Tungsten carbide coatings and method for producing the same |
摘要 |
<p>New tungsten carbides alloyed with fluorine in amounts up to 0.5 wt. % and possibly with fluorocarbon compositions are described. It is possible to produce them by means of a new process of chemical vapour deposition, in which tungsten hexafluoride, hydrogen and a carbon-containing gas are used. A specific feature of the new process is the preliminary thermal activation of the carbon-containing gas. The tungsten carbide coatings are deposited on construction materials and items made from them. They possess enhanced resistance to wear, corrosion and chemicals.</p> |
