Applying thermal spraying to machine components helps prevent chemical attack and improves the durability of equipment.

Examples and applications where this matters:

1. Protection against acidic environments:
Application: components exposed to acidic environments, for example in the chemical industry.
Example: thermally sprayed corrosion-resistant coatings, such as stainless steel or nickel-based alloys, on pumps, pipework and valves to prevent chemical attack.

2. Resistance to saltwater corrosion in marine applications:
Application: components in marine environments exposed to salt water.
Example: thermally sprayed zinc or aluminium coatings on ship components to protect against saltwater corrosion.

3. Chemically resistant coatings for aggressive substances:
Application: equipment in the chemical processing industry.
Example: applying chemically resistant coatings, such as polyamide or ceramic materials, to surfaces in contact with aggressive chemicals.

4. Protecting ventilation systems in chemical plants:
Application: ventilation systems exposed to chemical vapours.
Example: coatings resistant to corrosive gases sprayed onto fan blades and ducting to prevent chemical attack.

5. Resistance to acid rain in outdoor applications:
Application: machine components exposed to acid rain.
Example: thermally sprayed protective coatings on outdoor components, such as bridge parts, to reduce damage from acid rain.

6. Resistance to aggressive fluids in process installations:
Application: components in plants handling aggressive fluids.
Example: applying chemically resistant coatings to valves, pipes and tanks in process installations to prevent corrosion caused by chemicals.

Thermal spraying makes it possible to apply tailored coatings designed specifically to improve the chemical resistance of machine components. It is an effective way to extend equipment service life, reduce maintenance costs and safeguard the reliability of industrial machinery.
