Abstract
A hard-faced composite article includes an iron-based substrate having a composition with less than 0.6% by weight of carbon, and a wear-resistance element joined to the iron-based substrate. The wear-resistance element has a metallic matrix and boron-containing regions dispersed through the metallic matrix.
Claims21
A hard-faced composite article comprising:
- an iron-based substrate having a composition with less than 0.6% by weight of carbon;
- and
- a wear-resistance element joined to the iron-based substrate, the wear-resistance element having a metallic matrix and boron-containing regions dispersed through the metallic matrix.
A hard-faced composite article comprising:
- a metallic substrate defining a first hardness;
- and
- a wear-resistance element joined to the metallic substrate, the wear-resistance element having a second, greater hardness and a composition that has alloy elements including boron, carbon, chromium and nickel, a combined amount by weight of boron and carbon being 0.6-6.5 and a combined amount by weight of nickel and chromium being 5-80.
A method of processing a hard-facing, the method comprising:
- forming a wear-resistance element having a metallic matrix and boron-containing regions dispersed through the metallic matrix.
