Ultra-Short Pulsed Laser Deposition Sets New Standards for Diamond-Like Coatings
Finnish coating technology specialist Picodeon has developed a technique for depositing diamond-like films onto a wide range of substrates using its patented ultra-short pulsed laser deposition (US PLD) technology.
Diamond-like coatings create super-hard surfaces (greater than 40 Gpa) with a low coefficient of friction and excellent coating adhesion. The US PLD deposition process uses a high laser pulse repetition rate and fan-shaped plasma bloom, which enables high production rates and makes the industrial coating of large surfaces at film thicknesses down to nano-scale feasible. Pulse duration is in the range of picoseconds, typically < 10 picoseconds.
