چکیده انگلیسی
In the present work, amorphous CuTiZrNi foils with low melting point of 1133Â K were synthesized using a melt-spinning method in argon atmosphere. A ZrB2-SiC ultra high temperature ceramic was brazed at 1153-1253Â K for 900Â s. The wetting and spreading characteristics of amorphous alloy filler on the ceramic were studied with the sessile drop method. The reaction products between the ZrB2-SiC ceramic and the CuTiZrNi filler were systematic studied by X-ray diffraction and scanning electron microscopy. Also, the formation process of interfacial product of joint was discussed. A maximum room temperature three-point bending strength of 210Â MPa of the joint was obtained by reasonable processing. The high temperature strength of the joint was also studied, and the joint was found to exhibit a stable strength (240Â MPa) at a high temperature of 873Â K. The presence of refractory Ti5Si3 compound was believed to be contributed to the stable high temperature strength.
