FIELD: metallurgy.
SUBSTANCE: invention relates to metal forming and can be used for hardening by explosion in surface layer of metal. A device containing a detonating charge of an explosive in the form of an upper layer of a plastic explosive and a thinner lower layer of a mixture of solid loose material and an adhesive binder is installed on the hardened surface of the article.
EFFECT: enlarging technological capabilities of the device due to possibility of its fixation on the article surface and hardening of the metal of the article at significant depth in places with complex surface relief.
