Expanite, the surface hardening specialist, has consulted and advised the students at the RennTeam Uni Stuttgart in identifying and solving some of their challenges with wear on the titanium parts in their racing car.
The Rennteam Uni Stuttgart takes part in the Formula Student racing series, a competition for young engineers across Europe, as well as being involved in other international competitions.
The young constructors of the Rennteam Uni Stuttgart are constantly striving to optimize the construction process including the use of materials and spend almost all their time in constructing and testing the cars to prepare for competitions.
To increase the performance including lowering the weight of the race car, the students changed some of the parts to titanium but were faced with problems related to wear parts due to low surface hardness and they decided to contact Expanite for possible solutions.
The Expanite material experts proposed to surface harden the critical titanium parts including parts of the power train, sitting between the differential and the drive shaft with the ExpaniteHard-Ti process. The Expanite hardening makes the use of light-weight titanium parts possible therefore resulting in increased efficiency and significant weight reduction.
