“…The CPP test is an adhesive-free method comprising a 'pin' and a 'collar' assembled with two grub screws. The original idea of the CPP test was taken from the designs published in [22,23], which was further modified/improved for easy integration with ASTM C633 [18] test fixtures. The specimen preparation process and the schematic of the CPP test set-up are shown in Figure 3, further details of the test method can be found in [1].…”

This study aims at investigating the effect of post-deposition solution treatment and ageing (STA) on improving the interfacial adhesion strength in cold spray (CS) Ti6Al4V coatings deposited on Ti6Al4V substrates, measured by the adhesive-free collar-pin pull-off (CPP) test. Solution treatment was performed at 940 °C for 1 h and ageing was carried out at 480 °C for 8 h. Investigations were carried out for specimens with three different pre-treatments of the substrate surface, namely grit-blasted, as-machined (faced on lathe machine), and ground. Additionally, the effect of post-deposition STA was studied in terms of phase analysis, microstructure, and porosity level. It was observed that STA led to complete interfacial mixing resulting in significantly improved adhesion strength (by more than 520%) with the maximum measured value of greater than 766 MPa for ground substrates, reaching 81% of the ultimate tensile strength of mill annealed Ti6Al4V.

“…When using cylindrical pins, the clearance between the pin and the matrix is at stake, as when the coating is laid on, its fractions being put into the clearance, result in welding of the pin with matrix, thus garbling the true value of the adhesive strength. In order to lower the effect of the friction between the pin and the matrix and, in the same time, to minimize the clearance between said details, the cylindrical pins have been changed to conical (Picture.1) [5,6,7,9] .…”

In this article the various methods of assessment of gas-thermal coating’s adhesion strength are considered. The methodology of carrying out the strength tests, using traditional methods of quantitative assessment of adhesive strength of a coating towards its basement, is reflected; the advantages and disadvantages of the represented methods are given. In the article, the theoretical justification of the mechanics of adhesive avulsion is given, and the imperfection of conic pins’ usage is shown. Aiming at increasing of the accuracy and quality of the strength tests of gas-thermal coatings, a modernised methodology, as well as the samples (а.с.1436025), related to detection of the adhesion strength, are suggested. The theoretical computation of the reasonableness of usage of ring cross section of the coating, resulted in the event of usage of the offered sample, is given. On the basis of theoretical computation, a defining formula of the adhesive strength is conducted. Comparison tests of adhesion strength with various sample’s designs are completed. The reasonableness and effectiveness of usage of the offered methodology in assessment of gas-thermal coating’s adhesion strength are proven.
