What is DLC?
DLC (Diamond Like Carbon) is a category or classification for a specific family of thin-film coatings.This group of coatings is typically used on critical wear components to drastically improve durability,decrease friction and improve the general function of certain components; extrusion tooling, gears,weapon components, actuators, etc.
How does one “bake” a DLC coating?
DLC can be achieved through different methods including PVD (physical vapor deposition), CVD(chemical vapor deposition) etc. UPT uses a Plasma enhanced Chemical Vapor Deposition Process(PeCVD). One of the benefits of this unique, “hybrid”, process is that we achieve a DLC throughlower than average processing temperatures, 350 F, which is good news for a lot of materials that have lower annealing temperatures.
Technical graph showing how DLC is categorized.
All this graph means is that DLC must have a certain amount of Sp2, Sp3 and H bonds. I prefer the“cake” approach to understanding this.
