Description
本发明涉及陶瓷材料领域,具体地说就是提供了一种以TiC、TiN、Ti(C、N)、SiC为基体含高温合金相的陶瓷材料,其兼具有高硬度与良好的韧性,适合于制作刀具。
用陶瓷做刀具材料,如文献Yasutomi Yoshiyuki,Kita Hidenori,NakamuraKosuko,Jpn.Kokai,Tokkyo Koho Jp 0105976[8905976],1989和T.Zambtakis,J.L.Gulle,B.Willer,M.Daire,J Mater.Sci.,22(1987)1135-1140中提供的Si3N4、Al2O3等虽然具有较好的耐磨性,但是脆性问题不能解决,因而只适合于切削冷硬铸铁和淬火钢,而对大多数高韧性的钢种则不能切削。为提高这类陶瓷材料的韧性,曾有过利用ZrO2的马氏体相变消除裂纹尖端的应力集中来改善Al2O3韧性的报导K.Tsukuma,K.Ueda,K.Matsushita,and M.Shimada,JAm.Ceram.Soc.68(2)(1985)c-56和A.H.Heuer,J.Am.Ceram.Soc.70(10)(1987)689,断裂韧性值可达K1C=10 MPam1/2,高于普通陶瓷K1C=3~8 MPam1/2硬度值Hv=14 GPa,遗憾的是这种马氏体相变是不可逆的,300℃以上增韧效果全部失去,不能重复使用,即经历不了热疲劳环境。
本发明的目的在于提供一种陶瓷材料,使其既具有高的硬度又具有较强的韧性,且增韧效果稳定。
本发明以TiC,TiN,Ti(N,C)、SiC粉之一种或几种作为基体,以Ni,Ti,Al,Cr,Co粉之一种或几种作为烧结荆,并引入TiAl,NiTi,NiAl之一或几种作为高温合金相成份,其具体的配方如下(重量百分比)
烧结剂 高温合金相成份 基体
0.1~65 0.1~5 余量
其中烧结剂中各种元素成份有如下限定(按陶瓷材料总重量计)Ni 5~30,Ti 0.5~5,Al 0.1~2,Cr 5~30,Co 0.1~2。各种高温合金相成份限制如下(按陶瓷材料总重量计)TiAl0.1~5,NiTi0.1~1,NiAl0.1~5。本发明中Ni、Ti、Al、Cr、Co所起的作用主要是作为烧结剂,使得陶瓷材料更加致密,同时,它们又可部分地固溶到TiAl,NiTi,NiAl中去,或者相互间形成高温合金相,这种高温合金相具有马氏体相变,并且是可逆的,如Ti3Al-NiAl相等,从而达到陶瓷增韧的效果,同时能在热环境中反复使用而不丧失韧性。本陶瓷可用热压或烧结的方法成型,温度在1300℃~1600℃之间。本发明所提供的这种复合陶瓷断裂韧性可达20 MPm1/2以上,适合于切削高韧性的合金如不锈钢,化纤工业中的纤维,化工工业的塑料,也可作为其它耐磨件应用于机械、化工、电子等工业中,下面详述实施例。
实施例1
TiC粉6.4g、Ti粉0.2g、6061Al粉0.1、Cr粉3g,TiNi粉0.2g、NiAl粉0.1g,机械混合后在N2气中1300℃,1小时处理,干压成型,1550℃烧结,硬度为Hv=16Gpa,韧性K1C=20 MPam1/2。
实施例2
Ti(N,C)粉5.5g、Ti粉0.1g,Al粉0.05g、Ni粉2g、Cr粉2g、Co粉0.05g、NiAl粉0.1g、TiNi粉0.2g混合,干压成型,1300℃20 MPa压力下热压烧结。K1C=20MPam1/2,Hv=16 GPa。
