EVENT DETAILS

Cold spray is a metal powder consolidation process that can be used to prepare 2D coatings or 3D structural parts. During cold spray, metal particles are accelerated to high velocities using a high-pressure gas stream; the particles then “cold weld” onto the substrate material upon impact. Cold spray has generally no restrictions in terms of the shape and size of the final part, and exhibits a very high build rate, overcoming the slow production rates in AM methods based on metal melting, hence it is an ideal process for rapid manufacturing of large structural parts. Unlike AM processes based on the melting of metal powders, cold spray is a solid-state process that can avoid issues related to melting and solidification (e.g., solidification cracks) and damages due to heat (e.g., oxidation and changes in composition). In this talk, the fundamentals of cold spray will be quickly overviewed, followed by the introduction of three novel applications of cold spray, namely, Metallization of polymer and polymer composites, Development of antiviral coatings by cold spray, and Surface strengthening of metals by cold spray shot peening.

Biography
Prof. Hanqing Che is a full professor at Chongqing University. He obtained his Bachelor’s degree from Xi’an Jiaotong University, and his Master’s and PhD degrees from the University of British Columbia and McGill University, respectively.
Prof. Che has more than ten years of research experience in cold spray and advanced processing of aerospace materials. Since 2013, he has participated in 9 aerospace research projects funded by the Canadian government on cold spray or including cold spray as the primary technique. With those research projects, he has collaborated closely with national institutions such as the National Research Council of Canada (NRC) and the CanmetMATERIALS National Laboratory, and has also cooperated with the world’s leading aircraft and aero-engine manufacturers, such as General Electric, Bombardier Aerospace, and Bell Helicopter, to complete a series of research projects that focused on key issues in the production and strategic development of those enterprises.

Prof. Che has published more than 40 academic papers on related fundamental research, including 6 invited papers, 2 of which have been selected as the JTST Editor’s Choice articles; he has won the Young Professional Award at the ASM North American Cold Spray Conference, along with many other awards at major international academic conferences. He currently serves as a member of both the Program Committee and the Training Committee of the ASM Thermal Spray Society.
