Abstract

An apparatus 1 for the plasma spraying of a substrate 2 comprises a reaction chamber 3 at one end of which is located a plasma torch. A plasma forming gas is delivered under pressure to the torch such that a plasma jet is produced which extends along the length of the reaction chamber 3. An inlet port 8 is provided in the torch for the passage therethrough of a powder material and inlet ports 4 are provided in the reaction chamber 3 for injecting a reactive gas such as methane into the plasma jet.
