To ensure DLC coatings can withstand real-world mechanical stresses, Micro Materials employs patented nano-impact testing—a high-strain rate technique that mimics the severe dynamic loading conditions found in automotive engines, aerospace applications, and high-speed cutting tools. Unlike conventional nanoindentation tests, which only assess initial crack resistance, nano-impact testing evaluates coating durability under continuous stress cycles. This provides valuable insights into: - Toughness – The ability to resist crack initiation under impact. - Damage Tolerance – The ability to slow down or prevent crack propagation. - Fatigue Resistance – The longevity of the coating under repetitive high-load conditions.
