Ceramic Coatings for metal machine parts

The ceramic coating for pipelines and other specialized metal parts developed by Dr. Florin Esanu and others at the Alberta Research Council uses a combination of ceramic solutions applied at high temperatures to a specific surface.

The patent application for the coating process utilizes ceramic particles applied as part of a complex matrix with other materials: "The coating comprises a ceramic matrix formed by a high temperature interaction between fine vitreous particles and the solid content of a ceramic liquid precursor, such as the solid component of a ceramic sol; and a filler comprising one or more materials selected from the group of ceramic, glass, and metal particles, the filler being integrated in the matrix."

The application also specifies that the filler material may contain ceramic particles of "alumina, silica…" and other chemicals, as well as other particles "from the group of metallic particles consisting of aluminum, stainless steel, and nickel alloys."

The coating can be either sprayed on to a target surface, or dip coated by immersing a product into the coating solution. Further heating of the coating solution after initial application creates an initial ceramic layer, which can be enhanced by applying another ceramic sol (a solution with microscopic ceramic particles uniformly distributed) that covers the first coating. A second heating then creates a ceramic matrix with integrated filler particles.

International Polymers Canada (IPC), an Edmonton-based coatings specialist company, was granted the commercial production and marketing license for Esanu’s process.
