Higher demand for lower emission

Driven by ever stricter emission legislations and rising energy prices, car and truck manufacturers are being forced to downsize and improve the efficiency of engines without compromising the performance levels and lifetimes of their vehicles.

The consequential increase of specific mechanical and thermal loads on components and the need to minimize the friction losses in mechanical assemblies lead to new materials and innovative surface treatment processes to reduce friction and wear. Plasma enhanced vacuum coating technology, PACVD, is one of the key contributors in adjusting to these demands.

Market trends

  • Downsizing of engines (fuel economy & emissions)
  • Hybrid cars; downsized combustion engine & electromotor
  • Start-Stop systems (oil film breaks)
  • Direct gasoline/diesel injection
  • Prolonged warranty periods

Tribobond™ 40 Series DLC coatings

Designed specifically for tribologically high loaded systems, the application of coatings with low-friction properties, such as Ionbond’s Tribobond™ 40 series DLC, opens new perspectives and technical solutions inside and outside the engine.

Tribobond™ DLC coatings increase the system efficiency and component lifetime dramatically. By incorporating them right from the beginning, the overall system cost can be held level or may even be reduced.

The enhanced tribological properties of Tribobond™ coatings not only protect the components from wear but also polish and protect the counter parts during in-running. As a result, the tribo system will remain in a low friction and wear condition.

High wear resistance and low friction

  • Matrix structure of diamond and graphite bindings
  • Coefficient of friction < 0.1 against steel (dry)
  • High hardness, up to 3.000 HV
  • Counterpart protection
  • Chemically inert, avoids cold welding
  • Excellent dry-lubricant properties
  • Deposition temperature of < 200 ˚C possible

Surface engineering

Depending on the specific requirements and load characteristics of a given application, the component coating consists of an adhesion layer, additional supporting layers, and a functional top layer.

The coating design, the choice of material and the thickness of each layer are optimized for function and economy.
