In the method for the coating of a substrate (3) a hybrid coating method is carried out with a thermal process jet (2) which makes it possible to combine the properties of a thermal spray method with those of a reactive vapour phase deposition. The properties of the process jet are determined by controllable process parameters in particular by the parameters of pressure enthalpy, composition of a process gas mixture (G) and composition and form of application of a coating material (M). The coating material is partly or completely evaporated in dependence on the controllable parameters. The phases of the coating material present in vapour form (23b) and optionally, in condensed, i.e. solid …

Why it's free to use
- Filed March 8, 2004 and granted February 14, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 8, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 8, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
