Owing to their combination of high hardness and increased fracture toughness, CrTaN coatings have recently gained increasing interest as suitable candidates for metal cutting applications. However, up now, the detailed mechanisms underlying oxidation this promising coating system are not thoroughly understood. Thus within work, evolution microstructure phase composition a cathodic arc evaporate...

iron-aluminum alloys are one of the most resistant alloys against sulfidation/oxidation environments with low oxygen partial pressures. the high sensitivity to hydrogen embrittlement is the main reason for decreasing of their room temperature ductility. there is a drop of strength above 600 c and their creep resistance is fairly weak. it is possible to increase ductility up to 15 percents and i...

Stainless steel powder was coated on mild steel substrate using plasma coating. The porous coating thus obtained was modified using laser irradiation. The oxidation behaviour of the plasma coated as well as laser treated material was studied in air at 1073 K. There was considerable decrease in oxidation rate of mild steel after plasma coating as expected. In addition the oxidation resistance im...
