    Dear Thermal Spray Community,

    Would there be people in this group who know which thermal spray coating compositions are approved by the U.S. FDA as being "food grade acceptable"?

    Cheers!

    Hello Rogerio,

    Try contacting Satish Dixit at Plasma Technology Inc. (PTI) in Torrance, CA. Years back, I knew PTI had several coatings with FDA approval.

    Hi Rogerio,

    Thank you for this great question. Thermal-sprayed chromium oxide (Cr2O3) and chromium carbide (Cr3C2) coatings have been mentioned on the websites below as FDA-compliant coating solutions for food processing applications. According to the information provided on these websites, thermal spray coatings can provide high resistance against corrosion for parts exposed to acidic solutions and foodstuff residues. Please take a look at the following websites for additional information.

    Hi Milad, Rogerio 

    Based on my perspective and considering safety Cr2O3 is considered as a carcinogenic material. All that powder which content with Chromium are considered carcinogenic powder in thermal spray.

    it's become hexavalent chrome after oxidation which is not good for direct food contact applications. 


    Kind Regards

    Dear Rogerio 

    It's my pleasure to be part of this group. 

    let me know if any volunteers opportunities their for me in ASM TSS group. 


    I'll be more than happy to explore it. 

    Thanks and Regards

    Dear Chirag,

    It is an honour to have you and dozens of thermal sprayers within this group. It is a great opportunity to all of us to ask technical questions and share technical information related to thermal spraying. 

    Just like you... there are many thermal spray experts in here.

    And regarding your willingness to serve as volunteer to TSS... you are very welcome... it is noted... and I got your email.

    Cheers!

    Yes this is very good platform to discuss technical and new developments things for all thermal spray learner, beginner and experts. 

    Thank you so much Rogerio. I'm looking forward to it. 

    May be we can meet soon in US. I'm planning to attend Thermal Spray & Surface Engineering Forum & Expo in September.

    Fantastic Chirag,

    FYI - @ the TSSE 2022 we (thermal sprayers) will have a dedicated TSS networking area within the exposition, where we will have the (i) coffee-breaks, (ii) lunches, (iii) table tops and (iv) a poster competition for Emerging Professionals (graduate students and post-docs). Everything related to thermal spraying. Therefore... the networking will likely be intense :)

    The agenda of the TSSE 2022 can be found here: e1da5939-6033-8140-7125-8d0a715f0b95 (asminternational.org)

    The registration for the TSSE 2022 is now open: Registration - TSS Forum (asminternational.org)

    If I do not have any professional commitment at the NRC in that week, for sure I will be Thermal Spray & Surface Engineering Forum & Expo 2022 (TSSE 2022).

    And it will be a pleasure to meet you (and everybody else) F2F @ the TSSE 2022.

    ​Cheers!​
