초록
국산 Ni-Ti합금 교정용 선재(ORTHOLLOY)의 특성을 평가하기 위하여 성분, 인장특성, 굽힘특성, 열처리성, 내식성, 이온용출 등에 대해 조사하고 외국산 Ni-Ti합금 선재(SENTALLOY)의 특성과 비교 분석한 결과는 다음과 같았다. ORTHOLLOY는 초탄성 효과를 나타내는 범위내에서의 Ni과Ti 함량을 포함하고 있었다. 인장실험에서 ORTHOLLOY는 연신율
To estimate the characteristics of Korean Ni-Ti alloy orthodontic wire, this study investigated compositions, tensile properties, bending properties, heat treatment effects, and ion releasing degrees, and compared these characteristics to those of the imported Ni-Ti alloy wire. The results obtained are as follows ; 1. Ti and -Ni elements in ORTHOLLOY were in a range showing superelasticity, and there was a little difference in the Ni and Ti contents of ORTHOLLOY as compared with those of SENTALLOY. 2. The results of the tensile test concerning ORTHOLLOY exhibited a superelastic effect, indicating an area of a definite amount of stress in spite of the changes in the range from
