What they work on
- Develop laser-based additive manufacturing settings for functionally graded austenitic and duplex stainless steel claddings on curved carbon steel, using both wire and powder feedstocks.
- Design multi-layer cladding strategies that achieve gradual composition change and epitaxial growth, where crystal structure carries across the cladding–substrate boundary, and link them to the claddings' metal microstructure.
- Measure the mechanical performance of cladded steel at multiple length scales using hardness, tensile and bending tests, including behavior under service loads.
- Quantify corrosion rates with electrochemical testing to predict service life, and use localized corrosion tests to assess how manufacturing defects weaken protection.
More about the research
Most of that cost comes from infrastructure, utilities and manufacturing, where cheap carbon steel is the workhorse material. Stainless steel resists corrosion much better. However, the alloying metals it needs (chromium, nickel and molybdenum) are costly and in limited supply, and making stainless steel affects the environment. A thin stainless layer on ordinary steel could give much of the protection with far less of these metals. Doing this well on curved shapes is the open challenge.
Why it matters
Stainless-clad carbon steel could extend the service life of rebar, pipes, vessels and containers. It could also cut maintenance and repair costs for infrastructure, utilities and manufacturing, while using far less scarce chromium, nickel and molybdenum than solid stainless steel. The findings could guide cladding strategies for many material systems and manufacturing techniques.
