Definitions
- This invention is directed at metallic alloys, and more particularly at unique metallic alloys having low electrical and thermal conductivity. In coating form, when applied, such alloys present the ability to provide thermal barrier characteristics to a selected substrate.
- Metals and metallic alloys have metallic bonds consisting of metal ion cores surrounded by a sea of electrons. These free electrons which arise from an unfilled outer energy band allow the metal to have high electrical and thermal conductivity which makes this class of materials conductors. Due to the nature of the metallic bonds, metals and metallic alloys may exhibit a characteristic range of properties such as electrical and thermal conductivity. Typical metallic materials may exhibit values of electrical resistivity that generally fall in a range of between about 1.5 to 145 10 ⁇ 8 ⁇ m, with iron having an electrical resistivity of about 8.6 10 ⁇ 8 ⁇ m. Typical values of thermal conductivity for metallic materials may be in a range of between about 0.2 to 4.3 watts/cm° C., with iron exhibiting a thermal conductivity of about 0.8 watts/cm° C.
- ceramics are a class of materials which typically contain positive ions and negative ions resulting from electron transfer from a cation atom to an anion atom. All of the electron density in ceramics is strongly bonded resulting in a filled outer energy band. Ceramic alloys, due to the nature of their ionic bonding, will exhibit a different characteristic range of properties such as electrical and thermal conductivity. Because of the lack of free electrons, ceramics generally have poor electrical and thermal conductivity and are considered insulators. Thus, ceramics may be suitable for use in applications such as thermal barrier coatings while metals are not.
- a metal alloy comprising an alloy metal and greater than about 4 atomic % of at least one P-group alloying element.
- a method of reducing the thermal and/or electrical conductivity of a metal alloy composition comprising supplying a base metal with a free electron density, supplying a P-group alloying element and combining said P-group alloying element with said base metal and decreasing the free electron density of the base metal.
- a metallic alloy which exhibits relatively low thermal conductivity and a low electrical conductivity.
- the alloy may include primary alloying metals, such as iron, nickel, cobalt, aluminum, copper, zinc, titanium, zirconium, niobium, molybdenum, tantalum, vanadium, hafnium, tungsten, manganese, and combinations thereof, and increased fractions of P-Group elemental additions in the alloy composition.
- P-group elements are the non-metal and semi-metal constituents of groups IIIA, IVA, VA, VIA, and VIIA found in the periodic table, including but not limited to phosphorous, carbon, boron, silicon, sulfur, and nitrogen.
- the metallic alloy exhibiting relatively low thermal conductivity and electrical conductivity may be provided as a coating suitable for thermal and/or electrical barrier applications on a variety of substrates.
- metallic alloys are provided that exhibit relatively low thermal and electrical conductivity.
- the alloys according to the present invention may include relatively high fractions of P-group elemental alloying additions in admixture with a metal.
- the added P-group elements may include, but are not limited to, carbon, nitrogen, phosphorus, silicon, sulfur and boron.
- the P-group elements may be alloyed with the metal according to such methods as by the addition of the P-group elements to the metal in a melt state.
- an alloy according to the present invention may include P-group alloying constituents. Such constituents are preferably present at a level of at least 4 at % (atomic percent) of the alloy. Desirably, the alloy consistent with the present invention may include more than one alloying component selected from P-group elements, such that the collective content of all of the P-group elements is between about 4 at % to 50 at %.
- the alloy may include relatively large fractions of silicon in the alloy composition.
- an iron/silicon coating alloy can be prepared according to the present invention which coating may be applied, e.g., to any given substrate.
- the metal alloy may be applied as coating using a thermal spray process.
- the resulting coating maybe employed to provide a thermal and/or electrical barrier coating.
- the coating provides thermal and/or electrical barrier properties exhibited similar to a ceramic material, however without the associated brittleness of conventional ceramic coatings.
- the alloy of the present invention may also be processed by any know means to process a liquid melt including conventional casting (permanent mold, die, injection, sand, continuous casting, etc.) or higher cooling rate, i.e. rapid solidification, processes including melt spinning, atomization (centrifugal, gas,. water, explosive), or splat quenching.
- a liquid melt including conventional casting (permanent mold, die, injection, sand, continuous casting, etc.) or higher cooling rate, i.e. rapid solidification, processes including melt spinning, atomization (centrifugal, gas,. water, explosive), or splat quenching.
- melt spinning centrifugal, gas,. water, explosive
- splat quenching atomization to produce powder in the target size range for various thermal spray coating application devices.
- the present invention provides a metal alloy that behaves similar to a ceramic with respect to electrical and thermal conductivity.
- An exemplary alloy consistent with the present invention was prepared containing a combination of several alloying elements present at a total level of 25.0 atomic % P-group alloying elements in combination with, e.g. iron.
- the experimental alloy was produced by combining multiple P group elements according to the following distribution: 16.0 atomic % boron, 4.0 atomic % carbon, and 5.0 atomic % silicon with 54.5 atomic % iron, 15.0 atomic % chromium, 2.0 atomic % manganese, 2.0 atomic % molybdenum, and 1.5 atomic % tungsten.
- the experimental alloy was prepared by mixing the alloying elements at the disclosed ratios and then melting the alloying ingredients using radio frequency induction in a ceramic crucible. The alloy was then process into a powder form by first aspirating molten alloy to initiate flow, and then supplying high pressure argon gas to the melt stream in a close coupled gas atomization nozzle. The power which was produced exhibited a Gaussian size distribution with a mean particle size of 30 microns. The atomized powder was further air classified to yield preferred powder sized either in the range of 10-45 microns or 22-53 microns. These preferred size feed stock powders were then sprayed onto selected metal substrates using high velocity oxy-fuel thermal spray systems to provide a coating on the selected substrates.
- conventional metals and metallic alloys typically cool rapidly from a melt state on a conventional water cooled copper arc-melter, and can be safely handled in a matter of a few minutes.
- the experimental alloy prepared as described above required in excess of 30 minutes to cool from a melt state down to a safe handling temperature after being melted on a water cooled copper hearth arc-melter.
- the experimental alloy powder does not transfer heat sufficiently using conventional operating parameters due to its relatively low conductivity and inability to absorb heat.
- conventional alloys can be sprayed with equivalence ratios (kerosene fuel/oxygen fuel flow rate) equal to 0.8. Because of the low thermal conductivity of the modified experimental alloys, much higher equivalence ratios, in the range of 0.9-1.2, are necessary in order to provide sufficient heating of the power.
- the very thin deposit (225 ⁇ m thick weld) took excessive time before another layer can be deposited since it glows red hot for an extended time.
- alloy compositions of the following are to be noted, with the numbers reflecting atomic %: SHS717 Powder, with an alloy composition of Fe (52.3), Cr (19.0), Mo (2.5), W (1.7), B (16.0), C (4.0), Si (2.5) and Mn (2.0); SHS717 wire, with an alloy composition of Fe (55.9), Cr (22.0), Mo (0.6), W (0.4), B (15.6), C (3.5), Si (1.2) and Mn (0.9).
- the thermal conductivity data for the SHS717 coatings was measured by a Laser Flash method and the results are given in Table 1. Note that the wire-arc conductivity is generally lower than the HVOF due to the higher porosity in the wire-arc coating. Note that the conductivity of the coatings is lower than that of titanium which is the lowest thermal conductivity metal and at room temperature are even lower than alumina ceramic (see Table 2).
