NORD Drivesystems nsd tupH corrosion protection for aluminium drives

NORD Drivesystems manufactures permanently corrosion-resistant drives using the nsd tupH sealed surface conversion system. Aluminium drives are given a smooth, ultrahard surface that is unaffected by blows or scratches. The drives are tested in applications with a maritime atmosphere. They are also tested for resilience against blistering per ASTM D714, corrosion per ASTM D610-08 and scribe per ASTM D1654-08 according to DIN EN ISO 2409.

Additionally, the ASTM D3170 Gravelometer test showed no loss of adhesion or chipping and the ASTM B117-09 salt spray test according to DIN EN ISO 9227 produced no corrosion after 2000 h.

nsd tupH is FDA approved for food applications and treated systems resist cleaning agents in the pH2 to pH12 range. The system is available for all aluminium-enclosed drives, including four gearbox families, smooth-surface motors and distributed drive electronics units.
