摘要: Abstract Ferrite (pure α-Fe) and austenite (AISI 304 stainless steel) discs were implanted to doses ranging from 1 × 10 17 18 O 2 cm -2 at temperatures 90 500 °C tested using an oscillating pin-on-disc wear tester. Mossbauer spectroscopy, X-ray diffraction Auger electron spectroscopy used characterize the microstructures compositions of layers. Although oxygen implantation reduces rates both steel constituents all temperatures, lowest are observed in α-Fe lower elevated temperatures. Ranked most least resistant, oxides ferrite FeO, Fe 3 4 . When implanted, hematite-like oxide is formed a magnetite-like begins appear addition (500 430 ). The when 400 induces greatest load for transition mild severe adhesive (approximately 300 times unimplanted discs).
