Prof. Richard Chromik

Research Associate and Post-Docs

 

Sima was born and raised in Azerbaijan province, Iran. She completed her bachelor’s degree on Materials Science and Engineering with a focus on Extractive Metallurgy. She attended Tarbiat Modares University for a master program, where she worked on surface modification and tribology of cast Al alloys and hybrid Al-SiC-MoS2 composite coatings. In 2014, she started her PhD studies under the supervision of Prof. Chromik. Her PhD research project involved understanding of cold spray deposition mechanism of Ni-WC composite coatings and their sliding and erosive wear behaviour. She defended her PhD dissertation in June 2018 and started her postdoctoral fellowship. Her primary work was on surface engineering of advanced self-lubricating composite coatings as well as lifecycle improvement of super-abrasive composite coatings. Sima is now working as Research Associate in Surface Engineering and Coating Tribology Laboratory. In her spare time, Sima enjoys reading, listening to music and swimming.

Vamsi was born and brought up in India. He received his undergraduate degree in Mechanical Engineering from Osmania University (India) and M.S. in Materials Engineering from Indian Institute of Technology Madras (India). During his master’s, he worked on the electrodeposition of Ni-W alloy coatings and evaluated their electrochemical and tribological properties. As a side project he was involved in the fabrication Ni-Mo and Ni-W-SiC nanocomposite coatings. The work done for his master’s thesis resulted in two first author publications. To peruse his Ph.D., Vamsi joined Prof. Chromik’s research group in September 2015, and started working on the tribology of metal matrix composites fabricated using cold spray additive manufacturing process. For his Ph.D. thesis, he is actively working to understand the influence of feedstock powder properties on the cold spray and tribology of Ti based metal matrix composites. In his free time, Vamsi likes, playing cricket, bowling and listing to music.

Bruno Noronha Castilho

DOCTORAL STUDENT

 

(2018 - present), Thermally sprayed coatings for high temperature seals in aeroengines.

Office: 2530, Wong Building

Bruno was born in Belo Horizonte, Brazil, where he attained his bachelor’s degree in Mechanical Engineering. Upon his graduation (2015), he moved to São Carlos for his master’s studies at the University of São Paulo, also in Mechanical Engineering. During his Master’s, Bruno developed and characterized multilayered coatings produced by magnetron sputtering (HiPIMS and dcMS) by optimizing deposition parameters with the main objective of reducing wear of piston rings applied in heavy-duty diesel engines. In September 2018, Bruno joined Prof. Chromik’s group as a PhD student. His current interests include thermally sprayed coatings for wear-resistant applications and the investigation of the wear behaviour of coatings in high temperature environment. In his spare time, Bruno enjoys playing games, reading and watching Formula 1.

 

Alejandra was born in Mexico City, she obtained her bachelor’s degree in Metallurgy and Materials Engineering in the National Polytechnic Institute (IPN), Mexico. In 2010, she joined a global manufacturer and supplier of steel pipes based in Veracruz, Mexico as part of the Global trainee program and then as a researcher in the Metallurgy and Materials Department. After 4 years, she decided to continue her master’s program in Metallurgic Engineering. Her experience is related to chemical, microstructural and mechanical characterization of HSLA steels for extreme environments. In 2019 she joined Professor Chromik's research group as a PhD student, her research involves understanding the wear mechanisms of thermally sprayed coatings for high-temperature applications.
