Title:
WEAR-RESISTANT COATING AND METHOD FOR APPLYING IT
Document Type and Number:
WIPO Patent Application WO/2002/068716
Kind Code:
A1
Abstract:
A wear-resistant coating layer excellent in oxidation resistance and durability and applicable readily at low cost. The wear-resistant coating is formed on the end of the metal base constituting a blade of a gas turbine. The thickness of the wear-resistant coating on the end is 300 $g(m)m. Hard particles H made of CBN are fixed in a bond coating formed by heating/fusing/solidifying the mixture of a brazing filler metal and an alloy M-Cr-Al-Y (M is a metal element such as Co or Ni) on the end. The hard particles H are coated with Ni and Co so as to improve the wettability with the brazing filler metal. A part of the hard particles H are exposed from the surface of the bond coating so as to exhibit its grinding ability.
