The method of arc surfacing of flat parts using fire-cracker plate electrode over alloying charge was offered. The main factors determining stability of surfacing process are the following: arc voltage U, arc current I, and electrode sectional area S. As a result of experiments the range of surfacing current (300-400 A) was determined providing stability of mode at the start and throughout the whole process of surfacing. It was established that hardness of deposited metal amounted to HRC 47-52, which is higher than that of metal such as steel G13. Metallographic investigations showed that the offered method provides a minimal penetration of base metal, that will allow obtaining the necessary chemical composition of deposited metal in single-layer surfacing. 4 Ref., 2 Tables, 3 Figures.
