    Dear Thermal Spray Community!

    This is a friendly reminder from ASM Thermal Spray Society (TSS).

    The ASM-TSS Open Mic series provides students and emerging professionals with a rare opportunity to interact with the most influential leaders in the global thermal spray community.

    One month from today, on March 15 (2023), the next TSS Open Mic speaker will be Dr. Jegan (Karthi) Karthikeyan (FASM), Retired Director of R&D, Hannecard/ASB Industries (USA) - Consultant on Thermal Spray Technology.

    The title of his talk will be: "Unresolved Challenges: A Journey in Thermal Spray Technology".

    Abstract: Last half a century, I have been involved in research and development in almost all aspects of Thermal Spray Technology. Studies include fields such as design and development of spray guns, process characterization, engineered coatings, conceptualization and development of novel spray techniques, coating characterization, intricacies of cold spray technique and coating, etc. During this journey, some of these studies have been abandoned due to various 'worldly' reasons. A typical example is the measurement of coating thickness. Of all the coating properties, thickness is the most basic and absolutely required data. When the substrate-coating pair has materials with large difference in either electrical or magnetic properties, one can use Eddy or Magnetic probes to quickly and reliably(?) record the thickness. But, when this is not the case, (such as WC-Co coating on any non-ferrous substrate), this technique fails. In fact, the Cobalt content in the WC-Co coating makes this measurement near to impossible even on ferrous substrates. From the time Max Schoop developed the first spray gun in 1910 till today, a single reliable and universal thickness probe has not been developed. This is one of the unresolved challenges in (my) journey in thermal spray. This talk will cover a few of these unresolved challenges and attempt to indicate possible avenues to resolve them. For instance, can we exploit the explosive growth of technologies such as nuclear, laser, etc. and resolve this issue of coating thickness will be discussed. Hopefully, the present-day students and scientists will have the opportunity, interest and time to take up and resolve these challenges.

    For sure this presentation will be very important to students, post-docs and junior researchers who are building their scientific careers.

    Join us on Wednesday (March 15, 2023) at 9:00 h (North American ET).

    And thanks to our sponsors, the TSS Open Mic is totally free.

    To register to attend this presentation, and/or the incoming ones, and/or watch the previous ones is very easy. Just click here: Home - TSS Open Mic Series (asminternational.org)
