Abstract
Official abstract text for this publication.
A method for producing a laminated member includes a step of spraying a mixture in a non-molten state including a plurality of precipitation hardening copper alloy particles and a plurality of hard particles that have non-spherical shapes having a median aspect ratio of equal to or more than 1.2 and are harder than the copper alloy particles onto a base substrate to form a coating layer on the base substrate.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a laminated member, the method comprising: a step of spraying a mixture in a non-molten state including precipitation hardening copper alloy particles and hard particles that have non-spherical shapes having a median aspect ratio of equal to or more than 1.2 and are harder than the copper alloy particles onto a base substrate to form a coating layer on the base substrate. 2. The method for producing the laminated member according to claim 1 , wherein an average particle size (d50) of the copper alloy particles and an average particle size (d50) of the hard particles are both equal to or less than 50 μm. 3. The method for producing the laminated member according to claim 1 , wherein an average particle size (d50) of the hard particles is within the range of 14 μm to 50 μm. 4. The method for producing the laminated member according to claim 1 , wherein the hard particles comprise at least one type of alloy particles selected from the group consisting of cobalt-based alloy particles, chromium-based alloy particles, nickel-based alloy particles and molybdenum-based alloy particles. 5. The method for producing the laminated member according to claim 1 , wherein a compressive strength of the copper alloy particles is within the range of 50 N/mm 2 to 110 N/mm 2 . 6. The method for producing the laminated member according to claim 2 , wherein an average particle size (d50) of the hard particles is within the range of 14 μm to 50 μm. 7. The method for producing the laminated member according to claim 2 , wherein the hard particles comprise at least one type of alloy particles selected from the group consisting of cobalt-based alloy particles, chromium-based alloy particles, nickel-based alloy particles and molybdenum-based alloy particles. 8. The method for producing the laminated member according to claim 3 , wherein the hard particles comprise at least one type of alloy particles selected from the group consisting of cobalt-based alloy particles, chromium-based alloy particles, nickel-based alloy particles and molybdenum-based alloy particles. 9. The method for producing the laminated member according to claim 6 , wherein the hard particles comprise at least one type of alloy particles selected from the group consisting of cobalt-based alloy particles, chromium-based alloy particles, nickel-based alloy particles and molybdenum-based alloy particles. 10. The method for producing the laminated member according to claim 2 , wherein a compressive strength of the copper alloy particles is within the range of 50 N/mm 2 to 110 N/mm 2 . 11. The method for producing the laminated member according to claim 3 , wherein a compressive strength of the copper alloy particles is within the range of 50 N/mm 2 to 110 N/mm 2 . 12. The method for producing the laminated member according to claim 4 , wherein a compressive strength of the copper alloy particles is within the range of 50 N/mm 2 to 110 N/mm 2 . 13. The method for producing the laminated member according to claim 6 , wherein a compressive strength of the copper alloy particles is within the range of 50 N/mm 2 to 110 N/mm 2 . 14. The method for producing the laminated member according to claim 7 , wherein a compressive strength of the copper alloy particles is within the range of 50 N/mm 2 to 110 N/mm 2 . 15. The method for producing the laminated member according to claim 8 , wherein a compressive strength of the copper alloy particles is within the range of 50 N/mm 2 to 110 N/mm 2 . 16. The method for producing the laminated member according to claim 9 , wherein a compressive strength of the copper alloy particles is within the range of 50 N/mm 2 to 110 N/mm 2 .
