Fabrication and inspection of C/Cf-ZrB2-ZrC-SiC and C/Cf-ZrB2-SiC composite parts resistant to ablation by pressureless sintering method
In this research, the aim is to achieve strong and ablation-resistant composite parts C / Cf-ZrB2-ZrC-SiC and C / Cf-ZrB2-SiC by non-pressure sintering method. C / Cf-ZrB2-SiC samples were prepared using synthesized ZrB2 and SiC powders between layers of resin-impregnated carbon fabric. After pressing with pressure 5 times at 1600 وC and heat treatment for 2 hours in a controlled atmosphere fur...
متن کاملOxidation of ZrB2-SiC Composites at 1600 °C: Effect of Carbides, Borides, Silicides, and Chopped Carbon Fiber
The aim of this work is to optimize the oxidation resistance of ZrB2-SiC-based composites with different additives. Effect of nine factors including SiC, Cf, MoSi2, HfB2 and ZrC contents, milling time of Cf (M.t) and SPS parameters such as temperature, time and pressure on oxidation resistance in four levels was investigated. Taguchi design was applied to explore effective parameters for ...
متن کاملOn the Properties of WC/SiC Multilayers
A study of the materials properties of WC/SiC multilayer coatings is presented. We investigated the dependence of interface and surface roughness, intrinsic stress, microstructure, chemical composition, and stoichiometry as a function of multilayer period and in some cases compared these to W/SiC multilayer systems. The WC/SiC material pair forms multilayers with extremely smooth and sharp inte...
متن کاملCo-Dispersion Behavior of ZrB2–SiC–B4C–C Powders with Polyethyleneimine
The aqueous dispersion behavior of ZrB₂, SiC powders with B₄C and C as sintering aids was investigated. Well co-dispersed suspension can be obtained in acidic solutions in presence of polyethyleneimine (PEI). The adsorption of PEI on the powder surface was measured by thermal gravimetric (TG) analysis. Rheological measurements displayed the effect of dispersant on the flow behavior of as-prepar...
