Disclosed herein are systems and methods of using a coating solution such as an aromatic copolyester thermoset (ACT) to improve the wear, galling, and corrosion resistances of downhole tools and their sub-components. Aromatic copolyester thermoset may be reinforced with filler material. Further, the aromatic copolyester thermoset reinforced with filler material may be used in a borehole as a composite hollow profile, for example. In some examples, the systems may comprise a substrate for downhole applications coated with an aromatic thermosetting copolyester mixed with polytetrafluoroethylene (PTFE).
A system comprising a substrate for downhole applications coated with an aromatic thermosetting copolyester mixed with polytetrafluoroethylene (PTFE).
A system comprising a substrate for downhole applications coated with an aromatic thermosetting copolyester mixed with from about 0.1 wt % to about 10 wt % polytetrafluoroethylene (PTFE), wherein the substrate for downhole applications comprises at least one substrate selected from the group consisting of sub surface safety valves, barrier valves, mandrels, flow tubes, sleeves, threads, splined cylinders, drill bits, components of sand control screen assembly, seal assemblies, and any combination thereof.
A system comprising a substrate for downhole applications coated with an aromatic thermosetting copolyester mixed with from about 0.1 wt % to about 10 wt % polytetrafluoroethylene (PTFE), wherein the substrate is a metallic substrate selected from the group of metallic substrates consisting of high-strength low-alloy steels, martensitic stainless steels, supermartensitic stainless steels, duplex stainless steels, super duplex stainless steels, austenitic stainless steels, alloys in the nickel-chromium-molybdenum (Ni—Cr—Mo) family, solution-strengthened nickel-based alloys, precipitation-hardening nickel-based alloys, magnesium-based alloys, and any combination thereof.
