Abstract
A high temperature thermal sprayable material, such as a metal or metal oxide, is adhered to the surface of a thermal sprayable plastic particle to form a cladding layer thereon. The high temperature material cladding layer provides a thermal barrier that allows use of the plastic in a high temperature thermal spray process to create a duplex coating containing plastic.
Claims11
A particle for depositing a coating on a substrate surface by a thermal spray process, the particle comprising:
- a plastic core;
- and
- a particulate cladding material, selected from the group consisting of ceramics and metals having a higher melting point than the plastic core, wherein the particulate cladding material is adhered to the plastic core and wherein the particulate cladding material forms a substantially continuous, thermally protective cladding layer around the plastic core to reduce premature melting and vaporization of the plastic core.
A particle for depositing a coating on a substrate surface by a thermal spray process, the particle comprising:
- a plastic core;
- a first particulate cladding material, selected from the group consisting of ceramics and metals having a higher melting point than the plastic core, wherein the first particulate cladding material is adhered to the plastic core and wherein the first particulate cladding materials forms a substantially continuous, thermally protective intermediate cladding layer to reduce premature melting and vaporization of the plastic core;
- and
- a second particulate cladding material, selected from the group consisting of ceramics and metals having a higher melting point than the plastic core, wherein the second particulate cladding material is bonded to the first particulate cladding material with an organic binder to form an outer cladding layer.
