Permanent corrosion-resistance
03 December 2014
NORD Drivesystems manufactures permanently corrosion-resistant drives using the nsd tupH sealed surface conversion system, resulting in a smooth, ultra-hard surface that, in contrast to paint, is unaffected by blows or scratches.
The drives are tested and proven in applications with a maritime atmosphere. Previous to that, they have proven their resilience against blistering per ASTM D714, corrosion per ASTM D610-08, and scribe per ASTM D1654-08 according to DIN EN ISO 2409. Additionally, ASTM D3170 Gravelometer test showed absolutely no loss of adhesion or chipping. The ASTM B117-09 salt spray test according to DIN EN ISO 9227 produced no corrosion even after 2000 hours.
In demanding atmospheres, nsd tupH drives can be used much beyond the usual service life of paint-coated systems. Their resilience and prolonged service life significantly reduces the service and maintenance requirements placed on customers.
