本研究以惰性氣體鎢極電弧銲接，分別將鎳基合金Inconel 52M及Inconel 82 被覆於SUS 316L上，並觀察母材與被覆層之間的銲接形貌、機械性質、微觀組織、化學分析及抗蝕性，並探討Inconel 82 取代Inconel 52M作為SUS 316L被覆層的可行性。
實驗結果顯示，銲接材料成份影響銲後的各項性質，由於Inconel 82的樹枝狀組織較Inconel 52M細，造成硬度及拉伸強度上的提升；在抗蝕性方面，由於Inconel 52M與Inconel 82鉻及鎳的含量高，抗蝕性較SUS 316L佳，其中Inconel 52M的鉻含量又較Inconel 82高，因此被覆Inconel 52M的抗蝕效果比被覆Inconel 82的抗蝕效果來的好。

This study clads Inconel 52M and Inconel 82 on SUS316L by Gas Tungsten Arc Welding. After processing clads, we observe the region between base metal and filler metal for its macrostructure, mechanical properties, microstructure, chemical analysis, and corrosion resistance test for the possibility of Inconel 82 substitutes for Inconel 52M.
The results show that the chemical components of filler metal affect many propreties after welding. Because the dendrite microstructure in Inconel 82 is denser than in Inconel 52M, the tensile strength of Inconel 82 is better than Inconel 52M. In corrosion resistance, the higher the cladded layer, the higher the corrosion resistance. The Inconel 52M weldments have better corrosion resistance than Inconel 82 weldments, because Inconel 52 have higher Cr content than Inconel 82.
