Friction and wear properties of Mo coatings on cast-iron substrates

Tribological behavior of Cr2O3 coatings as bearing materials

“…In acid environments, the amount of wear loss increases gradually by sliding time and also the applied higher load increases that amount. The affection of wear behavior by effects of environments and loads on wear behavior are similar to our former studies, which state that acidic environment could take wear products away Uyulgan et al, 2003). Corrosive environment supports debonding process of wear products from coating surface in earlier friction duration (first 1000 s) by corrosion effect and motion of corrosive liquid.…”

“…In acid environment, friction coefficient values become slightly high for 129 N than that of 109 N. There are lower friction coefficient values in acid environments if compare with that of in dry conditions. The similar friction behavior for dry and acid environments also appeared in former studies including dry and acidic conditions Ozdemir et al, 2003;Uyulgan et al, 2003;Bolelli et al, 2006). Fig.…”

Wear behaviour of thermal flame sprayed FeCr coatings on plain carbon steel substrate

“…More details regarding as wear experiments can be found in Refs. [1,6,10]. Wear loss and friction coefficients were evaluated for each sample by using the wear test machine.…”

Preparation of Low-Oxygen Mo Ingot by Optimizing Hydrogen Reduction and Subsequent Melting from MoO₃

“…Currently, molybdenum is widely used in stainless steel, machinery steel, and chemical products, and numerous studies aimed at investigating the use of molybdenum in high-value-added processes such as semiconductor manufacturing and liquid crystal display (LCD) sputtering are being conducted. 1,2) Normally, molybdenum metal is obtained from molybdenite as follows. Molybdenite is oxidation-roasted to obtain molybdenum trioxide, which is refined by heating to 1,273 K in air and subjected to sublimation refining or wet treatment, which involves the formation of ammonium molybdate.…”
