WE CAN APPLY ALL COATING TYPES
WE CAN PERFECTLY HANDLE ALL COATINGS
The skilled technicians of Bekkers repair and overhaul the most diverse range of machine components – from a minute axle to an enormous roller drum.
Thermal spraying involves the application of a metal, ceramic or synthetic layer on a surface to give it specific properties – e.g., wear resistance.
STATE OF THE ART
Bekkers is renowned for its long experience in craftsmanship – the perfect basis for the ultramodern techniques that the company now applies.
NEW SPRAYING CABINS
Our new spraying cabins will soon come into use, thereby more than doubling our capacity.
Fully automatic robots that we can set for every object.
Thermal spraying is a technique whereby a material, be it metal or ceramic or synthetic, in wire or powder form is heated by means of a thermal spray gun and sprayed on a surface. This results in a covering layer with improved properties for the function of the component.
Thermal spraying is, with only one exception, a cold process, meaning that despite the heat source of the spray gun with which the metal is melted and sprayed, the processed component will only experience a slight temperature increase from the heat transfer of the deposited droplets. No deformation, changing structure or mixing can take place at the customary spraying temperature of 50° to 200° C.
A cold sprayed layer has a lamellar structure, somewhat comparable to a cast iron structure. In case of some sprayed metal layers, micropores and oxide inclusions can lead to a low friction coefficient and extreme hardness. Also, microporous spray layers offer a high absorption of lubricants, thereby preventing wear caused by metal on metal contact.
Properties thermally sprayed layers:
- Thin (20 µm) to thick layers (7 mm)
- Surface roughness, sprayed 1-50µm Ra
- Treated: to approx. 0.01µm Ra
- Internal and external surfaces
- Nearly independent of workpiece size
