C

:
See chemical vapour deposition.
flag CVD

D

:
Loss of carbon from a steel surface to a level well below that of the core, often as the result of prolonged high temperature exposure in an oxidising atmosphere.
Hungary flag dekarbonizáció
:
Any coating primarily produced to enhance its appearance. For example see gilding.
Hungary flag Dekorációs bevonatolás
:

Any methods that achieve the removal of organic compounds, such as grease or oil, from the surface of an object, e.g., see vapour degreasing.

Hungary flag zsírtalanítás

:

A synonym for coating (noun), but also referring to any adherent surface solid formed, for example, as a result of wear or corrosion.

Hungary flag fémbevonat

:

The act of laying down a metallic or non-metallic layer onto a substrate.   There ae numerous deposition techniques; these include electrodeposition, plasma spraying, PVD and CVD.

Hungary flag Galván úton bevonatol

:

Any process used for the purpose of removing the scale from heavily oxidised metal.  This can be achieved by mechanical (abrasive blasting, tumbling, brushing) or chemical means (alkaline descaling, acid descaling (pickling) or salt bath descaling).

Hungary flag revétlenítés

:

An engineered surface with optimal constitution, treatment depth and properties, designed with intent for specific application(s).

Hungary flag Tervezői felület

:

Diamond coatings can be deposited by many methods.  Presently, the most favoured technique is microwave plasma CVD.   Diamond coatings are crystalline and are usually characterised by a combination of methods which include, Raman spectroscopy, X-ray diffraction and surface morphology.    Also see hot filament CVD

Hungary flag Gyémánt bevonatok

:

A very hard (≈3000-4000 kg/mm2) carbon coating with little or no crystallinity (amorphouis).    Initially such coatings proved unsatisfactory for tribological protection because of poor substrate adhesion and unfavourable residual stress.  Some recent progress has been made whereby appropriate sub-layers of transition metal carbides and nitrides are deposited prior to deposition of a DLC.   This is particularly important when deposity DLC onto metallic substrates.  DLC's can be deposited by sputter deposition or plasma assisted CVD

Hungary flag Gyémánt-szerű bevonatok (DLC)
