Abstract
Kemijsko taloženje uz pomoć plazme, PACVD koristi se za nanošenje izuzetno glatkih, dobro prijanjajućih prevlaka sličnih dijamantima (DLC) u okruženju visokog vakuuma na temperaturama ispod 200 °C. Za razliku od PVD procesa, nije potrebna katoda. Osim toga, u nekim slučajevima dijelove nije potrebno rotirati u komori. PACVD prevlake su amorfne strukture i sadrže oko 70% sp3 veza, što rezultira visokom tvrdoćom prevlaka. Nanesene DLC prevlake, otporne na trošenje, dizajnirane su za specifična okruženja primjene. Postupak može nanijeti prevlake na širok raspon podloga, uključujući i vodljive i izolacijske materijale. Uobičajene primjene uključuju komponente motora i strojeva, dijelove crpki, medicinske uređaje i ukrasne predmete. Krajnji korisnici kreću se od automobilske i zrakoplovne industrije, do sektora energije, lijekova i robe široke potrošnje. PACVD postupak kombinira PVD i CVD karakteristike s glavnim prednostima: veliki izbor u pogledu materijala podloge, kratko vrijeme ciklusa/visoka produktivnost, niske do umjerene temperature nanošenja - uz zadržavanje njihove geometrije i tolerancije, izvrsna ujednačenost prevlake na raznim geometrijama, ekološki prihvatljiv proces te je također moguće prevlačenje određenih unutarnjih promjera. Trenutni trend, posebno za automobilske komponente, su prevlake koji se sastoje od kombinacije PVD i PACVD, pri čemu PVD obično služi kao osnovni sloj za podupiranje PACVD završnog sloja. Stoga većina moderne opreme za prevlačenje ima sposobnost obaviti oba procesa.
Abstract (english)
Plasma - assisted Chemical Vapour Deposition, PACVD is used to apply extremely smooth, well - bonded diamond - like coatings (DLC) in a high vacuum environment at temperatures below 200 °C. Unlike the PVD process, cathode isn't required. In addition, in some cases it is not necessary to rotate the parts in the chamber. PACVD coatings are amorphous structures and contain about 70% sp3 bonds, which gives the coatings high hardness. The low - friction applied DLC coatings are designed for specific application environments. The process can apply coatings to a wide range of substrates, including conductive and insulating materials. They typically use engine and machine components, pump parts, medical devices, and decorative items. End - users range from the automotive and aerospace industries, to the energy, medicines and consumer goods sectors. PACVD combines PVD and CVD characteristics with the main advantages: large choice in substrate material, short cycle time/high productivity, low to moderate coating temperatures while maintaining their geometry and tolerance, excellent coating uniformity on various geometries, environmentally friendly process and also possible coating certain internal diameters. The current trend, especially for automotive components, are coatings consisting of a combination of PVD and PACVD, with PVD typically serving as the base layer to support the PACVD finish. Therefore, most modern coating equipment has the ability to perform both processes.
