Abstract
An effective way to improve quality of metal layers of the 450Kh30M and 500Kh22B7 types by controlling the silicon content in hard-facing consumables is shown. The influence of silicon and aluminum content in hard-facing consumables on content of silicon, aluminum, chromium and carbon in the hard-faced layer as well as the amount of non-metallic inclusions of silicate type was studied to develop mathematical models and to derive corresponding dependencies. As a result some corrections to the composition of the hard-facing consumables were proposed to improve quality of metal layers of high-alloyed white cast irons of the investigated types.
