Investigation of tungsten dc vacuum arc characteristics. Technological application

We also investigated some legitimacies of changes in element composition, adhesion strength, hardness, morphology and structure of W coatings formed from plasma of a dc vacuum arc discharge (VAD) depending on regimes of coating deposition. It is shown that use of Ti plasma for creating a thick transition and damping layer under the regime of plasma immersion ion implantation and coating deposition under intensive ion mixing allows to increase adhesion strength of W coatings by several times.
