Title:
ABRASION RESISTANT COATING AND APPLICATION METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3801452
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an abrasion resistant coating superior in oxidation resistance and durability, which can be applied easily at low cost.
SOLUTION: The abrasion resistant coating is formed on a head 1a of a base material 1 which composes a blade of a gas-turbine. The abrasion resistant coating 2 on the head 1a has a thickness of 300 micrometers. On the head 1a, hard particles H consisting of CBN are stuck in a bond coating 2a, which is formed by means of melting a mixture of a soldering material and MCrAlY (M is a metal element such as Co and Ni) with heat and solidifying it. The hard particles H are coated with Ni and Co coating NC in order to improve the superior wettability against the soldering material, and parts of the hard particles H are arranged to protrude from the surface of the bond coating 2a in order to develop abrasive property.
