摘要

本研究藉由自行設計之雷射熱處理系統，探討不同功率之毫秒級脈衝雷射對於鎳基超合金Haynes 282進行在大氣環境下進行熱處理後，其顯微結構以及表面形貌變化之關係。結果顯示，因雷射系統高能量密度且加熱區域集中之特點，試片整體溫度隨功率增加而升高，並且在雷射直射區域表面相較於非直接照射區域發生顯著析出或氧化現象，此現象隨雷射功率提高而更加劇烈。試片在雷射光承受面生成多種金屬氧化物以及碳化物，可能導致能量吸收效率之提高。

This study investigates the relationship between different power levels of millisecond-pulsed laser and surface morphology changes of nickel-based superalloy Haynes 282 after heat treatment in atmospheric environment. By utilizing laser heat treatment system the results indicate that due to the high energy density and concentrated heating area characteristics of the laser system, the overall temperature of the specimens increases by increasing working power. Significant precipitation or oxidation phenomena occur on the surface of the specimens in the direct laser irradiation zone compared to the non-irradiated area. This phenomenon becomes more severe with higher laser power. The laser can cause the formation of different metal oxides and carbides on the surface of the specimens, which may enhance the laser's energy absorption efficiency.
