METHODS OF MANUFACTURING CAST DETAILS WITH A SOLID-ALLOY COATING AND HEAT TREATMENT

The article discusses the innovative technology of manufacturing molded machine parts and equipment with a wear-resistant carbide coating by casting on gasified models. The methods of applying wear-resistant coatings on the working surface of cast parts are given. Methods for determining the hardness and abrasive wear resistance of cast steel samples and parts after optimal heat treatment with double phase recrystallization, which increase the wear resistance of parts by 3-4 times, have been studied.
