SPECIMEN FOR INVESTIGATING THE PROPERTIES OF COATING MATERIALS

摘要

The invention relates to mechanical engineering, in particular to study m mechanical properties of coating materials. The aim of the invention is to expand the functional capabilities of the sample to investigate the properties of the coating materials, improved accuracy and material savings by allowing determination in the same sample not only cohesive, but also the coating adhesion strength as well as its durability. This object is provided by the fact that the sample formed from two established butt same diameter cylinders and coating them with a covering both cylinders ring comprises on either side of the plane of the junction cylinders working slice area and friction at the free end of the cut zone an annular abutment spaces intended for applying the coating in determining shear adhesion strength of the coating to the material of the second cylinder. 5 yl. with a
