Definitions

  • the present invention relates generally to the utilization of a thermal spray technique for application of polymeric materials, and particularly to a method that facilitates application of polyetheretherketone (PEEK) composite to a substrate.
  • PEEK polyetheretherketone
  • Thermal spray techniques have been used for coating target materials or substrates with a desired material or composition of materials.
  • thermal spray technology refers to a family of coating techniques based on the use of a high temperature heat source used to melt a material and propel it at a substrate, thereby forming a coating on the substrate.
  • Powder, rod or wire can be used as raw materials that are melted by, for example, electric arcs, combustible gases or a combination of both.
  • the heat melts the coating material which is then accelerated by a compressed gas towards the substrate to be coated. As the coating material melts, it forms platelets that are propelled towards the substrate where they adhere to the substrate and to each other. The platelets build up and cool into a lamellar structure forming the coating.
  • HVOF high velocity oxy fuel
  • PEEK for example, has many applications as a coating material, but the utilization of an HVOF process in applying a coating of PEEK material to a substrate has proved difficult. PEEK can degrade in the presence of extreme heat or a high temperature flame. However, if the PEEK powder is not heated sufficiently, unmelted particles are propelled against the desired substrate resulting in poor adhesion and undesirably high porosity.
  • PEEK polymeric materials having good thermal stability at high temperature
  • the utilization of polymeric materials having good thermal stability at high temperature, such as PEEK can be accomplished by molding the PEEK material onto a desired substrate.
  • the application of PEEK coating through molding is limited with respect to the types of components that can be coated. Additionally, the molding technique tends to be more costly, particularly when the molded coating and/or coated component requires additional machining prior to use of the component.
  • the application of materials such as PEEK through an HVOF process would alleviate these problems.
  • the present invention features a method for applying a PEEK composite material to a metallic substrate.
  • the method includes the step of applying a metallic bond layer on the metallic substrate. Further, the method includes depositing a layer of PEEK composite material over the metallic bond layer by an HVOF process.
  • a method for applying a polymeric material to a substrate to create a high load thrust bearing surface.
  • the method includes preparing a metal substrate, and applying a metallic bond layer to the metal substrate. Additionally, a polymeric material, having a melting temperature above 300°C is deposited over the metallic bond layer by spraying heated particles of the polymeric material towards the metal substrate.
  • a method for applying a PEEK composite material to a component surface.
  • the method includes preparing a surface of a component to receive a PEEK composite mixture.
  • the PEEK composite mixture is sprayed via an HVOF process over the surface to form a PEEK composite layer.
  • the PEEK composite layer is then annealed to create a durable coating.
  • the present invention relates to the utilization of a thermal spray technique to apply a polymer material, having good thermal stability at high temperature, to a substrate.
  • the method disclosed according to a preferred embodiment of the present invention is particularly useful in the application of a polyetheretherketone (PEEK) composite by a high velocity oxy fuel (HVOF) process to a metal substrate.
  • PEEK polyetheretherketone
  • HVOF high velocity oxy fuel
  • the process provides a durable PEEK composite coating having a low porosity, typically less than 1% porosity. This type of coating is amenable to use on components that act as bearing components.
  • the following describes an exemplary application of this process in creating bearing surfaces by applying the PEEK composite coating to pads used in thrust bearings.
  • thrust bearings are used in a variety of applications, including applications in various submergible components found in submergible pumping systems.
  • Submergible pumping system components are used in relatively harsh wellbore environments under substantial load in pumping production fluids to the earth's surface.
  • inventive process is not limited to this particularly amenable application.
  • a coated, thrust bearing pad 10 includes a metal substrate 12.
  • Metal substrate 12 typically is made from a steel plate.
  • a first bond layer 14, comprising copper, for example, is electroplated to metal substrate 12.
  • a second bond layer 16, comprising bronze, for example, is applied to the first bond layer 14 and metal substrate 12 by a sintering process. This process creates a relatively porous bronze layer having voids into which molten PEEK material may flow.
