Metal Products

At present, many kinds of metal products are produced with application of various coatings. Coatings along with requirements to provide their functional properties, must also meet additional general requirements, in particular, must have a high adhesion resistivity. Methods of direct measuring of adhesion characteristics considered. It was shown, that estimation of coatings adhesion properties by regular standard methods has a subjective character, since it is accomplished visually by specially trained laboratory assistants. Appearance of new standards and modern devices for determining of adhesion characteristics of different coatings by scratch test creates new possibilities of those properties regulation in digital form without subjective estimations. A methodology considered for determining coatings adhesion properties by application theory of scratch test. Estimation of strength parameters of the coating material depending on coating destruction character by power and geometric parameters of the deformation hearth was carried out. The relation of power characteristics of deformation hearth under indenter analyzed. Advantages and drawbacks of the scratch test quoted. It was noted, that implementation of new devices for the scratch test has required adoption of new standards for polymer and ceramic coatings. Implementation of those standards and devices for estimation of different coatings adhesion properties by application scratch test at present has no insuperable obstacles.

Modulus of elasticity of steel wire rope (elastic modulus) is a characteristic value, which is important not only for users of the steel rope, but also for designers of machines and machinery that are equipped with the steel wire rope. Values of the elastic modulus depends predominately on the elastic modulus of the material, which the rope is manufactured from as well as it depends on the various other factors. The most important influencing factors are as follows: rope construction, type of core, angle and way of wire stranding, angle and way of rope lay as well as kind of lubricant. The real value of the elastic modulus has also impact on prolongation of the steel wire rope and on intensity of its dynamical loading. The rope elastic modulus value can be determined by means of the various methods. There are analysed in this article such methods for determination of the rope elastic modulus, which can be applied for a computer simulation.
