Title:
腐食疲労試験における引張り試験で要求される鋼の異形試験片を入手するための方法および装置
Document Type and Number:
Japanese Patent JP2004511770
Kind Code:
A
Abstract:
A method is described to prepare shaped steal test-pieces (1) for tensile under corrosion fatigue tests, which provides for contacting a test-piece (1) subject to rotation about its longitudinal axis and, each time, a disk (10) of sand paper, also rotating, the contact being ensured by the own weight of the test-pieces itself. A device for carrying out this method is also described, which comprises a swinging arm (2) at an end of which the test-piece (1) is rotatably mounted, being driven by a motor (5), all these being mounted on a support central table (6), substantially stationary, around which a support (7) can rotate, having an annular shape on which a number of abrasive disks (10) are mounted, each on a rotatable shaft (9), to be successively positioned at the processing station in front of said supporting arm (2).
