Abstract:
A high temperature substrate coating to mitigate liquid metal embrittlement (LME) cracking in automobile vehicles includes a substrate. A coating is disposed on the substrate, the coating being one of a zinc-based material and an aluminum-based material, with the coating having a melting point of at least 500° C.
