Gamma titanium aluminide (γ‐TiAl) alloys are attractive lightweight materials for high‐temperature structural applications. However, their limited wear resistance and susceptibility to localized corrosion restrict wider deployment. Ceramic reinforcement offers a potential route to performance enhancement, but the combined tribological and ...

REPAIR OF A DAMAGED TURBOCHARGER
he turbocharger is among the highest quality assemblies for modern internal combustion engines. Its contribution to engine operation is immeasurable – it increases the power output of the engine while indirectly reducing fuel consumption. Like all devices, turbochargers require quality maintenance as they are susceptible to failure.

Integrating powertrain electrification with efficient engines using low‐carbon fuels like natural gas (NG) improves energy conversion efficiency and mitigates greenhouse gas (GHG) emissions in heavy‐duty (HD) trucks. High‐pressure direct injection (HPDI) NG engines, using less than 5% diesel (energy basis) as pilot fuel, offer diesel‐like efficiency ...
