Definitions

  • Japanese Laid-Open Patent Publication No. 2003-129212 discloses a technique for forming a thermal spray coating from a thermal spraying powder having 90% particle size D 90 of 20 ⁇ m or less.
  • the thermal spraying powder of the above publication since the ratio of particles having a particle size of 1 ⁇ m or less in the thermal spraying powder is not specified, the thermal spraying powder could include a large amount of particles having a particle size of 1 ⁇ m or less. If the thermal spraying powder includes many particles having a particle size of 1 ⁇ m or less, in addition to decreasing the flowability of the thermal spraying powder, flocculation of the thermal spraying powder is likely to occur. If the thermal spraying powder that has been flocculated is mixed in the thermal spray coating, uniformity and density of the thermal spray coating may be decreased, through holes may be formed in the thermal spray coating, or the surface roughness of the thermal spray coating may be increased.
  • the ratio of the total volume of particles having a particle size of 1 ⁇ m or less to the total volume of all particles in the thermal spraying powder is greater than 2% (that is, when 2% particle size D 2 of the thermal spraying powder is less than 1 ⁇ m)
  • the flowability of the thermal spraying powder is significantly decreased since particles having a particle size of 1 ⁇ m or less is included in the thermal spraying powder by a large amount.
  • supply of the thermal spraying powder from the powder feeder to the spray gun during spraying becomes unstable.
  • flocculation of the thermal spraying powder may occur, thereby decreasing the uniformity and the density of the thermal spray coating, generating through holes in the thermal spray coating, or increasing the surface roughness of the thermal spray coating.
  • the granulated and sintered powder generally has sufficient flowability and less risk of contamination by impurities during a manufacturing process as compared to a fused and crushed powder and a sintered and crushed powder. Therefore, the thermal spraying powder of this embodiment consisting of the granulated and sintered powder has the same advantages.
  • the evaluation results are shown in the column entitled "Surface roughness of thermal spray coating before polishing” in table 1.
  • the thermal spraying powders were evaluated according to a three rank scale: excellent (1), good (2), and poor (3). That is, when the standard deviation of the surface roughness Ra was less than 0.3, the thermal spraying powder was ranked excellent, when it was 0.3 or more and less than 0.45, the thermal spraying powder was ranked good, and when it was 0.45 or more, the thermal spraying powder was ranked poor.
  • the evaluation results are shown in the column entitled "Variation of surface roughness" in Table 1.
  • Powder feeder "AM-30” manufactured by Technoserve Co. Ltd.
  • Oxygen flow rate 1900 scfh Kerosene flow rate: 5.1 gph Spraying distance: 250 mm
  • Base material SS400 steel plate (7 cm x 5 cm x 2.3 mm, degreased and surface roughened using an alumina grit #40)
  • Spray gun "JP-5000" manufactured by Praxair/TAFA
  • Powder feeder "AM-30” manufactured by Technoserve Co. Ltd.
  • Oxygen flow rate 1900 scfh Kerosene flow rate: 5.1 gph Spraying distance: 380 mm Barrel length: 101.6 mm
  • Table 3 Surface roughness measuring instrument: "SURFCOM 1400D-12" manufactured by TOKYO SEIMITSU CO. LTD. Measuring length: 10.0 mm Cutoff wavelength: 0.8 mm Measuring speed: 0.30 mm/second Tip: r 5 ⁇ m
