Diamond-Like Carbon (DLC) has properties of diamond such as high hardness, low friction, resistance to wear, chemical inertness, biological compatibility, electrical insulation, optical transparency, and smoothness. DLC coating is acquiring interest from the past two decades because of its fascinating and commercially essential coating material for various industrial applications. It is used in various industrial applications such as critical engine parts, mechanical face seals, scratch-resistant glasses, invasive and implantable medical devices, micro-electro-mechanical systems, razor blades, and magnetic hard discs. The presence of few elemental species such as hydrogen, nitrogen, sulphur, silicon, titanium, and fluorine are an added advantage to the properties of DLC.
According to the study “Asia Diamond-Like Carbon Coating Industry Situation and Prospects Research report”, DLC possesses tribological properties that depend upon the micro-structure, hydrogen present and ratio of sp2 to sp3 carbon atoms. Pure Diamond-Like Carbon (pure DLC) and mixed Diamond-Like Carbon (mixed DLC) are the two types of Diamond-Like Carbon (DLC). The various deposition methods used in the production DLC are ion beam, sputtering, cathodic arc, pulsed laser deposition, and plasma enhanced chemical vapour deposition. Diamond-Like Carbon (DLC) coatings are used in automotive engine components such as diesel fuel injectors, automotive tappets, rocker arms, differential gears, valve lifters, wrist pins, and door hinges. DLC coatings help increase the life time of automotive engine components by decreasing the coefficient of friction. Additionally, the high load bearing properties of DLC coatings make it an ideal choice for improving the performance of engineered components which prevent leaching of metallic ions in the automotive body parts. It was observed that there is an increase in demand for advanced coatings with high abrasion resistance that are the major drivers in Diamond-Like Carbon (DLC) coating market in Asia.
There is a huge demand for Diamond-Like Carbon (DLC) coatings in medical industry due to high biocompatibility. Biomedical components demand for DLC coatings with exceptionally hard, low friction, and bio-inert characteristics. Diamond-Like Carbon (DLC) coatings in bio-medical sector are used in orthopaedics, cardiovascular components, guide wires, razor blades manufacture, skin wrinkling treatments and others due to its biocompatible nature. Geographically, Asia Diamond-Like Carbon Coating Market is spread across China, India, Korea, Japan, Saudi Arabia and other regions. The leading manufacturers of Asia Diamond-Like Carbon Coating Market are Oerlikon Balzers, IHI Group, CemeCon, Morgan Advanced Materials, Miba Group (Teer Coatings), Acree Technologies, IBC Coatings Technologies, Techmetals, Calico Coatings, Stararc Coating and Creating Nano Technologies.
Asian Diamond-Like Carbon (DLC) coating manufacturers are focusing on the production of hydrogen-free Diamond-Like Carbon (DLC) coating that can be employed in automotive and biomedical applications due to their superior abrasion and wear resistance. Hydrogen-free DLC coatings improve binding with engine oil and result in the formation of a firm ultra-low friction film when special oil additives are added in an automobile. Advanced technologies such as plasma enhanced Carbon Vapour Deposition (CVD) and pulsed laser deposition will surely propel the applications of Diamond-Like Carbon (DLC) coatings in Asian markets.
Micro-Electro-Mechanical Systems (MEMS) technology in electronics sector is expected to witness a steady growth in Diamond-Like Carbon (DLC) coatings market in Asia. Diamond-Like Carbon (DLC) coatings are made up of carbon atoms that may combine with oxygen and emit carbon dioxide intensifying global warming effect. Implementation of stringent regulations on carbon dioxide emissions is likely to hamper the development in Diamond-Like Carbon (DLC) coatings market over the next few years. Additionally, poor adhesion of Diamond-Like Carbon (DLC) coatings onto substrates may adversely affect the Diamond-Like Carbon (DLC) coatings market. With more R&D happening in Diamond-Like Carbon (DLC) coatings market, ultrathin layer coating technologies is anticipated to help the market overcome few of the challenges.
Medical device manufacturers are focusing on adopting greener engineering technologies such as Diamond-Like Carbon (DLC) coatings due to biocompatible properties and can be used in a wide range of temperatures. Introduction of self-healing Diamond-Like Carbon (DLC) coatings, which produces ultra-thin film with high performance characteristics, will surely drive the market in Asia over the next few years.
