MODEL TO DETERMINE cohesive strength of thermal spray powder coating

摘要

The technical solution relates to the field of test engineering and allows to extend the functionality of the sample to determine the bond strength of adhesion and mechanical properties of the study. The test specimen on the cohesive strength of thermal spray powder coatings has two installed butt cylinders on the area joint outer surfaces are coated with a covering ring, a central stud with the abutment members, the cylinders are made of the conjugated to enable pressing the junction of the abutment members in the form of nuts , wherein the outer surface is stepped cylinders with different diameters, the central stud with the abutment elements is formed as a mandrel, SET lennye butt cylinders conjugate conical end surfaces at an angle of 75 °, wherein the end of one cylinder is formed with a conical recess, and the other with a conical protrusion on the outer surfaces of cylinders with different diameters additionally installed filters restricting zone coating, which is made of self-fluxing material and epoxy resin layer thickness equal to the wall thickness of the protective screens. The technical result is improvement in quality of preparation of the substrate surface, reducing the complexity and allowing multiple use sample. 4 yl.
