| 发明名称 | Laser hardened surface for wear and corrosion resistance | ||
| 摘要 | A method of laser hardening comprises irradiating a surface of a component with a laser beam to form a first band of irradiated material, irradiating the surface of the component with the laser beam to form a second band of irradiated material that overlaps the first band of irradiated material, where the first band and the second band have a pitch to width ratio of between about 0.5 and about 0.78. | ||

| 主权项 | 1. A method of laser hardening comprising: irradiating a surface of a component with a laser beam to form a first band of irradiated material, wherein irradiating the surface comprises heating the surface while remaining below the component's melting point; and irradiating the surface of the component with the laser beam to form a second band of irradiated material that overlaps the first band of irradiated material, wherein the second band is adjacent the first band; wherein the first band and the second band have a pitch to width ratio of between about 0.63 and about 0.78. | ||
