Metal and Thermal Spraying Services

Lenoch Engineering offers high-quality metal and thermal spraying services for increased durability of parts and components.

Working to optimise all types of critical componentry, the experienced engineers at Lenoch Engineering can ensure parts have increased wear resistance, corrosion resistance, and additional protection whilst performing in high-pressure environments.

Metal spraying not only increases the durability of components, but does so at a time-considerate rate, enabling Lenoch Engineering to respond quickly to enquiries, and deliver an enhanced part which meets all the unique requirements of the project.

During this process, Lenoch Engineering provides total customer transparency, ensuring we work with our clients throughout, and uphold our reputation as reliable solution providers.

Lenoch Engineering offers a full spraying operation, re-grinding to original sizes to ensure parts can be seamlessly installed back into existing systems. We do this in conjunction with our comprehensive engineering services, working alongside our clients from initial inspections to delivery.

    This service can be provided nationwide, with Lenoch Engineering working with clients around the globe. We offer UK delivery, typically within 24 hours, for the most responsive and efficient service.


    What is metal spraying?

    Metal spraying is the process of depositing molten metal onto a surface through numerous techniques. This is also referred to as thermal spraying. The molten metal particles provide a hard, even coat on the product’s surface, hardening quickly when they make contact with the surface.

    What are the methods of metal spraying?

    Metal spraying can be achieved through:


    • Flame coating - gas fuel and oxygen create a flame which is used to melt the metallic material, which is then sprayed onto a surface by compressed air through a nozzle. 
    • Arc coating - two electrically charged wires are put together within a pistol, creating an electric spark which melts the wire. This is then distributed by compressed air through a nozzle.
    • Plasma coating - a plasma gun disperses powder particles within a plasma jet to coat a surface. The plasma is created by an electrode within the nozzle which produces an electric spark.
    • HVOF (high velocity oxygen fuel) coating - a liquid or gas fuel is combined with oxygen, before being ignited. The high temperature and pressure created during this is released through a nozzle, to which powder particles are added to be coated to a surface.
    • Laser cladding - a laser beam creates a weld pool to which metallic particles are added; this mixture is then dispersed by inert shielding gas onto a surface.

    What are the advantages of metal spraying?

    Metal spraying increases hardness of a material; durability and resistance to wear, corrosion and water; alongside modifying the electrical properties of a part.
