| Summary: | 碩士 === 國防大學理工學院 === 兵器系統工程碩士班 === 100 === In this thesis, several commonly used industrial heat treatments such as annealing treatment or beta annealing were employed following electron beam welded (EBW) process of Ti-6Al-4V weldment. The correlation of the compositon of the produced oxide layer due to related annealing treatment and the corrosion resitance is investigated.
It appears that the corrosion resistnace of both fusion zone and base metal zone is significantly influenced by the thickenss of oxide scale. Thicker oxide scale mainly dominated by higher temperature presents better corrosion resistacne along with the fact that the thickness of the oxide scale in fusion zone is being larger than that of the base metal zone in all heat treated conditions.
