Abstract

PURPOSE:To enhance the thermal impact and corrosion resistances of n Ni- or Co- base heat resistant alloy by coating Ti and/or Zr, Ni and Al onto the alloy surface and heating the coated alloy to form an intermetallic cpd. such as Ni(Al.Ti) or Ni(Al.Zr). CONSTITUTION:Ti and/or Zr, Ni and Al are coated onto the surface of a Ni- or Co-base heat resistant alloy by sputtering or vacuum deposition. The resulting coated layer is then heat treated to form an intermetallic cpd. such as Ni(Al.Ti), Ni(Al.Zr), Ni(AlTi.Zr), Ni3(Al.Ti), Ni3(Al.Zr) or Ni3(Al.Ti.Zr). The amt. of Al in NiAl or Ni3Alreplaced by Ti and/or Zr is pref. adjusted to about 5-70%. This method is esp. applied to parts such as a gas turbine and a jet engine which are exposed to hot corrosive gas.
