Xueyuan Nie, a professor of mechanical, automotive and materials engineering, is proud and humbled as a recipient of an award of excellence from an industry group.
Dr. Nie was honoured as a “key collaborator” by the Auto/Steel Partnership, a consortium of steel-producing companies and automakers. The award recognizes an outside contractor whose contributions to a project prove valuable in overcoming challenges.
Nie recalls helping Chrysler address a challenge in stamping advanced high-strength steels.
“The existing tooling dies could only stamp around 100 parts and soon failed,” he says.
He proposed a duplex treatment which added a hard ceramic layer to the dies.
“To be honest, some of the team members didn't believe this approach would work since the coating was only a few microns thick. It was hard to believe such a thin ceramic layer could withstand thousand tons of stamping forces.”
The surface engineering method he proposed has become an industry standard for preparing stamping tooling dies.
