case study: high-performance coatings for downsizing in engine manufacturing
Engine downsizing places high demands on the components used. Turbocharger and compressor impellers are becoming smaller and lighter, yet they must still deliver comparable performance and reliably withstand high mechanical, thermal, and abrasive stresses.
With the DURNI-COAT® coating, Aalberts surface technologies offers a proven solution for protecting heavily stressed engine components.
the challenge
As engines become more compact, the stresses on individual components increase. Turbocharger and compressor impellers, in particular, must function reliably even under demanding operating conditions.
For example, small dust and dirt particles can strike the compressor blades. The resulting erosion and wear can damage the surface and, over time, impair the function and service life of the components.
Therefore, coatings are needed that reliably protect components against various stresses without compromising their function.
requirements
The following properties are particularly important for use in downsizing engine design:
- High surface hardness
- Excellent wear resistance
- High erosion resistance
- Excellent corrosion resistance
- High thermal resistance
- Optimal sliding behavior
our solution: DURNI-COAT®
For this application, we rely on our DURNI-COAT® chemical nickel plating process.
Chemical nickel plating has been in use since the 1950s and is characterized, among other things, by a uniform coating structure, high hardness, and good resistance to wear, erosion, and corrosion.
Coating the relevant surfaces of compressor and turbocharger components creates a durable protective layer that reliably shields the components from the stresses they encounter.
the benefits at a glance
DURNI-COAT® offers the following properties, among others:
- High wear resistance: Protection against abrasive wear and mechanical stress
- Erosion resistance: Protection of surfaces against the effects of particles
- Corrosion resistance: Reliable protection against corrosive influences
- High hardness: Durable surface even under high stress
- Optimal sliding behavior: Supports reliable component function
- Thermomechanical resilience: Suitable for demanding operating conditions
the result
The DURNI-COAT® coating increases the resistance of the coated components to wear, erosion, and corrosion. This allows turbocharger and compressor impellers to be used reliably even under the high loads of modern, downsized engines.
The advantages at a glance:
- Higher wear resistance
- Improved protection against particle erosion
- Increased resistance to thermomechanical stress
- Potentially extended component service life
- Reliable operation even under demanding conditions
why DURNI-COAT®?
With decades of experience in surface technology, Aalberts surface technologies develops and implements coating solutions for components subjected to extreme stress.
DURNI-COAT® combines high hardness with resistance to wear, erosion, and corrosion, making it ideal for applications where component surfaces are continuously exposed to high stresses.
Aalberts surface technologies thus offers a high-performance and scalable coating solution for demanding applications in modern engine manufacturing.
