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.

Strength Tests

The adhesive strength of the metal cord, i. e. the strength of its adhesion to the compound, is one of the most important indicators of the quality of the metal cord. Increasing the amount of adhesive strength allow to improve the performance of finished tires.Determination of the adhesive strength value can be performed by different methods. All methods are based on extracting (pulling) metal cord from a block of vulcanized rubber and fixing the required load. Each method has its own characteristics that affect the amount of adhesive strength. Therefore, when conducting comparative tests, it is necessary to use one of the selected methods.The study of factors that affect the amount of adhesive strength is necessary to identify the causes that lead to its change.The article analyzes how the quality of the used compound affects the adhesive strength. Tests with the use of compounds with various defects were considered and carried out; probable factors leading to deviations in the adhesion strength indicators were determined.

Strength Tests

In this study, efficient, high-precision grinding of cemented carbide alloys using a specific grinding wheel was performed, and the ground surface characteristics were investigated in detail. The results showed that final finishing using a chromium-bonded wheel produced an extremely smooth surface with an average roughness Ra of 4 nm. The grinding process produced a chromium- and copper-rich surface layer, as well as a large amount of diffusion of oxygen. Adhesive strength tests using a microscratching method were also carried out on ground substrates coated with diamond-like carbon (DLC) films. The surface ground by the chromium-bonded wheel exhibited superior adhesive strength due to its strong chemical affinity with the DLC film.

Tooth Tissue

Restoration of decayed teeth with tooth-colored materials that can be bonded to tooth tissue has been a highly desirable property in restorative dentistry for many years. Advantages of such an adhesive restorative technique over conventional techniques using non-adhesive metal-based restoratives include improved restoration retention with minimal sacrifice of sound tooth tissue for retention purposes, superior adaptation and sealing of the restoration margins in prevention of caries recurrence, improved stress distribution across the tooth-restoration interface throughout the whole tooth, and even reinforcement of weakened tooth structures. The dental adhesive technology is rapidly changing. An efficient resin bond to enamel has already long been achieved. Its bonding mechanism has been fully elucidated and has proven to be a durable and reliable clinical treatment. However, bonding to dentin represents a greater challenge. After the failures of a dentin acid-etch technique in imitation of the enamel phosphoric-acid-etch technique and a bonding procedure based on chemical adhesion, modern dentin adhesives are currently believed to bond to dentin by a micromechanical hybridization process. This process is developed by an initial demineralization of the dentin surface layer with acid etchants exposing a collagen fibril arrangement with interfibrillar microporosities that subsequently become impregnated by low-viscosity monomers. Although the development of such a hybridization process has well been documented in the literature, questions remain with respect to parameters of-primary importance to adhesive efficacy.
