Modelling the Elements Reaction–Diffusion Behavior on Interface of Ti/Al2O3 Composite Prepared by Hot Pressing Sintering

Autor: Guopu Shi, Liu Zhang, Zhi Wang

Publikováno v: Metals, Vol 10, Iss 2, p 259 (2020)

Element reaction−diffusion of Ti/Al2O3 composite which was fabricated at various sintering temperatures, holding times, and a sintering pressure of 30 MPa has been discussed in the present research. Results show that the thickness of the reaction l

In situ reactive fabrication of ZrC–SiC coating on Cf/ZrC–SiC composite

Autor: Qinggang Li, Zhi Wang, Guopu Shi, Lifei Gong

Publikováno v: Journal of Asian Ceramic Societies, Vol 3, Iss 2, Pp 178-182 (2015)

ZrC–SiC coating on Cf/ZrC–SiC composite was fabricated via in situ reaction using zirconium powder, silicon powder, and phenolic resin as raw materials. The coated composites exhibited excellent oxidation performance. In particular, the coating c
