Introduction

Components and materials that are used in the automotive sector should exhibit high consistency and reliability since it is important that they function well in highly difficult operating environments. The performance data needed for optimization of such materials is provided by the NanoTest Vantage.

Requirements of the Automotive Sector

As far as commercial and domestic vehicles are concerned, it is essential to increase the lifetime and reliability of the components used. For this reason, there is a greater need for research and development in this area. The optimization of coatings and surface treatments for wear resistance is an important step to enable designing for improved efficiency combined with reliability. Meeting of these requirements is possible with the NanoTest Vantage.

NanoTest Vantage

The NanoTest Vantage system from Micro Materials combines several nanomechanical testing techniques into a single instrument. It can also operate at temperatures up to 750°C which means that it is being used increasingly to characterize high temperature and high performance materials and components such as airframes and avionics across the aerospace industry.

Unique Capabilities of the NanoTest Vantage

The instrument can conduct nanomechanical testing at temperatures up to 750°C that means that it is increasingly being used for measurement of mechanical properties of high performance materials for a broad range of applications in the automotive industry, from chassis to engine development.

Effect of Impact on PVD Coatings

PVD coatings such as TiAlN and AlCrN are mostly used as cutting tool coatings, but their excellent oxidation resistance and high hot hardness under extremes of loading, loading rate and temperature, have made them candidates for potential use in the automotive industry.

The Figure 3 shows high temperature impact in which the TiAlN coating is more resistant to fracture due to fatigue at 500ºC (blue curve) than the 25ºC (red curve).

Applications of NanoTest Vantage in Automotive Sector

The NanoTest is used by many internationally acclaimed automotive manufacturers, for the characterization and optimization of the following:

  • High performance paints
  • Polyurethanes
  • PVD Coatings
  • High performance coatings
  • Big end bearing shells
  • Fuel injectors
  • Piston alloys
  • Lightweight chassis materials
  • Composite tyres
  • Clutch linings, discs and bearings
  • Brake pads and discs
  • Fuel cells

Conclusions

The NanoTest Vantage has unique capabilities that ensure its use in the automotive sector. It is used for a wide range of applications owing to its capability of working at temperatures up to 750ºC where it can more accurately simulate real life operating conditions compared to ther room temperature tests.
