Introduction

This standard defines the determination of thermal spray deposition efficiency. This standard describes the determination of thermal spray deposition efficiency require the use of the specimen; measurement Specific thermal spraying and thermal spray material deposition efficiency of the implementation process.

According to the deposition efficiency of the standard specimen calculations do not necessarily correspond with the actual efficiency of the deposition member.

Determination of thermal spraying thermal spray deposition efficiency

1 Scope

In determining the thermal spraying material needs, it is necessary to apply this standard data on spraying deposition efficiency.

This standard specifies thermal spray deposition efficiency measurement program, and the associated thermal spray materials, equipment and auxiliary materials.

This standard applies to all thermal spray processes (see ISO 14917) and all the wires, rods, and core material powder thermal spray materials.
