METHOD FOR MANUFACTURING AN ABRASIVE COATING ON A GAS TURBINE COMPONENT

摘要

The invention relates to a method for manufacturing an abrasive coating o n a gas turbine component, especially on a gas turbine rotor blade tip, comp rising at least the following steps: a) providing a gas turbine component, e specially a gas turbine rotor blade; b) providing a high temperature melting alloy powder; c) providing abrasive particles; d) providing a low temperatu re melting alloy powder; e) blending at least said high temperature melting alloy powder and said abrasive particles to provide a mixture; f) applying s aid low temperature melting alloy powder and said mixture to an area of said gas turbine component, especially to a tip of said turbine rotor blade; g) locally heating said area of said gas turbine component to a temperature abo ve the melting point of said low temperature melting alloy powder but below the melting point of said high temperature melting alloy powder.
