subcontract flame deposit coatings

  • The so-called remote combustion chemical vapour deposition is a new variant of the classical CCVD process. It likewise uses flames to deposit thin films, however, this method is based on other chemical reaction mechanisms and offers further abilities for deposition of layer systems which are not practicable by means of CCVD, e.g. titanium dioxide.

  • What is Thermal Spray ? Graphic courtesy of Westaim Ambeon thermal spraying, a group of coating processes in which finely divided metallic or nonmetallic materials are deposited in a molten or semimolten condition to form a coating. The coating material may be in the form of powder, ceramic-rod, wire, or molten materials. (1)

  • Plasma transferred wire arc (PTWA) thermal spraying is a thermal spraying process that deposits a coating on the internal surface of a cylindrical surface, or external surface of any geometry. It is predominantly known for its use in coating the cylinder bores of an engine, enabling the use of aluminum engine blocks without the need for heavy cast iron sleeves.
