“…This yields the elastic strain energy in the C-C/Cu-clad-Mo joints in the range 31-180 mJ, which is roughly of the same order as the U eC (~ 0.5-80 mJ) of a number of ceramic-metal joints [16][17][18].…”

“…Analytical and numerical models [16][17][18][19][20][21] have been developed to determine the residual stresses at joints between dissimilar materials. For example, Eager and coworkers [16][17][18] have developed numerical and analytical models of residual stress relief by metal interlayers taking into account the CTE mismatch and interlayer plasticity.…”

Carbon-carbon composites with either pitch+CVI matrix or resin-derived matrix were joined to copper-clad molybdenum using two active braze alloys, Cusil-ABA (1.75% Ti) and Ticusil (4.5% Ti). The brazed joints revealed good interfacial bonding, preferential precipitation of Ti at the composite/braze interface, and a tendency toward de-lamination in resin-derived C-C composite due to its low inter-laminar shear strength. Extensive braze penetration of the inter-fiber channels in the pitch+CVI C-C composites was observed. The relatively low brazing temperatures (<950°C) precluded melting of the clad layer and restricted the redistribution of alloying elements but led to metallurgically sound composite joints. The Knoop microhardness (HK) distribution across the joint interfaces revealed sharp gradients at the Cu-clad-Mo/braze interface and higher hardness in Ticusil (~85-250 HK) than in Cusil-ABA (~50-150 HK). These C-C/Cu-clad-Mo joints with relatively low thermal resistance may be promising for thermal management applications.

“…However, NDT techniques calibrated against metallographic examinations and mechanical tests can form a basis for reliable NDT test in manufacturing components for critical applications as in the aerospace and nuclear industry [Escourbiac et al, 2007;Ezato et al, 2002;Mergia et al, 2009;. The meatallographic type examinations of the joints as well as mechanical tests are well known and will not be referred here [Kim & Lee, 1998;Park J.-W et al, 2002;Jadoon et al, 2004;Takahashi et al, 2003;Galli et al, 2009;Lee et al, 1995;Serizawa et al, 2006;Serizawa et al, 2007;Serizawa et al, 2008;]. However, some advanced techniques not widely used and not well known need to be mentioned.…”

“…With the development of novel techniques for producing ceramics, more and more interest has been focused on their use in advanced engineering designs. 1 However, because of their brittle nature, poor formability and high manufacturing cost, it is highly desirable to fabricate metal-ceramic joints in the systems and the successful performance of such systems depends on the quality and reliability of the ceramic-to-metal joints. Therefore, searching for the proper joining processes for the fabrication of metal-ceramic joints for the various applications attracts many researchers' attentions in recent years.…”

A novel joining technique of ceramics to metals is presented, in which depositing Ti on ceramics with arc-added glow discharge is used as a prior metallizing technique and then brazing the ceramics to metals by abnormal glow discharge is carried out. The heating temperature of the base metals is easily controlled by varying the operating voltage and barometric pressure. The ions beam from the glow discharge anode is efficiently able to sputterclean the surfaces of the base materials, which thereby improves better Ti-deposited adhesion on the ceramics and the wetting and spreading properties of the filler metal. The thickness of the Ti-deposited layer is readily adjusted in terms of the actual requirement. The vacuum pressure during brazing can be up to 5 Pa. The cost and duration of the glow discharge plasma brazing are reduced as compared with the traditional vacuum brazing process. The joining technique developed holds potential for industrial applications leading to high product quality.
