Definitions

  • the present invention relates to thermal spray material and its coated articles excellent in high-temperature wear resistance and build-up resistance which are mainly used for carrier rolls for high-temperature heat-treating materials in a continuous heat-treating furnace.
  • a steel plate for example, is continuously annealed, the plate is passed through an oxidizing or reducing atmosphere at a temperature of 600 to 1300°C, and many heat-resistant rolls are located and used as hearth rolls to support this steel plate.
  • the continuous use of the rolls for many hours often causes adhered oxide scale on the steel plate or ferrous powder to adhere and deposit on the surface of each of the rolls into so-called build-up. Since the surface of the steel plate to be carried is deteriorated such as occurrence of scratches when this build-up occurs, the annealing operation sometimes may have to be immediately suspended to repair such as grinding the roll surface or replacement the roll.
  • preventive measures against build-up on the roll surface are proposed, such as, for example, being disclosed in JP-A-58-249839, JP-A-59-70712, JP-A-59-126772 and JP-A-63-199857.
  • preventive measures against build-up on the hearth roll surface it is suggested in the above-mentioned Japanese Patent Unexamined Publications to coat the roll surface by means of the thermal spraying method for use with the metallic oxide such as Al2O3, SiO2, ZrO2 and Cr2O3, with the carbide, for example, Cr3C2 or with one or more of these compounds (or ceramic materials) blended with metal such as Co, Cr, Ni, Al, Y, Mo, Zr or an alloy thereof.
  • the present invention intends to solve these problems by using thermal sprayed layer of powder containing oxidation-resistant alloy particles and metal boride particles.
  • a part of the oxidation-resistant alloy powder and a part of metal boride powder may be replaced with oxide particles to disperse metallic oxide particles all over the thermal sprayed layer, or the dispersion of oxidation-resistant alloy may be strengthened by uniformly dispersing a very small amount of fine metallic oxide particles in the oxidation-resistant alloy powder, or precipitation hardening of oxidation-resistant alloy may be performed by additioning titanium and carbon and precipitating these as titanium carbide in the oxidation-resistant alloy.
  • Equipment members such as a hearth roll or other carrier members used in a furnace, have been coated with a cermet containing 5 to 95 vol.% of the compounds of oxide (or ceramic material), etc. on the surface of base material of heat resisting cast steel, etc. by the spraying method so far.
  • the present invention solves this problem by using metal boride which has a thermal coefficient of expansion about equal to that of metallic material and is excellent in preventing build-up.
  • the build-up occurs when oxide or ferrous powder formed on a steel plate adheres and deposits on the surface of the hearth roll, and the inventors have found out that metal boride is very excellent in preventing build-up. Also it is well known that the thermal coefficient of expansion of metal boride is about equal to that of metallic material.
  • any of the following may be used: chrome boride, zirconium boride, titanium boride, molybdenum boride, niobium boride, tantalum boride, tungsten boride and hafnium boride.
  • the atmosphere in a continuous refining annealing line, in which hearth rolls and other carrier members are used is under oxidizing free atmosphere mainly containing nitrogen and hydrogen, but the above-mentioned carrier members are often exposed to oxidizing atmosphere during temperature of the furnace are rising or lowering when the operation suspends for repair, etc. Accordingly since especially chrome-, zirconium- and titanium-boride are excellent in oxidation resistance, respectively, among the above metal borides, these are suitable for the surface coating material for hearth rolls and so on.
  • the surface coating layer for steel manufacturing process equipment members such as hearth rolls is damaged by the wear besides the heat shock mentioned above.
  • the metal boride used for the present invention is also excellent in wear resistance because it has a very high hardness. Since, however, it is deficient in toughness owing to high hardness, there are problems with relation to shock resistance and adhesive strength in case of a load being rapidly applied to the coating. Therefore the sprayed coating layer used for the present invention should be a cermet composed of metal boride and alloy.
  • the content of the metal boride is limited to 5 to 50 vol.%; the cermet is inferior in wear resistance and a property of preventing build-up in case of less than 5 vol.% of the metal boride, and is inferior in shock resistance, adhesive strength and heat-shock resistance over in case of more than 50 vol.% of the metal boride.
  • Ten to 20 vol.% of the metal boride is most desirable.
  • Such cermet coating layer is generally obtained by spraying blended powder consisting of each ingredient powders. But composite powder constituted by the monolithic combination of individual particles or each of ingredients is desirable from a standpoint of uniformity of a coating layer.
  • the composite powder of the present invention can be prepared by a so-called mechanical alloying method, in which metal powders of the respective components are blended and stirred by the use of a stirring machine at a high speed with a high energy for a certain period of time, whereby a composite powder alloyed mechanically containing the respective component particles as mechanically bonded therein can be obtained.
  • each of particles of the composite powder is a composite particle alloyed mechanically and consists of every components.
