摘要
本研究对GI-Ⅱ型镧系、铈系玻璃料渗透Vita In-Ceram氧化铝以后渗透陶瓷试件的三点弯曲强度进行了测试,并与GI-Ⅰ型及Vita In-Ceram玻璃料渗透同种氧化铝的情况进行了对比研究.结果表明:四种玻璃渗透的渗透陶瓷,三点弯曲强度均在366～409MPa.单因素方差分析四组的强度值差异不具有显著性;玻璃成分中以铈部分取代镧是成功的;在玻璃和氧化铝两个影响渗透陶瓷强度的因素中,氧化铝的影响更为关键.
In this study, flexural strength of vita In - ceram alumina specimens infiltrated with G1-Ⅱ La and G1-Ⅱ Ce glass were determined by means of three point bending test,and were compared with those of the specimens infiltratedwith G1-Ⅱ and vita In - ceram glass. The results showed:①The flexuralstrength of alumina specimens infiltrated with four glass determined by means of three- point bending test all attained a value of 366-409 MPa, One - way anova revealed an insignificant difference among four groups. ②Partially replacement of La with Ce in the glass proved to be successful. ③Of the two factors which determine the strength of infiltrated ceramic, alumina has greater influence on the flexural strength than glass does.
