HfB2-SiC-MoSi2 oxidation resistance coating fabricated through in-situ synthesis for SiC coated C/C composites

Fabrication of Ti3SiC‌‌2-SiC max phase composites via in-situ and ex-situ synthesis

Recently, a series of three-component compounds with the combination of Mn+1AXn known as Max phases have been considered as a new material. One of the most important features of Max phases, is the self-healing property of them. The main reason for considering Max Phases is a unique collection of unusual properties including their metallic, ceramic, physical, and mechanical properties. One of th...

Oxidation 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 ...

Protection against oxidation of C/SiC composites: oxidation behaviour of CVD TiB2 coated substrates

High Thermal Conductivity SiC/SiC Composites for Fusion Applications

SiC-SiC composites offer excellent potential for fusion energy as well as numerous commercial applications. High manufacturing cost and very low through-the-thickness (transverse) thermal conductivity (below 15 W/mK) hinders wider applications of SiC/SiC composites. To overcome these obstacles, a low-cost, Chemical Vapor Reaction (CVR) process was developed to fabricate crystalline, high purity...

OXIDATION OF C/SiC COMPOSITES AT REDUCED OXYGEN PARTIAL PRESSURES

T-300 carbon fibers and T-300 carbon fiber reinforced silicon carbide composites (C/SiC) were oxidized in flowing reduced oxygen partial pressure environments at a total pressure of one atmosphere (0.5 atm O2, 0.05 atm O2 and 0.005 atm O2, balance argon). Experiments were conducted at four temperatures (816°, 1149°, 1343°, and 1538°C). The oxidation kinetics were monitored using thermogravimetr...
