On the Issue of Casting Copper Alloys in Chill Mold

Abstract

The article describes the features of the process of casting copper alloys in the chill mold. The main properties of alloys depending on the content of various components in it are revealed. The main negative factors leading to a decrease in the casting properties of the process, as well as the quality of the castings obtained, are indicated. Based on the information and analytical review, possible options for improving the efficiency of the process are identified. These include: alloying, refining, modification, the use of various one-time coatings, the use of heat treatment of castings. The use of hard coatings applied by the method of physical vapor deposition in order to increase the efficiency of the entire casting process is proposed.
