High Performance Ceramic Coatings Markets and Technologies
The North American market for high performance ceramic coatings was worth more than $1.1 billion in 2012. This figure is expected to increase to $1.2 billion in 2013 and nearly $1.7 billion by 2018, with a projected five-year compound annual growth rate (CAGR) of 6.6%.
Ceramic coatings constitute a large family of materials with quite diverse compositions and properties. They include compositions based on alumina, alumina–magnesia, chromia, hafnia, silica, silicon carbide, titania and zirconia. Ceramic coatings are generally applied to metal or metallic alloy components or to ceramic components.
High-performance ceramic coatings are a special class of ceramics because of their form and the preparation techniques required. However, their uses are diverse, and they exploit a wide range of unique and desirable properties of various bulk ceramics. Ceramic coatings are generally used for wear- (or erosion-), corrosion- and high temperature-resistant applications. All ceramic coatings deliver some level of performance in each of the three major areas listed above.
The availability and commercialization of high-performance coatings have already changed the internal specification patterns of certain industries such as cutting tool inserts. The useful life of coated inserts is many times longer than the life of uncoated inserts. This, in turn, has reduced the cost of cutting tool inserts and at the same time increased productivity. Similarly, use of ceramic coated components for aircraft turbine engines has resulted in construction of large aircraft. Currently, auto enthusiasts are coating certain components to improve auto engine performance. In addition, ceramic coatings have made it possible for certain large machine components to be repaired in situ.
