COMPOSITION OF POWDER MATERIAL FOR RESTORATION OF CONSTRUCTION MACHINERY AND ROAD MACHINES DETAILS Russian patent published in 2008 - IPC C23C4/04 B23K9/04 

FIELD: metallurgy.

SUBSTANCE: invention concerns composition of powder material for plasma fusing of coatings and can be used in mechanical engineering for restoration of details' worn surface of construction machinery and road machines. Composition includes mixture of powder based on iron and powder based on nickel. At that powder based on iron contains, wt %: carbon 3.3-3.5, silicon 2.0-2.5, manganese 10-12, boron 2.5-3.0, titanium 3,0-4,0, iron -the rest. Powder based on nickel contains, wt %: carbon 0.9-1.5, chrome 16-18, silicon 4.5-5.0, boron 4.0-4.7, nickel - the rest. Content of powder based on iron and powder based on nickel in mixture is respectively 70-75% and 30-25%.

EFFECT: excluding of gaseous protective medium usage at plating at keeping of high endurance.
