Abstract

The review analyzes the current state of production of HNA (Heat-resistant nickel alloy) granules by the method of plasma melting and centrifugal spraying of a cast rotating blank (PREP method). The main theoretical and practical features of the production of HNA granules by this method are shown. Based on the analysis of a number of works in a similar direction, the corresponding calculations are made, allowing to form a list of requirements for the production of granules using the method of plasma melting and centrifugal spraying of a cast rotating blank.
