Gas dynamic cold spray, GDCS
Plakart produces Cold Gas Dynamic Spray Coatings for industrial equipment (see photo - anticorrosion Cold Gas Dynamic Spray Coating of the heat exchanger without dismantling). Besides, we deliver installations of turnkey cold gasdynamic spraying (adjustment, service, training).
In difference from other gas-thermal technologies in gasdynamic installations the firm unfused powder particles of metal dispersed to high speed interact with a firm substrate (detail). Acceleration of particles is made by a supersonic air flow.
Cold Gas Dynamic Spray Coatings advantages:

Cold Gas Dynamic Spray Coatings advantages:
- coating does not demand special conditions (cameras), is carried out on air, at any temperature and humidity;
- insignificant thermoimpact on a part surface (coating zone does not heat up higher than 100-150 degrees C). There is no deformation, oxidation, the internal tension of material;
- Cold Gas Dynamic Spray is safe for the environment (there are no high temperatures, dangerous gases, hazardous waste demanding special utilization);
- cleaning of a surface during Cold Gas Dynamic Spraying;
- the narrowly targeted stream of particles allows to apply coatings on local sites;
- mobile, easy-to-work equipment;
- it is also possible to carry out sand blasting by Cold Gas Dynamic Spray installation .
