FIELD: powder metallurgy, in particular, compositions for plasma spraying, protection of parts against wear, reconditioning of worn surfaces. SUBSTANCE: a predetermined amount of aluminum oxide is added into wire tube burden. Improved wire tube has steel casing and wire tube burden containing, by weight: carbon 0.47-0.51; chromium 2-4; aluminum oxide 10-15; iron the balance. EFFECT: increased abrasive wear- resistance of products from tube wire. 1 tbl
