Thick coatings

Thermal Spraying

Process in which thermal energy is used to create a spraying of material onto a surface, in molten, semi-molten or plasticized state, to provide a coating.

EAWS – Electric Arc Wire Spraying

Metals and alloys: Cu; Co; Al; Zn; Mo; NiAl; NiCr; NiCrMo; NiCrAlY, Aços.

. Raw material: wire.
. Typical flow: 10 to 20 Kg/h.
. Typical speed of the particles: 100 m/s.
. Power supply: electric arc .
. Power supply temperature: 5500 ºC.
. Typical adhesion tensions: 15 to 40 MPa.
. Typical porosity: 3 %.
. Typical coating thickness: 200 to 5000 µm.

Objective

To adapt and improve the surfaces for the solicitations that will be submitted, providing them characteristics of:

. Resistance to wear (abrasion, erosion and friction);
. Corrosion and oxidation resistance;
. Thermal barrier;
. Óptical;
. Biocompatibility.

Advantages for the customer

. Higher components lifetime;
. Costs reduction;
. Lower maintenance and repair times;
. Higher global productivity;
. Higher product quality.
