POWDER WIRE FOR BUILDING UP Russian patent published in 2013 - IPC B23K35/368 

FIELD: process engineering.

SUBSTANCE: invention relates to arc surfacing of tools and part operated at high specific pressures and increased temperatures. Powder wire consists of low-carbon steep shell and powder fusion mix at the following ratio of components in wt %: chromium - 20.0-23.0, nickel - 6.0-8.0, ferromolybdenum - 8.0-9.0, ferrotitanium -0.2-0.6, nitrided chromium - 2.0-3.0, ultrafine powder of titanium carbonitride - 0.2-0.6, sodium fluorosilicate - 0.8-1.0, iron -1.3-9.3, shell low-carbon steel making the rest. Said ultrafine powder of titanium carbonitride features particle size of 0.01-0.1 mcm.

EFFECT: higher heat resistance of built-up metal, reduced resource intensity of building up.
