Description
Известны Порошковые .проволоки, состо щие ИЗ .малоуглеродистой стальной оболочки и порошкообразного сердечника. Заполнение проволоки сердечником из различных раздробленных до состо ни порошка материалов, в основном ферросплавов, позвол ет получить твердый и износостойкий направленный металл . Известна порошкова .проволока, в состав шихты которой входит до 2% карбида бора.Powderwires are known, consisting of FROM a low carbon steel sheath and a powdered core. Filling the wire with a core of various crushed to powder materials, mainly ferroalloys, provides a hard and wear-resistant directional metal. Known powder wire, the composition of the charge which includes up to 2% boron carbide.
С целью повышени твердости и износостойкости «вплавленного металла -предлагаетс следующий состав щихты сердечника проволоки: карбида бора 25-55%, железиого порошка остальное.In order to increase the hardness and wear resistance of the “melted metal”, the following composition of the core wire is proposed: boron carbide 25-55%, iron powder the rest.