  • a layer of PEEK composite material 18 may be deposited by melting and pressing PEEK composite material onto the bronze second bond layer 16.
  • the coated steel plate is machined into coatcd thrust bearing pad 10.
  • the present invention provides a more efficient, less cost intensive approach for coating a substrate with a durable polymeric material, such as a PEEK composite material.
  • a durable polymeric material such as a PEEK composite material.
  • the present method may be readily understood with reference to the block diagram of Figure 3.
  • a substrate layer must be prepared for receipt of a polymer layer via a thermal spray process.
  • the substrate is a metallic material, preferably stainless steel but other metallic materials may be appropriate depending on the specific application.
  • the first step in the process is preparation of the substrate material as illustrated by block 20 of Figure 3.
  • the substrate preferably is cleaned by removing dirt, moisture, oil and other contaminants from the surface to be coated. To facilitate adherence, it is also desirable to roughen the surface to be coated. If the substrate is stainless steel, it is preferred that the surface be roughened by grit blasting the substrate with aluminum oxide having a grit mesh size 28.
  • the polymeric material is prepared for use in coating the substrate, as illustrated in block 22 of Figure 3.
  • the polymeric material have a high melting temperature, i.e., above 300°C.
  • a PEEK material is used to prepare a composite material in powdered form.
  • a preferred composite comprises a mixture of PEEK with polytetrafluoroethylene (PTFE) and carbon. These materials enhance the low coefficient of friction and excellent wear properties of PEEK.
  • An exemplary ratio of materials is approximately 70% PEEK mixed with approximately 20% PTFE and approximately 10% carbon. Additionally, the selection of appropriate particle size can be critical to the HVOF process. It has been determined that optimal particle sizes for the various components of the PEEK composite are approximately 70 microns for the PEEK; approximately 53 microns for the PTFE; and approximately 6 microns for the carbon particles. Although specific mixture percentages and particle sizes have been provided, other mixture ratios, particle sizes, and mixture components may be amenable to the process of the present invention.
  • a bonding layer may be applied to the substrate, as illustrated in block 24 of Figure 3.
  • the bonding layer preferably is a metallic material having sufficient surface asperities to facilitate the mechanical bonding of the PEEK composite layer to the substrate.
  • a single layer of metallic material such as nickel aluminum alloy, is applied. This material has desired characteristics at high temperature and provides excellent bonding to a stainless steel substrate. Other bonding layer materials may work better with substrates formed of materials other than stainless steel.
  • the nickel aluminum alloy is arc sprayed against the substrate.
  • Arc spraying uses a high energy electric arc generated by bringing two electrically energized wires into contact with each other. The arc energy melts the wires, and compressed air atomizes the molten material and propels it onto the substrate, leaving a bonding layer.
  • the bond layer has good thermal conductivity to help dissipate heat from the PEEK layer, particularly when the PEEK material is used as a bearing surface. It has been determined that an optimal thickness for the bond coat is in the range of approximately 0.014 to 0.018 inches.
  • the PEEK composite material is applied to the substrate over the bonding layer by a thermal spray, as illustrated by block 26 of Figure 3.
  • a thermal spray as illustrated by block 26 of Figure 3.
  • an HVOF process is utilized to apply the PEEK composite mixture to the substrate and the bonding layer.
  • An optimum window of spray parameters has been established to ensure low porosity and great bond strength to permit the PEEK composite layer to be used in load bearing environments.
  • the HVOF process is carried out with the aid of a thermal spray gun, such as the Miller Thermal Spray Gun, Model HV2000, available from Miller Thermal, Inc.
  • the Miller Thermal Spray Gun is equipped with an axial powder feed configuration and is controlled by the Miller Thermal Computerized Console, Model 4600.
  • the Miller Thermal Spray Gun is equipped with a 12mm combustion chamber and the fuel gas, preferably hydrogen, to oxygen ratio is 3.33.
