High-performance Ceramic Coatings Market Receives Boost from Automotive, Aerospace Industries

High-performance ceramic coatings (HPCC) are used to offer protection against corrosion, wear and tear, and temperature attenuations. These coatings can sustain temperature as high as 15000°C. Other than this, resistance against thermal shock and providing protection to vulnerable components are the other advantages of these coatings. Composed of oxides, nitrides, carbides, yittria, alumina, and zirconium, HPCCs that are essentially thin layered are one of the most crucial components of the advanced ceramics industry.
The utilization of HPCC is seen across several industry sectors such as aerospace, automotive, and semiconductor to name a few. Due to the high usability of these coatings for machinery components and semiconductor chips, the global market for high-performance ceramic coatings is poised for excellent growth prospects in the forthcoming years. The market, expanding at a CAGR of 7.0% from 2014 to 2020, will reach a valuation of US$9.07 bn by 2020 increasing from US$5.68 bn in 2013, says Transparency Market Research.

Wartime Needs brought in First Use of Ceramic Coatings

The utilization of ceramic coatings dates back to World War I. It is the Germans who are credited with the first utilization of ceramics in armor, wherein hard-faced enamel coatings were applied on tanks for protection against small arms and shell fragments. Later, the imminent shortage of a number of essential materials, such as nickel and chromium due to their increased utilization as alloy constituents and prohibitions in the normal importation of these ores led the National Bureau of Standards in the U.S. to undertake a program to alleviate this contingency. Ceramic-coated steel was the most suitable replacement for nickel-chromium alloys for high-temperature applications.

To explain this, the exhaust manifolds of some automobile engines coated with conventional glossy porcelain enamel were tested for their current temperature handling limit, as well as the development of a newer ceramic coating suitable for high-temperature applications. The development work performed at the Bureau in 1942 laid down specifications of some of the properties that are vitally important for these coatings:
  • These should bond well to the metal
  • These coating need to be thin – reducing weight and minimizing the chances of chipping and cracking due to mishandling are the reasons for this
  • These coating should not exhibit properties of ‘reboil’ – a phenomenon wherein gas bubbles are observed if porcelain-enameled steel or iron is reheated after the first use
  • These should offer protection against oxidation to the metal if subject to high temperatures for prolonged periods
  • These coating should exhibit high resistance to thermal shock and temperature gradients
Technological Potential Aids High-performance Ceramic Coatings Market

The progression of the global high-performance ceramic coatings market is attributed to several factors, the availability of several coating technologies being an integral reason. These coating technologies include: thermal spray coatings, chemical vapor deposition (CVD), physical vapor deposition (PVD), and sol-gel processing among others. Amongst these, the thermal spray technology dominated the global high-performance ceramic coatings market in 2013, followed by CVD with a share close to 16% in the global market. However, in the coming years, PVD technology will emerge as the dominant technology in the global high-performance ceramic coatings market.
