The application of thermally sprayed ceramic or metallic coatings has become an important part of surface
coating technology. Over the last two decades, the industry has seen extensive development of sophisticated equipment
that has simplified the application of thermal spray coating to complex surfaces. The availability of a broad range of
tailored feedstock materials, and sensitive characterization and quality assurance methods has made surface coatings and
their improved deposition techniques increasingly attractive. The drive for new and improved materials and
characterization methods has forced engineers and designers to modify old techniques and invented new ones to satisfy
the growing demand for thermal spray materials. These materials are used for wear and corrosion protection of engineered
components and structures. This review will cover significant patented progress in the field of wear- and corrosionresistant
thermal spray coatings achieved during the past five years.
Keywords: Corrosion resistant coating, thermal spray coatings, wear resistant coating.
