METAL SURFACE PROCESSING METHOD AND DEVICE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method capable of processing a surface of alloy by a simple process without discharging a substance which affects the environment. <P>SOLUTION: The metal surface processing method for processing a processing object portion on a surface of an Al-Si alloy 10 containing aluminum 11 which is processed when the fluence of pulse laser beam to be emitted is a processing threshold F<SB POS="POST">th</SB><SP POS="POST">Al</SP>or more and primary crystal silicon 12 which is processed when the fluence of the pulse laser beam to be emitted is a processing threshold F<SB POS="POST">th</SB><SP POS="POST">Eu</SP>or more which is different from the processing threshold F<SB POS="POST">th</SB><SP POS="POST">Al</SP>includes: steps of adjusting the fluence of the pulse laser beam to a value capable of exposing a desired substance on the surface of the Al-Si alloy 10 according to the processing threshold F<SB POS="POST">th</SB><SP POS="POST">Al</SP>and the processing threshold F<SB POS="POST">th</SB><SP POS="POST">Eu</SP>; and emitting the pulse laser beam with the adjusted fluence to the surface of the Al-Si alloy 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
