Cu-Al alloy and Mo coatings were deposited on a low carbon steel substrate using an atmospheric plasma spray machine. Pure PTFE and PTFE metal powder composites were deposited on the metallic coatings. Studied and compared are PTFE-metal coatings and PTFE compositesmetal coatings filled with different metal powders with the proportion of 10% (mass). Mass loss and coefficient of friction were measured under dry reciprocating sliding tests. The worn surfaces of samples were observed by microscopy. The influence of additives on the wear resistance was assessed.

“…Highly ordered aluminum oxide, calcium phosphate and titanium oxide crystals as well as titanyl phthalocyanine, tris(8-hydroxyquinoline) aluminum(III), tetracene and pentacene thin films were deposited onto PTFE patterned surfaces envisaging various applications. [21][22][23][24][25][26] We show in this work that thermal annealing induces morphological transitions of a highly amorphous PTFE surface structure into nanosized fibril textures. The structure of PTFE surface and the way that this structure was altered by thermal treatment were analyzed by AFM.…”

Plastic deformation has proved to be an attractive tool for obtaining ultrafine grained and nanocrystalline metallic materials. A description of plastic deformation as a technique to create nanotexturized polytetrafluoroethylene substrates free of defects, such as pores or impurities, which has potential applications as templates for the oriented growth of organic and inorganic compounds, is presented here. The obtained morphology characterized by nanosized fibrils arrangements was revealed by atomic force microscopy. Nanofibrils with a width from 330 to 980 nm and lengths from 1.85 to 11 microm were observed on polytetrafluoroethylene substrates annealed at 330 degrees C and 390 degrees C, respectively. Wide angle X-ray scattering spectra for untreated and annealed samples show that there is a slight decrease in the amorphous component for samples annealed at 380 degrees C but not for samples annealed at 330 degrees C showing that the amorphous substrate matrix in little altered by the annealing. The pattern formation is associated with superficial polymeric domains that become large crystalline nanofibrils in an amorphous matrix.

“…Its properties are well suited for mechanical, electrical and chemical components and cable insulation [1] and it is used for molded parts, electrical insulation or extrusions. However, due to high chemical inactivity and poor adhesion to other materials, there are only a few reports on coated PTFE [2,3].…”
