<p>The invention relates to a method for testing the coating (36) of a vane base that comprises: providing a so-called disc specimen (22) including at least one bearing surface, and another so-called vane specimen (32) including at least one bearing surface (34) covered with said coating and comprising two semi-specimens (32) which can be inserted on either side of the disc specimen; subjecting the vane specimen (32) inserted with the disc specimen (22) to pulling cycles during which a specimen is pulled relative to the other, the pulling force being transmitted via the contacted bearing surfaces of the vane specimen and of the disc specimen. The method can be used for a very reliable reproduction of the coating behaviour and ageing, and thus enable an accurate evaluation of the quality of coatings.</p>
