The growing industrial automation across various sectors such as automotive, manufacturing, and electronics is expected to drive the demand. Furthermore, diamond like carbon coatings find widespread applications in devices subject to friction and wear including automotive components, cutting tools, and electronic components. Properties such as high hardness, chemical inertness, and low friction coefficient make diamond like carbon ideal for applications requiring protection from wear. Increasing investments by manufacturers to enhance productivity and reduce operational costs through automation are also expected to boost the market growth during the forecast period.

Growing demand from automotive industry

The automotive industry has been a major driving force contributing to the growth of the global diamond like carbon market. DLC films have found widespread use in various automotive components and parts owing to their unique properties such as high hardness, low friction coefficient, and excellent corrosion and wear resistance. Manufacturers have been increasingly adopting DLC coatings in products like engine bearings, gears, door handles, shock absorbers, and other moving parts that require protection against friction and wear over long usage. As DLC enables reducing lubricant needs and enhancing fuel efficiency, more automakers are turning to these coatings to meet stringent emission standards.

One key area where DLC demand is rising strongly is for coating various engine components. Given engines undergo grind stresses and friction during operation, DLC coatings help boost engine performance and lifetime. The coating offers a wear resistance comparable to diamond and acts as an effective barrier against corrosion caused by combustion residues. Leading automotive engine manufacturers have started using DLC for piston rings, cams, engine valves, and other high-pressure components to deliver improved power output and reduced emission levels. At the same time, demand is increasing from manufacturers of brake systems, where the low friction property of DLC plays a vital role in improving braking efficiency and durability. Automakers are also finding DLC useful for transmission components such as gears and bearings to minimize the abrasion of moving metal parts.

The rising sales of electric vehicles and hybrid models present new opportunities for DLC coatings. EV manufacturers adopt DLC films to enhance the efficiency of critical components like motors and batteries. The low friction of DLC helps extend the driving range of EVs while lowering production and maintenance costs. As governments worldwide implement stricter fuel-economy norms to curb emissions, automakers will progressively look at newer technologies like diamond-like carbon coatings that can boost energy efficiency throughout the vehicle. The growing preference for lightweight and high-performance vehicles will further accelerate the DLC demand from the auto sector in the coming years.

Increasing demand from medical devices industry

The medical devices industry presents a highly promising growth avenue for diamond-like carbon films. The biocompatibility, chemical inertness, and mechanical strength offered by DLC make it a preferred material for a variety of medical equipment. DLC coatings deliver resistance to corrosion and wear when in contact with body fluids, an essential requirement for implants and surgical tools. The coating eliminates reactions between device materials and tissues, preventing contamination that could infect patients. Leading medical device makers have thus significantly increased their adoption of DLC over the past decade.

Artificial joints and dental implants made of DLC-coated metals have superior load-bearing capabilities and longevity inside the body. As populations age globally, the demand for joint replacement surgeries is thriving internationally. By offering joints that can withstand decades of use without failure, DLC coated implants are revolutionizing orthopedic and dental procedures. Similarly, cardiovascular and neurological devices like stents, guidewires and catheter tubes rely on DLC films to deliver a smooth, bio-compatible surface. This has helped reduce infection risks and complication rates associated with such minimally invasive surgeries.

DLC is also getting widely used as a protective barrier on surgical tools and lab equipment that contact tissues. From biopsy forceps and scalpels to endoscopes and retractors, DLC provides scratch resistance and prevents reactions with bodily fluids. Given surgery tools are meant for single use mostly, the coating guarantees consistent performance of disposable devices at lower costs. Looking forward, as non-invasive diagnostic procedures gain prominence, more medical appliances ranging from lab-on-chip devices to imaging tools will adopt DLC for its bio-safety. With healthcare needs growing exponentially across the world, diamond-like carbon coatings will remain indispensable for manufacturing high-quality, long-lasting medical devices.
