Abstract
The effectiveness of TiN ion-plating was examined with TiN ion-plated Co-Cr wires(.016“, .016”x.022“) on three different types of bracket(TiN ion-plated metal bracket ceramic bracket and plastic bracket). Maximum static frictional forces and characteristic curves obtained from the frictional characteristic graph, were compared and surface roughness of wires and bracket slots before and after friction experiment was observed by SEM. The obtained results were as follows
TiN ion-plating된 Co-Cr 선재(.016", .016"x.022")와 ion-plating되지 않은 선재(.016", .016"x.022")를 이용하고, 3 가지 종류의 브라켓(TiN ion-plating된 금속 브라켓, 세라믹 브라켓 및 플라스틱 브라켓)을 대상으로 마찰실험을 행하고, 거기에서 얻어진 마찰 특성곡선과 곡선으로부터 구한 최대 정지마찰력, 그리고 선재와 브라켓의 표면양상을 주사전자현미경으로 관찰하여 TiN ion-plating의 효과를 검토한 결과 다음과 같은 결론을 얻었다.
