COMPOSITE POWDERS COMPRISING POLYMERS AND INORGANIC PARTICLES FOR THERMAL SPRAYED COATINGS

摘要

A particle for depositing a coating on a substrate surface by a low temperature thermal spray process having a plastic core and a particulate forming an non- continuous cladding layer around the plastic core so that enough heat can be transferred to the plastic core to cause it to melt but not so much so as to vaporize the plastic core. At the same time the particulate cladding material having a higher melting point does not melt. A particle having an inorganic core clad to a plastic outer layer is also provided. A process for making the clad material and for thermally spraying the clad material is provided. An article coated with the clad material is also provided.
