Diamond-Like Carbon (DLC): Tough, Thin, and Versatile

Introduction:

Diamond-like carbon (DLC) is a material that looks and behaves a lot like diamond.

Diamond-like carbon (DLC) is

1. Extremely hard
2. Smooth, and
3. Resistant to wear

How is DLC Produced?

DLC is made by depositing carbon atoms onto a surface in thin layers using methods like

• Chemical vapor deposition (CVD) or
• Physical vapor deposition (PVD)

These processes happen in special chambers at low pressures where gases are turned into solid coatings under controlled conditions (temperature, control gas, carrier gas, substrate, etc.)

How is DLC used for?

DLC is used across many fields

1. Automotive – Parts like gears, bearings, and fuel systems get a DLC coating to reduce friction and extend their life
2. Healthcare – Doctors use surgical tools and implants coated with DLC because it is biocompatible and resists body fluids.
3. Electronics – It protects sensitive parts like hard drive disks and smartphone screens from scratches
4. Apparel & Accessories – Even luxury watches and jewellery use DLC for its elegant look and durability

Conclusion:

DLC coatings help products last longer, work better, and look newer. DLC is an amazing example of how advanced materials can quietly improve the things we use every day.
