TL;DR: In the presence of carbon or silicon carbide, silica can be reacted to form a vapor of silicon monoxide and the rates of these reactions were explored at 1300° to 1550°C as mentioned in this paper.
Abstract: In the presence of carbon or silicon carbide, silica can be reacted to form a vapor of silicon monoxide. The rates of these reactions were explored at 1300° to 1550°C. For mixtures of carbon and silica, evidence supported a two-step reaction: silicon carbide formed prior to reaction between silicon carbide and silica.

TL;DR: In this article, radio frequency sputtering was used to deposit refractory carbide, silicide, and boride coatings on 440-C steel substrates and the films were deposited with and without a substrate bias.
Abstract: Radio frequency sputtering was used to deposit refractory carbide, silicide, and boride coatings on 440-C steel substrates. Both sputter etched and pre-oxidized substrates were used and the films were deposited with and without a substrate bias. The composition of the coatings was determined as a function of depth by X-ray photoelectron spectroscopy combined with argon ion etching. Friction and wear tests were conducted to evaluate coating adherence. In the interfacial region there was evidence that bias may produce a graded interface for some compounds. Biasing, while generally improving bulk film stoichiometry, can adversely affect adherence by removing interfacial oxide layers. Oxides of all film constituents except carbon and iron were present in all cases but the iron oxide coverage was only complete on the preoxidized substrates. The film and iron oxides were mixed in the MoSi2 and Mo2C films but layered in the Mo2B5 films. In the case of mixed oxides, preoxidation enhanced film adherence. In the layered case it did not.

TL;DR: In this paper, wear tests on high-speed steels of the same chemical composition but different carbide distributions induced by different manufacturing routes are considered, showing that the manufacturing route of the steel plays a major roll on its wear performance.
