Joining the reaction bonded silicon carbide(RB-SiC) by a new-type reaction-formed joint technology which developed from the traditional reaction-formed joint process. Testing the thickness
microstructure
mechanical and thermal properties of the welding line. The test results show that the welding line’s thickness is very thin
during 54-77μm
and its microstructure is similar to the RB-SiC ceramic
so its mechanical property is excellent
the average bending strength of 10 joints is 307MPa. And the welding line didn’t influence the surface figure before and after the temperature of the joining blank changed fast from -10℃ to 65℃ three times.
