High temperature oxidation of sintered TiC in an H2O-containing atmosphere

Influence of Microstructure on the Wear Behavior of SiC‐Reinforced Titanium‐Matrix Composites Lubricated by Water and by Ethanol

“…The elemental analysis using EDS indicated that the substances mainly consisted of titanium oxide (Table V). Titanium oxide appears to have been formed by the oxidation of Ti, TiC, and Ti 5 Si 3 C x 26–29 …”

Oxidation of titanium carbide–graphite hetero-modulus ceramics with low carbon content

“…Interaction between carbide phase and oxygen only seems to be simple at a glance. Though the first oxidation kinetics studies of carbides, including titanium carbide, date back to the 1950-1970s, 12-17 even the prolific production of recent publications, mostly due to the works by Shimada et al [18][19][20][21][22][23][24][25]30 and Gozzi et al, [26][27][28][29][30][31][32][33][34] has not completely clarified some features of the oxidation kinetics for these compounds, as the data available in literature are not only differed, but sometimes, it is in contradiction with each other. Various models (linear, parabolic, logarithmic, etc.)…”

Oxidation of HIPed TiC Ceramics in Dry O2, Wet O2, and H2O Atmospheres

“…T itanium carbide (TiC) is a high‐temperature structural material with a very high melting point (>3000°C), high hardness, and high electrical conductivity, but is oxidized at relatively low temperatures. The oxidation of TiC in O 2 or air has been performed by many researchers including the authors (S. S.) 1–7 . Recently, TiC‐based composite materials such as TiC–SiC have been produced with the aim of improving mechanical and oxidation‐resistance properties 8–13 …”

“…From the practical viewpoint, considerable attention needs to be paid to the use of solid TiC ceramics rather than the powder. In this respect, the oxidation of TiC ceramics fabricated by hot‐isostatic pressing was performed in H 2 O‐containing atmospheres to study the oxidation kinetics with microstructural observation of TiO 2 scales, 7 but the accelerating mechanism of oxidation by H 2 O vapor was not discussed. The present study describes the oxidation of dense TiC ceramics in O 2 , O 2 /H 2 O, and H 2 O atmospheres at 900°–1200°C in terms of the oxidation kinetics, gas evolution, and microstructure of oxide scale, and discusses the accelerating mechanism of oxidation of TiC ceramics in the presence of H 2 O vapor.…”

“…The oxidation of TiC in O 2 or air has been performed by many researchers including the authors (S. S.). [1][2][3][4][5][6][7] Recently, TiC-based composite materials such as TiC-SiC have been produced with the aim of improving mechanical and oxidation-resistance properties. [8][9][10][11][12][13] It is well known that the oxidation of Si-based materials such as SiC, Si 3 N 4 , or SiAlON is accelerated by H 2 O vapor through the dissolution of H 2 O in SiO 2 scale.…”
