Machine and method of testing tribolu00d3gico for the determination of the coefficient of friction in contact with the surface recu00c9m interfaces generated no oxidized

摘要

The present invention relates to a method and corresponding apparatus for determination of the coefficient of friction at the contact interfaces where there are areas recu00c9m generated, yet not oxidized, cleaned and chemically active.This invention is especially suited for applications where it is to evaluate the influence of areas recu00c9m generated on the oxidized, as a typical case of its application to determine the friction coefficient in the process tecnolu00d4gicos cutting by stock removing.The test machine tribolu00d3gico comprises a table which supports the whole structure (6),Which is the engine with variable frequency (13) for the precise control of speed of rotation of the disc (5); and a support on which is mounted a two-dimensional load sensor (9) and the system of location of specimen in the form of a pin (12) which is mounted on a support (4) deslizant And on a guide (8) and its movement is controlled by a motor (1); a system of purchase.Control and monitoring of data which in turn is connected to a personal computer.
