摘要註:	本論文以低溫滲碳製程(LTCSS)對316及316L不銹鋼板表面進行滲碳處理。實驗選用市售SUS316及SUS316L不銹鋼板，並施予0hr、12hr、24hr及36hr之低溫滲碳處理，實驗後，經顯微組織、成份、硬度測試以及XRD結構等分析方法探討316及316L不銹鋼於低溫滲碳處理製程後之滲碳效果。由微觀組織分析結果發現，在滲碳時間相同時，316不銹鋼具有較厚的滲碳層，此結果意謂316較易形成滲碳層，滲碳層之成長速度亦較快。另外，從成分分析結果發現，316不銹鋼板經低溫滲碳處理後，所能提升的碳含量較高，全滲碳深度成長較快且較厚。從硬度檢測結果得知，相較於316L不銹鋼，316不銹鋼形成滲碳硬化層所需的時間較短，且硬化的效果較佳。此現象於0 hr試片之差異最大，但隨滲碳時間增加，硬化層厚度的成長速度之差異有變小的趨勢。而以顯微組織、成分分析以及硬度測試檢測結果發現，不論是316不銹鋼還是316L不銹鋼的成分分析之全滲碳層厚度與金相所觀察到的滲碳層及硬度測試所測得的硬化層厚度雖無完全吻合，但變化趨勢相近。從結構分析結果發現，316不銹鋼經低溫滲碳後效果較佳，推測為合金內部之碳原子有利於後來之碳原子擴散。 Low-temperature carburization treatment was developed to increase the surface hardness of austenitic stainless steels. The objective of this study is to clarify the low temperature carburizing on 316 and 316L stainless steel. The characteristic of carburization layer was analyzed by microstructure, carbon concentration, hardness testing and X-ray diffraction after low-temperature carburization for 0, 12, 24, and 36 hrs at 500 ℃.From microstructure analysis results, a thicker carburization was formed in the 316 stainless steel. Compared with 316L stainless steel, the 316 stainless steel has higher growth rate of carburization layer during the carburizing time from 12 to 36hrs. And the 316 stainless steel is easy to form the carburizing layer in the matrix.From carbon concentration analysis, the carbon concentration and thickness of carburization zone were increased obviously after low-temperature carburization treatment in the 316 stainless steel. In hardness test, the hardening layer was formed in a shorter time in the 316 stainless steel. The hardening effect of higher carbon content steel is better than that of 316L stainless steel. The difference of hardening layer became smaller, when the carburization time was increased. Actually, the depth of full-carburization zone had been changed in the same tendency from the results of microstructure analysis, carbon concentration analysis and hardness testing analysis as the carburization time increased.From XRD microstructure analysis, the effect of low-temperature carburization in the 316 stainless steel is better than 316L stainless steel. This was thought because the lattice constant was expanded and resulted in the carbon atom diffusing more easily.
