Diamond-like Carbon (DLC) Market Size, Share | Global Industry Report, 2025

Diamond-like carbon or commonly known as DLC, includes carbon items with spbonding. It contains various useful properties including chemical inertness, mechanical hardness, and optical transparency. DLC is gaining the attention of various industries due to its widely applicable properties and continues to attract investments worldwide through research.

Currently it is in heavy demand for razor blades, magnetic hard disks, invasive and implantable medical devices, scratch-resistant glasses, and mechanical face seals. DLC includes various chemical elements such as hydrogen, sulphur, silicon, fluorine and titanium. This makes it an essential ingredient in manufacturing for a wide variety of applications. 

DLC’s micro-structures make up for its tribological properties. These micro-structures include the volume of hydrogen present, and sp2 to sp3 carbon atoms ratio.  There are two main types of DLCs in the market. These two types are pure DLC and mixed DLC. 

Growing demand in automotive and pharmaceutical industry is expected to drive the diamond-like carbon market 

The global diamond-like carbon market is expected to be driven by growing demand for the product in automotive engine components. DLC coatings serve a useful purpose in automotive tappets, differential gears, diesel fuel injectors, valve lifters, door hinges, and wrist pins. Friction can reduce the life of these important automotive components as well as reduce their usefulness with rusting.

DLC coating provides an important protective shield and often provide appealing décor in a cost-effective manner. Additionally, DLC coating improves lubrication by reducing friction. Consequently, it improves the efficiency of vehicles for all stakeholders. Advancements in DLC coating including high abrasion resistance is expected to further boost the Diamond-like Carbon market during the forecast period.

Due to DLC’s high biocompatibility, the demand for it is also high in the medical industry. It is expected to become a key factor for driving growth in the diamond-like carbon market. The DLC offers various benefits to the medical industry including low friction, bio-inert characteristics and, exceptional brittleness. These qualities help stop the leakage of metallic ions to body parts.

Hence, DLC is extremely helpful in orthopedics surgeries as well as regular therapy. It also offers various benefits to cardiovascular treatments, guide wires, etc. These reasons are expected to help the diamond-like carbon market growth during the forecast period.

Emission of carbon dioxide is reportedly a major reason for global warming. DLC coating involves the layer of carbon atoms. It can combine with oxygen and release carbon dioxide in the atmosphere. The stringent regulations governing the automotive industry and keeping carbon dioxide in check can hamper growth of the diamond-like carbon market.

Lack of strong adhesive abilities of DLC can further contribute to the impact on the market in Europe and North America. Major players situated in these regions are investing in ultrathin layer coating technologies. Its growing advancement can bring good news for the market during the forecast period.

Other highly advanced technique are also undergoing innovation in the diamond-like carbon market. These include plasma assisted chemical vapour deposition and pulsed laser deposition. Additionally, self-healing DLC, which manufactures ultra-thin film with high performance characteristics, is expected to boost the market growth further during the forecast period.