  • the mechanical alloying method is a high-energy milling techniques as described in U.S. Patent Nos. 3,591,362 and 2,740,210.
  • the steel manufacturing process roll used at high temperature such as hearth rolls, may be exposed to some oxidizing atmosphere. Therefore the oxidation resistance is always required and important.
  • the oxidation resistance is given through alloy portions, and the amount of the alloy portions in cermet used for the present invention should be equal to or more than the content of metal boride. Further, it is naturally required for the alloy portions to have a property of preventing build-up.
  • To provide metallic material with oxidation resistance it becomes necessary to form a thin, close oxide protection coating for prevention of oxygen diffusion on the surface.
  • chromium oxide or aluminum oxide is excellent, and chromium and aluminum should be always contained in the alloy of iron, nickel or cobalt.
  • Chromium forms a protective coating of chromium oxide below 800°C, and this chromium effect is not sufficient when its chromium content in the alloy is 5 wt.% or less. When cromium content in the alloy is more than 40 wt.%, the alloy portions as a whole become brittle. More desirably, Cr content in the alloy is 17 to 27 wt.%.
  • Aluminum accelerates forming of a protective coating of aluminum oxide at 800°C or more, and forming of a protective coating of chromium oxide at 800°C or less.
  • aluminum content in the alloy is 5 wt.% or less, this aluminum effect is not sufficient, but when the content exceeds 20 wt.%, the alloy portions becomes remarkably brittle like in case of chromium. More desirably, aluminum content in the alloy is 5 to 15 wt.%. When the entire alloy layer becomes brittle, the heat-shock resistance and adhesion strength of the sprayed coating layer becomes remarkably brittle. A protective coating of chromium oxide or aluminum oxide is excellent in preventing build-up.
  • any one excellent in oxidation resistance thus will do, and therefore rare-earth metal such as yttrium or silicon, etc. may be contained in the alloy besides the above-mentioned chromium and aluminum to improve the oxidation resistance.
  • the content of rare-earth metal or silicon should be less than 2 wt.% in the alloy.
  • the desirable oxidation resistant alloy in this invention contains essentially of about from 15 to 40 wt.% of Cr, from 5 to 20 wt.% of Al and the balance of Ni or Co.
  • the alloy consists essentially of about from 17 to 27 wt.% of Cr, from 5 to 15 wt.% of Al, less than 2 wt.% of Si, less than 2 wt.% of Y, less than 2 wt.% of Y2O3 and the balance of Ni or Co.
  • the alloy powder is generally produced from a molten alloy of a specified composition by an inert gas atomizing method and so on, and it may be produced by alloying each metal components powder by a mechanical alloying process.
  • the material of the present invention is mainly composed of cermet of oxidation-resistant alloy containing metal boride.
  • the following hard oxide particles can be contained: aluminum oxide, chromium oxide, titanium oxide, silicon dioxide, zirconium oxide, magnesium oxide, yttrium oxide, a rare-earth oxide, etc.
  • a part of oxidation-resistant alloy particles and a part of metal boride particles may be replaced with the above-mentioned oxide powder to disperse oxide particles all over the sprayed coating layer. Its content is limited to 50 vol.% or less of the cermet components consisting of oxidation-resistant alloy particles and metal boride particles not to deteriorate the heat-shock resistance and adhesive strength.
  • the oxidation-resistant alloy may be hardened by using a method not to deteriorate the toughness. This can be performed by uniformly dispersing a very small amount of fine oxide particles of aluminum oxide, chromium oxide, titanium dioxide, silicon dioxide, zirconium oxide, magnesium oxide, yttrium oxide, a rare-earth oxide or the like in the oxidation-resistant alloy to strengthen the alloy matrix.
  • the content of the fine oxide particles in the oxidation-resistant alloy is limited to 2 vol.% or less, and when this value is exceeded, the oxidation-resistant alloy becomes brittle, resulting in deteriorated heat-shock resistance and adhesive strength of the sprayed coating layer.
  • titanium carbide is excellent in this effect. That is, to precipitate titanium carbide, it is possible to harden the oxidation-resistant alloy without deteriorating oxidation resistance and build-up preventing effect of the oxidation-resistant alloy. To harden the alloy, it is effective to contain 10 wt.% or less of titanium and 5 wt.% or less of carbon in the alloy. Addition of more than these values allows the alloy to becomes brittle, and deteriorates the heat-shock resistance and adhesive strength of the sprayed coating layer.
  • thermal spray material composition of the present invention is used by coating the base material surface of equipment members such as hearth rolls by using a detonation spraying method, a supersonic flame spraying method, or general spraying techniques such as a plasma spraying method. Since, however, thermal spray material composition of the present invention contains heat decomposable substance such as metal boride, the coat formed by using the detonation spraying method or supersonic flame spraying method is excellent in various characteristics, and especially the coat formed by the detonation spraying method is most desirable.
