Claims
- 1. A laser padding material comprising copper (Cu) as a main component and, as other contained elements, 1-5 weight % of nickel (Ni), 0.2-5 weight % of silicon (Si) and at least one deoxidizing element selected from the group consisting of: less than 1 weight % of boron (B), less than 2 weight % of phosphorus (P) and less than 3 weight % of manganese (Mn).
- 2. A laser padding material as set forth in claim 1, wherein said contained elements are provided respectively in the form of powder of a substance consisting of one or more of the elements.
- 3. A laser padding material as set forth in claim 1, wherein said contained elements are provided in the form of copper alloy powder.
- 4. A laser padding material as set forth in claim 1, further comprising ceramic powder.
- 5. A laser padding material as set forth in claim 4, wherein said ceramic powder is alumina ceramic powder.
- 6. A laser padding material as set forth in claim 1, wherein said nickel and silicon are provided to be 2 to 1 in molar ratio.
- 7. A laser padding material comprising copper (Cu) as a main component and, as other contained elements, 1-5 weight % of nickel (Ni), 0.2-5 weight % of silicon (Si) and at least one deoxidizing element selected from the group consisting of: less than 1 weight % of aluminum (Al) and less than 1 weight % of calcium (Ca).
- 8. A laser padding material as set forth in claim 7, wherein said contained elements are provided respectively in the form of powder of a substance consisting of one or more of the elements.
- 9. A laser padding material as set forth in claim 7, wherein said contained elements are provided in the form of copper alloy powder.
- 10. A laser padding material as set forth in claim 7, further comprising ceramic powder.
- 11. A laser padding material as set forth in claim 10, wherein said ceramic powder is alumina ceramic powder.
- 12. A laser padding material as set forth in claim 7, wherein said nickel and silicon are provided to be 2 to 1 in molar ratio.
- 13. A laser padding material comprising copper (Cu) as a main component and, as other contained elements, 1-5 weight % of nickel (Ni), 0.2-5 weight % of silicon (Si) and at least one deoxidizing element selected from the group consisting of: less than 1 weight % of boron (B), less than 2 weight % of phosphorus (P), less than 3 weight % of manganese (Mn), 8-15 weight % of tin (Sn), 8-15 weight % of lead (Pb), and less than 2 weight % of titanium (Ti).
- 14. A laser padding material comprising the steps of:
- supplying, onto a metal base material, material powder which includes copper as a main component and, as other contained elements, 1-5 weight % of nickel (Ni), 0.2-5 weight % of silicon (Si), and at least one deoxidizing element selected from the group consisting of: less than 1 weight % of boron (B), less than 2 weight % of phosphorus (P), and less than 3 weight % of manganese (Mn); and
- irradiating a laser beam on said material powder in an inert gas atmosphere,
- and wherein the material powder is melted on said metal base material to form a laser padded layer thereon.
- 15. A laser padding method as set forth in claim 14, wherein said supplying step is carried out by supplying said contained elements in the form of powder of a substance consisting of one or more of the elements.
- 16. A laser padding method as set forth in claim 14, wherein said supplying step is carried out by supplying copper alloy powder including said contained elements.
