Disclosed herein are embodiments of wear resistant alloys, such as ferrous alloys, that can have reduced carbide contents. In some embodiments, the alloys may have no carbides. In some, the alloy may have boride phases, such as phases having high Mo+W content and/or high Fe+Cr content. There can be reduced hardphases levels out of the specifically disclosed boride phases in some embodiments. In some embodiments, hypereutectic chromium borides can have limited incorporation into the disclosed alloys.

Reduced carbides ferrous alloys

Disclosed herein are embodiments of iron-based alloys. The alloys can be powders used as a feedstock for plasma or thermal spray processes. In some embodiments, the alloys can have low or no chromium, provided improvements from an environmental and worker health perspective. In some embodiments, the powder can have a generally large particle size.

Thermal spray iron-based alloys for coating engine cylinder bores

Disclosed herein are embodiments of a powder feedstock, such as for bulk welding, which can produce welds. The powder feedstock can include high levels of boron, and may be improved over previously used cored wires. Coatings can be formed from the powder feedstock which may have high hardness in certain embodiments, and low mass loss under ASTM standards.

Powder feedstock for wear resistant bulk welding configured to optimize manufacturability

Disclosed herein are embodiments of hardfacing/hardbanding materials, alloys, or powder compositions that can have low chromium content or be chromium free. In some embodiments, the alloys can contain transition metal borides and borocarbides with a particular metallic component weight percentage. The disclosed alloys can have high hardness and ASTM G65 performance, making them advantageous for hardfacing/hardbanding applications.

Chromium free and low-chromium wear resistant alloys

Embodiments of wear resistant ferrous alloys are disclosed herein. In some embodiments, ferrous alloys can have a matrix which includes near spherical and hypereutectic borides and/or borocarbides while at the same time avoiding the formation of rod-like borides and/or borocarbides. In some embodiments, the wear resistant ferrous alloys can be used as a coating, such as a hardfacing layer, to add protection to different components.
