Determination of hardness of thin layer coating and its adhesion to the shell of the cylindrical form

On the basis of coatings a lot of technical and economic problems are solved. Functional and smart coatings are developed, which are formed directly on the curvilinear surfaces of structural elements. An experimental-theoretical method for evaluating the stiffness properties and adhesion of a thin-layer coating of a complex structure formed on a cylindrical surface is developed. The method is a reliable tool both for determining the mechanical properties of a coating and an adhesive, and for studying the effect of physical fields and media on changing these properties. An example of a study is considered.
