Abstract

Provided are spraying powder that can suppress a decrease in the machinability of the resulting sprayed coating even under a high-temperature environment, and a method for depositing a sprayed coating using the same. The spraying powder is spraying powder for depositing a sprayed coating with an abradable property. The spraying powder includes NiCr-based alloy particles and h-BN particles. A NiCr-based alloy of the NiCr-based alloy particles contains 2 to 10 mass % of Si, and the content of the h-BN particles in the spraying powder is 4 to 8 mass %.

Claims (6)

1. A spraying powder for depositing a sprayed coating, comprising:

NiCr-based alloy particles and h-BN particles, wherein

a NiCr-based alloy of the NiCr-based alloy particles contains 2 to 10 mass % of Si,

a content of the h-BN particles in the spraying powder is 4 to 8 mass %,

the NiCr-based alloy particles consist of Ni, Cr, and Si, and

a melting point of the NiCr-based alloy particles is 940 to 1200 degrees C.
