Development of a technology is presented for preparing a workpiece of highly alloyed steel by plasma surfacing. Production possibilities for preparing a workpiece with layered synthesis during plasmatron operation with currents of forward and reverse polarity are studied. The possibility is demonstrated of growing a flange workpiece of highly alloyed steel 10Kh18N10T. A study of the workpiece microstructure shows that a multilayered surfaced workpiece has a very fine structure without defects. Good surfacing quality is confirmed by studying mechanical properties.
