摘要: Abstract Ductile cobalt-cladded Al 2 O 3 and TiC powder were prepared using a chemical deposition method. The mixture of Co-cladded (about 70 wt.% –Co + 30 TiC-Co) was hot-pressed into an –TiC–Co ceramic sample. Results presented in this paper demonstrated that ductile cobalt could clad the –TiC grains strengthened interfacial bonding grains. fracture toughness has been improved considerably, compared with TiC). surface sample exhibited some degrees plastic deformation, which behavior, although typical transgranular appeared within coarse
