POWDER MADE OF IRON-BASE METALLIC GLASS |
摘要 |
The present invention is to provide powder made of iron-based metallic glass, the corrosion resistance of which is improved over the conventional powder made of iron-based metallic glass. The basic composition includes a group of iron-based metallic elements that predominantly has Fe, a group of metalloid elements that consists of Si, B, P, and C, and a little amount of a group of elements for improving the degree of supercooling that consists of either or both of Nb and Mo. The powder made of the iron-based metallic glass is obtained by adding to the basic composition an element for improving the corrosion resistance. The obtained powder made of the iron-based metallic glass has an excellent corrosion resistance, an excellent magnetic property, and an excellent insulating property. |

1. Powder made of iron-based metallic glass, wherein the iron-based metallic glass consists of a group of iron-based metallic elements, a group of metalloid elements, and a group of elements for improving the degree of supercooling (M: either or both of Nb and Mo), wherein a nominal composition of the iron-based metallic glass is expressed by (Fe1-s-tCosNit)100 -x-y{(SiaBb)m(PcCd)n}xMy wherein ratios of the compositions of the group of iron-based metallic elements are 19≦x≦30, 0<y≦8.0, 0≦s≦0.35, 0≦t≦0.35, and s+t≦0.35, wherein ratios of the compositions of the group of metalloid elements are (0.5:1)≦(m:n)≦(8.1); (2.5:7.5)≦(a:b)≦(5.5:4.5); and (5.5:4.5)≦(c:d)≦(9.5:0.5), and wherein either or both of Cr and Zr are added to the iron-based metallic glass as an element for improving the corrosion resistance, the content of the element for improving the corrosion resistance being 0.30-5.5 wt % in relation to the total contents of all the elements. |
