Abstract

Masking solutions for parts needing special treatments such as shot peening, grit blasting or thermal spray are now commonly used in industrial processes for the aerospace, industrial gas turbine, and medical industries. The ever-evolving special treatment methods require adapting the masking solutions so they retain their efficiency and quality level. This paper will describe the choices made in combining materials, geometry and surface finish of the masks to provide the necessary compliance with the thermal spraying processes or other special treatment requirements. We will demonstrate that successful masking designs are often the result of close collaboration between the operator’s engineering team and the masking solutions provider in order to comply with what is always a bespoke process. Innovations in materials and additive manufacturing enable the process towards tailored solutions which enable these industries to increase their productivity and level of manufacturing quality.
