DEVICES AND METHODS FOR CONDUCTING ACCELERATED AGING TESTS OF A COATING WITH SEVERAL TYPES OF STRESSES

摘要

A device for conducting accelerated aging tests of a coating, notably an outer coating for an aircraft, in particular allowing the testing of the durability of the coating after having been subject to all kinds of stresses, is desired. An object of the disclosure thus relates to such a device including test chambers subject to different and/or independently controllable test parameters, and including light for generating photo-oxidation, the device including a support for a sample of the coating, displaceable between the chambers for generating mechanical stresses by thermal shocks. The disclosure herein finds applications in many fields of industry, and preferentially in the field of aeronautics.

主权项

1. A device for conducting accelerated aging tests of a coating, the device comprising at least a first test chamber and a second test chamber which are separated by a mobile partition, each chamber being subjected to accelerated aging test parameters, comprising at least temperature and level of humidity, the test parameters being different from the first and second chambers and/or controllable independently from the first and second chambers, each of the first and second chambers additionally comprising a light to generate photo-oxidation, and the device also comprising a support for retention of at least one sample of the coating, the support being displaceable from the first chamber to the second chamber and conversely, after opening of the mobile partition between the first and second chambers in order to generate mechanical stresses by thermal shocks.
