SURFACE TREATMENT METHOD FOR METAL MATERIAL AND FORCE SENSOR |
| 摘要 |
A surface treatment method for roughening a surface of a metal material by a laser beam includes: forming a roughened surface adhesion portion on the surface of the metal material by irradiating the laser beam on the surface of the metal material to form a plurality of roughened regions within the roughened surface adhesion portion, each of the roughened regions being formed in a circular shape having an outer ring adjacent to each other. The roughened regions are arranged to satisfy the following Equation (1):;0.5a<d<1.5a (1);where “a” is a diameter of the outer ring of each of the roughened regions, and “d” is a center pitch between adjacent roughened regions. |

1. A surface treatment method for roughening a surface of a metal material by a laser beam, the method comprising:
forming a roughened surface adhesion portion on the surface of the metal material by irradiating the laser beam on the surface of the metal material to form a plurality of roughened regions within the roughened surface adhesion portion, each of the roughened regions being formed in a circular shape having an outer ring adjacent to each other, wherein the roughened regions are arranged to satisfy the following Equation (1):
0.5a<d<1.5a (1) where “a” is a diameter of the outer ring of each of the roughened regions, and “d” is a center pitch between adjacent roughened regions. |
