Chemical vapor deposition (CVD) is one of the most common processes used to coat almost any metallic or ceramic compound, including elements, metals, and their alloys and intermetallic compounds. The CVD process involves depositing a solid material from a gaseous phase; this is achieved by means of a chemical reaction between volatile precursors and the surface of the materials to be coated. As the precursor gases pass over the surface of the heated substrate, the resulting chemical reaction forms a solid phase which is deposited onto the substrate. The substrate temperature is critical and can influence the occurrence of different reactions.

There are several types of CVD process, including atmospheric pressure chemical vapor deposition, metal-organic chemical vapor deposition, low-pressure chemical vapor deposition, laser chemical vapor deposition, photochemical vapor deposition, chemical vapor infiltration, chemical beam epitaxy, plasma-assisted chemical vapor deposition, and plasma-enhanced chemical vapor deposition.

1.Do you know the characteristics of CVD coating types?

Characteristics of CVD Coating Turning Inserts Types:

TiN Coatings:

• Excellent build-up edge resistance

• Excellent on gummy materials

• Excellent for threading and cutoff operations

• Makes it easy to identify what insert corners have

been used

• Effective at lower speeds

TiC Coatings:

• Excellent wear resistance

• Effective at medium speeds

• Excellent on abrasive materials

Al203 Coatings:

2.The advantage of CVD coated turning inserts?

Chemical Vapor Deposition (CVD) Coatings

CVD-coated inserts work well in turning, milling and drilling applications involving ferrous materials. In fact, CVD-coated inserts are recommended over PVD-coated inserts for turning, milling or drilling steels and cast irons.
