The initial data of properties of coverings from non-alloying ferrochromium put on samples from steel and titanium are received. Is established, that the electrospark coverings from purified ferrochromium have enough high heat resistance. For increase wear proofness perspective has appeared ferrochromium with a low level of clearing from impurity of introduction. The carried ou researches of phase structure of a superficial layer a have shown these феррохромом,, that its hardening is caused by formation carbides, oxisulphide and combined strengthened of phases.
