Abstract
The invention relates to a method of protecting a surface, comprising: providing a surface; and applying an initially--formed layer of a material on the surface, the material comprising at least 55% Fe by weight and fewer than 10 additional elements, the fewer than 10 additional elements comprising at least two of B, C and Si, the initially-formed layer comprising an initial hardness of at least about 9.2 GPa, having a tensile elongation of from about 0.5% to about 60%.
Claims (5)
1. A method of protecting a surface, comprising:
providing a surface; and applying an initially-formed layer of a material on the surface, the material comprising at least 55% Fe by weight and fewer than 10 additional elements, the fewer than additional elements comprising at least two of B, C and Si, the initially-formed layer comprising an initial hardness of at least about 9.2 GPa, having a tensile elongation of from about 0.5% to about 60%.
providing a surface; and applying an initially-formed layer of a material on the surface, the material comprising at least 55% Fe by weight and fewer than 10 additional elements, the fewer than additional elements comprising at least two of B, C and Si, the initially-formed layer comprising an initial hardness of at least about 9.2 GPa, having a tensile elongation of from about 0.5% to about 60%.
2. The method of claim 1, wherein the surface is a metallic surface.
3. The method of claim 1 or 2, wherein the initially-formed layer comprises an amorphous structure.
4. The method of any one of claims 1 to 3, further comprising:
converting the initially-formed layer into a hardened layer comprising an increased hardness, the increased hardness being greater than the initial hardness.
converting the initially-formed layer into a hardened layer comprising an increased hardness, the increased hardness being greater than the initial hardness.
5. The method of claim 4, wherein the hardened layer comprises a nanocomposite microstructure having a grain size of from about 75 nm to about 125 nm, and having second phase precipitates of about 20 nm at grain boundaries.
