Abstract

本发明公开了一种牙科合金。本发明属于合金材料制备领域。一种牙科合金,其特征在于:按照质量比,所述牙科合金由60~70%Co,掺杂15~20%Cr,10~20%Mo,0~1%Ni,0~1%Ti,0~1%Al,和0~1%Re组成。本发明是由非高贵金属和贵金属合金制造的,生物相容性好。

Description

一种牙科合金
技术领域:
本发明属于合金材料制备领域,尤其涉及牙科合金制备领域。
 
背景技术:
合金是2种或2种以上金属的混合物,牙科合金通常包含至少4种金属,甚至6种以上。大多数合金是以金为主要元素,也有钯、银、镍、钴和钛,次要元素种类更多,元素周期表中25种以上的元素都可用于牙科合金。牙科铸造合金直接置于口腔内,要求具有良好的生物相容性。但是合金在体液的作用下会发生腐蚀,导致毒性的组织反应。现有的牙科铸造合金中,单相结构的高贵金属和贵金属合金生物相容性最好。但是,高贵金属和贵金属合金价格昂贵。因此,希望有非高贵金属和贵金属合金制造的,生物相容性好的牙科材料。
 
本发明的目的是设计一种非高贵金属和贵金属合金制造的,生物相容性好的牙科材料。
 
本发明的技术方案是:一种牙科合金,其特征在于:按照质量比,所述牙科合金由60~70%Co,掺杂15~20%Cr,10~20%Mo, 0~1%Ni, 0~1%Ti,0~1%Al,和0~1%Re组成。
 
本发明的有益效果是:
非高贵金属和贵金属合金制造的,细胞毒性小,生物相容性好的牙科材料。
 
本发明具体实施方式:
实施例1:按照质量比,所述牙科合金由60%Co,掺杂20%Cr,16%Mo, 1%Ni, 1%Ti, 1%Al,和1%Re组成。
实施例2:按照质量比,所述牙科合金由70%Co,掺杂15%Cr,18%Mo, 1%Al,和1%Re组成。

Claims (2)

1.一种牙科合金,其特征在于:按照质量比,所述牙科合金由60~70%Co,掺杂15~20%Cr,10~20%Mo, 0~1%Ni, 0~1%Ti,0~1%Al,和0~1%Re组成。
2.根据权利要求1所述的一种牙科合金,其特征在于:按照质量比,所述牙科合金由60Co,掺杂20%Cr,20%Mo, 1%Ni, 1%Ti,1%Al和1%Re组成。
