Abstract

Hard coatings of tungsten carbides have been obtained by the deposition of tungsten thin layers, on steel substrates (containing 0.5% to 0.75 wt.carbon), according to the cathodic magnetron sputtering held at temperature of 650°C. It is established by X-rays diffraction that, in thetemperature range 650-900°C, no formation of tungsten carbides was observed… (More)
