EFFECT OF IMPULSE BIAS POTENTIAL TO FORMATION OF WEAR-PROOF COATING DEPOSITED FROM PLASMA FLUXES
Journal Title: Scientific Journals of Silesian University of Technology. Series Transport - Year 2016, Vol 2016, Issue 92
Abstract
Plasma-based technology is used to deposit a wear-proof nanostructured coating on plunger tappets of pump of aviation oil system block, which allows increasing the life of the parts up to 3–5 times. For the nanostructured coatings, which are formed at the impulse bias supply, the electric field strength is 103-104 times greater than for the microstructured coatings. It results in significant change of activation energy of the process of strong bond formation in the growing coating, which makes it possible to obtain high qualitative characteristics of the coating
