At Western University’s Surface Science Western (SSW), researchers are advancing surface
analysis technology to solve a costly issue for the automotive industry: paint cratering. These
tiny but visible imperfections mar the smooth finish of vehicle paint and create expensive

setbacks for manufacturers aiming for high-quality standards. A dedicated team at SSW, led by seasoned researchers Heather Bloomfield and Heng-Yong Nie, uses cutting-edge surface analysis techniques to identify the root causes of these paint defects, transforming scientific insights into practical solutions. This collaborative effort includes the contributions of Mya Caverson, a summer student, who played a vital role in data sorting and analysis, helping the team streamline their findings and refine their approach. The project underscores SSW’s commitment to training the next generation of scientists while delivering real-world impact for
industry partners.


This research leverages time-of-flight secondary ion mass spectrometry (ToF-SIMS), an
advanced technique that enables highly precise analysis of the paint’s surface layer, probing the
outermost 1-3 nm to detect contaminants that may be invisible using traditional methods, and
providing crucial chemical insights. Unlike methods that penetrate deeper, ToF-SIMS allows
highly accurate surface analysis, enabling SSW researchers to detect minute contaminants that
cause significant disruptions. Findings, like a seasonal spike in paint cratering during colder
months, help manufacturers anticipate and prevent defects, ultimately improving production
quality.


SSW’s industry-centric approach is unique. Unlike labs staffed by rotating PhD students, SSW’s
team brings over 300 years of collective expertise, ensuring consistency in addressing complex
industrial challenges. Beyond paint cratering, they work closely with automotive leaders to solve
issues related to battery performance and electronic components. Known as a top surface
analysis facility, SSW delivers not just data, but actionable solutions aimed at cutting costs,
enhancing quality, and meeting the evolving demands of automotive and electronics industries.
The impact of this research extends beyond immediate cost savings. By identifying
contaminants early, SSW supports environmental sustainability. Fewer paint defects mean fewer
vehicles require rework, reducing waste and lowering the industry’s carbon footprint. With
growing demand for electric vehicles, SSW is also expanding its expertise to include battery
research, ensuring that science-driven solutions continue to address industry needs as the
sector shifts toward sustainability.


Through innovative techniques and a commitment to problem-solving, Surface Science Western
exemplifies Western University’s impact on global industries, delivering benefits from economic
efficiency to environmental responsibility. SSW is setting new standards in both surface science
and manufacturing quality—one crater-free vehicle at a time.
