Any place you have wear is a candidate for a thin-film ceramic coating. While the use of coatings on parts such as turbine engine components is increasing, cutting tools use the bulk of coatings. Coatings have certainly proved their worth, increasing tool life from 2 to 10 times when compared to uncoated tools. Newer coatings are achieving ever-higher maximum operating temperatures and hardness, and are increasingly tuned for specific properties, such as abrasive wear or toughness. The first choice in thin-film coatings decades ago was TiN, the familiar yellow-gold coating still often used today. In the last five to 10 years, a marked reduction in the costs of coatings due to shorter processing times has been seen. Also, the move to more multilayered coatings takes advantage of the strengths of different coatings, reducing the need for lubricants.
