When I was writing my book "Metallic Coatings," I decided to also address non-metallic coatings on metals in the same way. This decision was further reinforced by several discussions about my book "Metallic Coatings," where there was a direct request for a work on "Non-Metallic Coatings" from my pen. I also received this demand from practical applications multiple times. Therefore, I hope that with this present work, I have fulfilled a request from the practical field. "Non-Metallic Coatings," just like metallic and organic coatings, represent a very effective means of increasing the durability of our metallic materials, which have already secured a strong position in surface technology. With many non-metallic coatings.
