Brazing of ZrB2-SiC ceramic with amorphous CuTiNiZr filler
چکیده انگلیسی
In the present work, amorphous CuTiZrNi foils with low melting point of 1133 K were synthesized using a melt-spinning method in argon atmosphere. A ZrB2-SiC ultra high temperature ceramic was brazed at 1153-1253 K for 900 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 210 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 (240 MPa) at a high temperature of 873 K. The presence of refractory Ti5Si3 compound was believed to be contributed to the stable high temperature strength.
