Introduction

Proper selection of post-treatment and/or finishing procedures for thermal spray coatings is a critical factor in ensuring the proper use of thermal spray parts. hot spray

The processing and/or treatment of coatings must particularly consider the layered structure of the coating, which is significantly different from that of castings or forgings of the same material.

Finishing techniques used on castings or forgings may damage thermal spray coatings.

Thermal Spray Post-processing and finishing of thermal spray coatings

1 Scope
