1. More operating cycles
Lengthening the service life of micro-tools
In the electronics and watchmaking industries, micro-tools are essential elements of the manufacturing process. After only 10 to 20 operating cycles, drills with a diameter of as little as 0.1 mm will become worn. Oerlikon’s aluminum titanium nitride and aluminum chromium nitride coatings not only increase the precision of the drills but also lengthen the service life to up to 1 000 operating cycles with the same tool.
2. A clean print
Ensuring precisely metered ink for clean prints
A messy and dirty print happens when ink is not precisely metered to the printing plate for flexographic printing. It is also costly, as it ruins the entire print run. To ensure the quality of the anilox rolls, plasma-sprayed chromium oxide is homogenously coated on them, ensuring successful laser engraving of the ink-metering cells while also protecting the anilox roll from the corrosive effects of the ink.
3. Ensuring performance
Protecting turbine blades from erosive materials
Kaplan water turbines employ an adjustable propeller that allows the turbine to operate efficiently in various flow conditions. As the turbine blades are exposed to erosive materials such as sands, silts and gravels, turbine efficiency is reduced. The blades are also subjected to fluid erosion and cavitation. With Oerlikon’s High Velocity Oxygen Fuel (HVOF) materials, the blades are protected, significantly extending the blades’ service life while ensuring high turbine efficiency and maintaining the expected turbine power output.
4. Supporting recovery
Improving patient outcomes with surgical implant coatings
Medical implants can trigger inflammation or infection, and are often rejected by the recipient. Bone implants are a particular challenge as they typically do not fuse quickly enough, reducing the stability of the implant and slowing down a patient’s healing process. Titanium implants coated with a silver-containing layer can prevent inflammation, stop the body from rejecting the implant and reduce the need for secondary operations. In addition, titanium bone implants can be given a mineral coating whose biocompatible, porous structure promotes bone growth and speeds up a stable connection between implant and bone.
5. Saving 50 % of costs
Coating turbochargers for maximum efficiency at a lower cost
For car manufacturers, turbochargers are instrumental in improving vehicle efficiency and cutting CO2 emissions. Their performance can be considerably enhanced with coating solutions. Oerlikon’s abradable coatings for clearance control increase efficiency and cut the cost in half compared to conventional coatings. This makes turbochargers attractively priced for the mass market.
6. 30 % reduction of oil consumption
Reducing oil consumption by reinventing cylinder surfaces
Car engines are becoming lighter, more efficient and more environmentally friendly, but they must run at high temperatures to burn fuel more efficiently, placing added stress on conventional engine parts. By applying a special coating to the cylinder bores, Oerlikon’s surface technology reduces friction and makes them more heat-resistant. The result is a 30 % reduction in oil consumption and a fuel saving in the range of 2 %.
The new Porsche Panamera is just one example how Oerlikon’s successful customers rely on this coating technology.
