TL;DR: In this article, the important principles that determine the establishment, growth and long-term maintenance of protective Cr2O3, Al 2O3 and SiO2 scales on hightemperature iron-, nickel-and cobalt-base alloys are reviewed and discussed.

TL;DR: In this paper, the authors examined the oxidation behavior of an Fe-27%Cr-4%Al alloy and similar alloys containing 0.023% and 0.82% Y in 1 atm oxygen at 1200°C and found that the oxide formed on the yttrium-free alloy develops a highly convoluted configuration, resulting from lateral growth of the oxide.

TL;DR: In this paper, a review of the models developed to account for the generation of oxide during sliding and the effects of such oxides on the rates of wear was presented, focusing on high-speed unidirectional sliding and low-speed reciprocating sliding.

TL;DR: In this paper, the authors reviewed the main findings of extensive research programs into the development of wear-protective layers, including a model that accounts closely for the observed effects of temperature on wear rates during like-on-like sliding, and showed that at low temperatures, the layers generally consist of loosely-compacted particles; at higher temperatures, there is an increase in the rates of generation and retention of particles while compaction, sintering and oxidation of the particles in the layers are facilitated.

TL;DR: In this article, wear processes and mechanisms for wear transitions with sliding time and temperature during sliding of a nickel-based alloy, N80A, in oxygen at temperatures to 250°C are discussed.
