FIELD: machine building.
SUBSTANCE: invention relates to a wear part of the mechanisms for moving the soil/rock, soil capture and/or loading of rock, such as excavators and loaders bucket teeth. The wear element includes a cast steel and at least one insert. Mentioned above insert is made of a three-dimensional cellular ceramic foam, and has an open-cell pore structure. Open-cell pore ceramic foam of the insert, as well as in the micropores in the walls of ceramic foam impregnated with molten steel, which has a composition, comprising wt %: Carbon from 0.15 to 0.35, silicon 1.0 to 2 manganese 0.5 to 1.5 chromium 0.5 to 2.5 nickel 0 to 2 and from 0 molybdenum, 15 to 0.35.
EFFECT: invention improves the wear resistance of the wear elements, increases their service life.