  • a carrier gas preferably nitrogen, is flowed through the thermal spray gun at a flow rate of 30scfh to feed powder into the combustion chamber.
  • the powderized PEEK composite mixture is fed to the thermal spray gun via an electronically controlled, pressurized hopper unit, as is well known to those of ordinary skill in the art.
  • the PEEK composite material is then injected through the flame of the HVOF thermal spray gun and heated to at least the melting point of the PEEK composite material, e.g. approximately 340°C.
  • the powder particles of the PEEK composite are partially or fully melted and propelled towards the substrate and bonding layer. This creates a stream of semi-molten or molten particles or platelets that hit the substrate to form a continuous coating typically having a lamellar structure.
  • a mechanical interlocking process takes place between the particles and the rough substrate/bonding layer to securely bond the continuous coating to the substrate.
  • the PEEK composite powder is fed at a rate of 11 grams per minute and the thermal spray gun is moved at a traverse speed of 754 millimeters per second with a standoff of 7 inches.
  • the standoff refers to the distance between the substrate and the outlet tip of the thermal spray gun.
  • the PEEK composite coating is built up in multiple passes to a thickness between approximately 0.019 inches and 0.021 inches. Typically, there is one preheat cycle and 30 passes, following which, the coating is allowed to cool by a natural slow cool.
  • the post-deposition annealing process provides a more durable coating. It facilitates the removal of thermal history and residual stresses. It also increases the level of crystallinity of the PEEK composite coating.
  • a preferred post-deposition annealing process comprises heating the PEEK composite layer to approximately 400°C and holding it at that temperature for approximately 30 minutes.
  • the PEEK composite layer, along with the substrate and bonding layer, then undergoes a controlled cooling to approximately 270°C at which temperature it is held for approximately 10 minutes. Thereafter, the PEEK composite layer, substrate and bonding layer undergo a controlled cooling to below 60°C.
  • the above-described method provides a PEEK composite coating that is easily applied and has low porosity, typically on the order of less than one percent porosity.
  • the PEEK composite layer is particularly amenable to use as a bearing surface because of its low coefficient of friction, excellent wear properties and low porosity achieved with this process.
  • thrust pad 30 for use as thrust bearings, such as those described above with reference to Figures 1 and 2.
  • a thrust pad 30 produced according to the method of the present invention is illustrated in Figures 4 and 5.
  • thrust pad 30 includes a substrate 32 that is formed as an investment casting of PH17-4 stainless steel. Substrate 32 initially is prepared as described above with reference to block 20 of Figure 3.
  • a single bonding layer 34 comprising a nickel aluminum alloy, is applied to substrate 32 by arc spraying, as described above with reference to block 24 of Figure 3.
  • a PEEK composite material is prepared and sprayed against substrate 32 and bond layer 34 as described above with reference to blocks 22 and 26 of Figure 3.
  • a multiplicity of molten or partially molten platelets 36 bond to substrate 32, bonding layer 34 and each other to form a PEEK composite layer 38.
  • the thrust pad 30, including PEEK composite layer 38 preferably is subjected to the post-deposition annealing described above with reference to block 28 of Figure 3.
  • the formation of thrust pad 30 is efficient and inexpensive relative to the molding process of the prior art. It also provides a durable, PEEK composite bearing surface readily used in hostile environments, such as those encountered in a downhole, wellbore environment.
  • the foregoing description is of a preferred exemplary embodiment of this invention, and that the invention is not limited to the specific form shown.
  • the method may be applied to a wide variety of components; the precise mixture of constituents in the PEEK composite may be adjusted for desired applications or effects; the HVOF parameters may be adjusted according to the PEEK composite mixture, the particulate size, the type of HVOF thermal spray gun utilized and the environment in which the process is implemented; and the bonding layer material may be adjusted according the various other parameters, including the material used in formation of the substrate.
