Methods of Investigation of the Deposited Metal Properties and Their Application for the Development of Flux Cored Wires

Methods and samples have been developed and improved for comprehensive evaluation of the operational properties of materials for deposited elements and tools for pressure metal processing. In particular, the method of assessing the wear resistance of deposited metal at room (20°C) and elevated (600°C) temperatures, as well as the thermal resistance of deposited metal was improved. Designs of samples and optimal test modes, which simulate their real operating conditions, were chosen. The introduction of the boron microadditives in the amount of 0.01% leads to an increase in the operational properties of the deposited 25Kh5FMS and 35V9Kh3SF steels in 1.2–1.6 times. According to these results, the composition of the flux cored FCW-Dep-25Kh5FMS and FCW-Dep-35V9Kh3SF wires was improved due to the addition of FMI-2 ligature containing boron.
