Абстракт: Докладът разглежда микроструктурата и износоустойчивостта на слоеве, получени чрез нанасяне на смес от прахообразен материал и свързващо вещество върху образци и последващото им сканиране с плазмена дъга. Описана е подготовка на образците за нанасяне на покритието и изследване на степента на износване. Анализирана е получената микроструктура на слоя и са направени изпитвания за определяне на износоустойчивостта срещу абразивно триене.

Abstract: The report is devoted to the study of the microstructure and wear properties of layers obtained by applying a mixture of powder and a binder on a sample and subsequent scanning of the working surface with plasma transferred arc to melt lead paint and partial melting of the substrate. The preparation technology of samples prior to scanning and abrasive wear testing is described. The microstructure and abrasive wear behavior of the layers is analyzed and the resistance against abrasive wear is determined.
