face (7) of the first contact material (6) and the second contact material
(6'), and the faces (2, 2) embodying sliding or vibration of the gap base
material (1) have a lower coefficient of friction and a higher smoothness as compared
with at least one contact face (7) of the first contact material (6) and the second
contact material (6'), and thereby the faces (2, 2) embodying sliding or
vibration of the gap base material (1) make the contact face (7) of the contact
material (6) difficult to wear.
