Definitions

  • This invention relates to a method of surface treatment of a member of heat-resistant alloy for use in turbines, blowers, boilers or the like to render it- resistant to high temperature oxidation as well as to high temperature corrosion.
  • the present invention is directed to providing a method which overcomes the deficiences of the previous methods. Accordingly, in order to provide a member of heat-resistant alloy with high temperature oxidation resistance and high temperature corrosion resistance, the present invention provides a surface treatment method which is characterized by the steps of coating by spraying onto the surface of said member in the form of a substrate, a heat-resistant material of metals such as Ni and Cr or Ni-Cr alloys or their compounds as a first layer, then applying, as a second layer, a liquid coating containing metals such as AL, Si, Vr, Ts and the like or their alloys or compounds as the corrosion-resistant material by means of spray-coating, brush-coating or the like, and heat-treating the coated surface.
  • a surface treatment method which is characterized by the steps of coating by spraying onto the surface of said member in the form of a substrate, a heat-resistant material of metals such as Ni and Cr or Ni-Cr alloys or their compounds as a first layer, then applying, as a
  • the surface treatment method of the present invention provides the characterizing features as illustrated in Table 1 in comparison with the conventional methods.
  • a substrate of Udimet 520 (by weight 19% Cr, 12% Co, 6% Mo, 3% Ti, 2% Al, 1% Fe, Ni-Bal), widely used as an ultra-alloy for the hot parts of a gas turbine, was treated in the following sequence:
  • step (4) could be carried out using a mixture of fine. Al particles with Al 2 O 3 powder in a mixing ratio by weight of 80/20 or 50/50 or a mixture of Al with Si0 2 in a mixing ratio by weight of 80/20 or 50/50. Also step (6) could be carried out using a vacuum furnace in place of the hydrogen furnace.
  • Udimet 520 has been treated by the method of the invention by way of example, similar excellent results can also be obtained when treating the surfaces of other substrates such Ni-based alloy, Co-based alloy and stainless steel.
  • the coated surface of the substrate provided by the above described method had an extremely smooth and flat surface and Al and Si from the second layer sufficiently penetrated by diffusion into the first layer, thereby completely eliminating the fine pores of the first layer. Hence, the composite coating was. rendered wholly homogeneous.
  • Table 2 illustrates the results of fly-ash errosion resistance test, corrosion resistance test, and practical application test using gas turbine blades, each test being applied to a member treated by a method in accordance with the present invention and a member treated by a conventional method.
  • the composite coating produced by the method in accordance with the present invention had a better performance in comparison with that produced by the conventional method in the fly-ash errosion resistance test and the corrosion resistance test.
  • the coated blade produced using the method of the present invention exhibited the tendency that the deposition amount of the fuel ash became smaller.
  • a thermal inpact test comprising holding the testpiece at 1,100°C, for 15 minutes, then charging it into the water at 20°C. and repeating these procedures five times, the composite coating produced by the method of the present invention did not suffer peeling or cracking and had extremely good adhesion.
