| <P>PROBLEM TO BE SOLVED: To provide laser peening for forming a larger curve in thicker metal sections by generating strong stress fairly deep in a component. <P>SOLUTION: A light beam of 10-100 J/pulse is imaged to create an energy fluence of 60-200 J/cm<SP>2</SP>on an absorptive layer applied over a metal surface.

| (57)【要約】 金属被加工物の表面上にレーザによって誘起される圧縮応力を生じさせることによって金属部分に形状および輪郭を与えるための方法および装置が提供される。 このレーザ加工法は、金属表面に不必要な引張り応力を誘起することなしに厚い部品をも形状付けするために、深い圧縮応力を生じさせることができる。 レーザによって誘起される応力の精度の高さは、正確な予測およびその後に続く部品の正確な輪郭付けを可能とする。 金属表面上の吸収層に６０〜２００ジュール／平方センチメートルのエネルギ流束量を生じさせるために、１パルス当たり１０〜１００ジュールの光ビームが投影される。 水の充填層が吸収層上に流される。 レーザ光線の吸収はプラズマの形成を生じさせ、その結果として金属に深い残留圧縮応力を誘起する衝撃波を生じさせる。 金属は曲がることによってこの残留応力に反応する。 | ||||||

| PROBLEM TO BE SOLVED: To provide a method for highly durable identification marking on a component without practically changing the physical shape of the component. SOLUTION: Durable component-marking is realized by local modification on the surface of a material. The property in the specific surface regions (106, 110) of the component is changed without practically changing the physical shape of the component. By arranging these changes in a consistent pattern, the method for highly durable identification marking can be obtained. After that, by detecting and interpreting the consistent pattern, the original identification mark can be found. Different from labeling, ink marking, stamping, or etching, the many surface modification on the surface, or the modification in the vicinity of the surface is not necessarily seen by the human eyes. Therefore, this method contains (1) a method for surface modification, (2) a method for enhancing readout ability and accuracy in the readout of coded data, and (3) a method for deciding the position of the surface change. | ||||||
