TS 7228

TS 7228 is a terminology standard for thermal spraying, bringing together the terms and definitions used in this field. It provides a common technical language for spraying materials, spray types, thermal spraying by energy source, general terms, spray guns, and related properties. As with other terminology standards, its value lies in harmonizing concepts rather than prescribing how the process must be carried out.

The technical framework behind thermal spraying terms

Thermal spraying is a family of coating processes in which a feedstock material is heated and propelled onto a surface to form a deposit. In practice, the field includes several process families and energy sources, such as flame spraying, arc spraying, plasma spraying, and related variants. A terminology document like this helps distinguish clearly between the material being sprayed, the heat source, the spraying arrangement, the spray gun, and the properties of the resulting coating.

Conceptual areas covered by this standard

• Terms and definitions for thermal spraying according to spraying materials
• Common technical names for spray types
• Thermal spraying classifications by energy source
• General process terms and concepts related to the spray gun
• Basic definitions used to describe coating and process properties

The standard also sits within a terminology tradition associated with sources such as DIN 32530.5, AWS A3.0, and JIS Z 3001. This makes it useful for maintaining consistent language across manufacturing engineering, surface engineering, and closely related welding and fabrication contexts. In specifications, training material, and process documentation, shared terminology is essential for avoiding ambiguity and aligning technical communication.
