Abstract
The structure and properties of surface layers of billets from steel 12Kh18N9T formed by vacuum electron beam surfacing of powder mixtures are studied. The main alloying component is molybdenum in an amount of 40 wt.%. The structural and phase studies are made using optical and electron microscopes and an x-ray diffractometer. The microhardness and the wear resistance of the deposited layers are determined. The structure of the hardened surface layer is shown to contain phases Mo0.08Fe0.92, Mo0.9Fe0.1, Mo0.1Fe0.9, α-Fe and γ-Fe. The alloying with molybdenum raises the wear resistance of the steel by a factor of 1.8 and the heat resistance by a factor of 6.7.
