Some opinions were put forward. For new composites emerging, it is necessary to develop new joining methods, particularly in the field of high temperature technique for joining ceramics to superalloys.展开更多

When a suitable composite interlayer material was adopted in the diffusion bonding of HPSN to K 500, the bending strength of the joints would be up to 216 MPa and 218 MPa at room temperature and 800℃ respectively.展开更多
