The paper describes the existing directions and features in the field of non-destructive testing of thermosetting plastic products, in particular, brake pads of freight cars. The article presents defects that lead to a decrease in the declared resource of wheelsets as a result of interaction with the brake pad during operation. The process of enveloping metal is described. Describes production data provided by railcar repair companies, accompanied by illustrative material. Analyzed are methods of non-destructive testing, the use of which will reduce the damage to wheelsets, by selective testing of brake pads from each batch supplied to a repair facility or plant. Conclusions and tasks for further research are formed.

In this scientific work, the authors consider the issue of non-destructive testing. In the article, the authors describe the process of improving the performance properties of polymeric products of complex configuration. In the article, the authors choose the method of high-frequency control as the most suitable for assessing the quality of products in the manufacture and during repair work. The scientific work describes the process of diagnosing products made from polymeric materials on the developed diagnostic device. This article describes the development of methods for designing a technological additional device for diagnosing products of complex configuration. In this paper, the authors solved the problem of manufacturing electrodes for experimental diagnostics. The authors drew conclusions and set goals for further research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
