Technical Ceramics Meet Highest Requirements

The requirements on components in the automotive industry are particularly high: manufacturers are looking for reliable suppliers who are capable of consistently delivering top quality components in large volumes. Furthermore, certifications such as ISO 9001 or IATF16949 are required - which Bosch holds as a matter of course. Our customers are looking both for components that can cope with the challenging conditions in the engine bay and for material that can be used for alternative types of powertrains such as fuel cells.

Why Advanced Ceramics?

Resistance to Wear and high pressures

Technical Ceramics show hardly any wear even with high mechanical stress.

Temperature Resistance

Technical Ceramics are resistant to the high temperatures generated in the combustion engine.

Chemical Resistance / Resistance to Corrosion

Technical Ceramics remain stable when in contact with harsh substances such as coolants and fuel.

Case Study: Contact holder

The lambda sensor is a common component found in the exhaust system of combustion engines. It measures the oxygen content and can thus optimally control the combustion. The sensor is made of many components, some of which are made of ceramics. A clamp is needed to fix the sensor and to provide the contact between the sensor and the cable. This component must have high electrical insulation properties in order to avoid false measurement results. Only Technical Ceramics are worth considering when talking about a possible material that resists high temperatures and vibrations during driving. Only Technical Ceramics combine temperature resistance with electrical insulation.

Stability at High Temperatures

The Long Lifespan of Technical Ceramics Stands Out

When faced with high temperatures, the excellent strength properties of Technical Ceramics can be seen in the strength chart. There is no other material that is as resistant to bending, even at temperatures far exceeding 1000°C. This high-performance material is absolutely suitable in combination with additional influencing factors such as high pressure or corrosive fluids. Not to forget the low thermal expansion: ceramics hardly expand with strong heat and are resistant to high temperature variations. The lifespan of engine components is crucial: if a component breaks down too soon, the customer may face high repair costs.
