Изобретение относитс .к химикотермической .обработке металлов и сплавов из расплавов. солей и может быть использовано в MaiUHHOcTpOHTeJib- ной, приборостроительной, металлургической и других отрасл х промышленности дл  повышени  износостойкости изделий .The invention relates to chemical-heat treatment of metals and alloys from melts. salts and can be used in MaiUHHOcTpOHTeJib, instrument-making, metallurgical and other industries to increase the durability of products.

Известен состав ванны дл  диффузионного борировани , содержащий кар- бид кальци  (10-40 вес.%) и буру (6090 вес.%) 1.The composition of the diffusion boron bath containing calcium carbide (10-40 wt.%) And borax (6090 wt.%) 1 is known.

Однако состав характеризуетс  низкой насыщающей способностью и трудо- 15 емкостью дроблени  и просеивани  карбида кальци .However, the composition is characterized by low saturability and labor capacity of crushing and sieving calcium carbide.

Известен также состав дл  жидкостного борировани , предусматривающий использование буры (45-85 вес.%), 20 борного ангидрида (5-15 вес.%) и магниевокальциевой лигатуры (10-40 вес.%)A composition for liquid boronation is also known, which involves the use of borax (45-85 wt.%), 20 boric anhydride (5-15 wt.%) And magnesium-calcium ligature (10-40 wt.%)
