Mechanical Conditions in Bulk Metal Forming Tribometers - Part Two

Groche, Peter and Stahlmann, Jörg and Müller, Christoph (PtU) (2013):
Mechanical Conditions in Bulk Metal Forming Tribometers - Part Two.
In: Tribology International, pp. 345-351, 66, [Article]

Abstract

Processes of bulk metal forming are highly influenced by the tribological conditions. Therefore, the tribological systems have to bear high tribological loads and special test stands are necessary to investigate their behavior. However, most common test stands are not able to sufficiently achieve the loads. This paper presents a new approach, the Sliding Compression Test, which allows examining all tribological loads and has a high homogeneity, usability and flexibility. For this test stand, a face and barrel setup of the specimen is possible. Examinations indicate that the different deformation sequences of the setups cause considerably different friction coefficients. It is assumed, that the amount of lubricant affects the friction coefficient. This is determined by the history of contact.
