Abstract
Laboratory data indicate the positive effects of introducing fluorocarbon and nickel in 25Kh5FMS steel powder wire for the surfacing of rollers. In particular, the replacement of amorphous carbon by a material containing fluorocarbon lowers the content of nonmetallic inclusions in the applied layer, while introducing nickel in the powder wire reduces the austenite grain size and ensures the formation of small carbide particles. That increases the thermal stability of the applied layer. Increase in the carbon equivalent of the 25Kh5FMS powder wire boosts the hardness of the applied metal layer.
