Název v původním jazyce

Structure, mechanical properties and tribology of W-N and W-O coatings

Popis výsledku v původním jazyce

We are presenting here a summary of our recent work on tungsten nitride (nitrogen content 0-58 at.%) and tungsten oxide (oxygen content 0-75 at.%) coatings deposited by reactive magnetron sputtering. Our aim has been the analysis of the connection of fundamental properties of these films, such as chemical composition, structure, hardness, Young's modulus and residual stress, with their tribological properties - friction coefficient and wear rate. We have been focussed mainly on the description of the dominant wear mechanisms influencing the tribological properties. The tribological tests have been carried out both at room and elevated temperature; the temperature was increased in steps until immediate coatings failure. The tungsten nitride coating withthe "worst" parameters generally considered as vital for high wear resistance, such as hardness, were considered to have the best tribological performance.
