(2) With the addition of flux cored wire in the increase of boron carbide B4C, Fe-Cr-Ti-B surfacing alloy hardness and wear resistance increases firstly and then the relative decline, when the addition of 5% B4C , its hardness and relative wear resistance to achieve the best value, but adding too much oxygen scavenger flux cored wire. such as aluminum and magnesium powder. not conducive to improving its hardness and wear resistance.
