Fretting Corrosion to Railway Axle/Armature ...

Key Benefits:

1. Shaft need not be removed from the windings

2. No pre or post grinding required

3. Hard face to prevent further damage

Capabilities:

Excessive pitting was evident caused by fretting corrosion rendering this axle unusable. The Dalic process was not only able to fill all the pits but bring the wheel back to tolerance without removal of any substrate material.  

Capability 1: Molecular Bond to Substrate  

Capability 2: Nil removal of substrate material  

Capability 3: Pits up to 0.020" filled with nickel

DALIC and Railways?

For production and maintenance, the selectivity of DALIC electroplating has definite advantages for the Railway sector. On wheel axles, journals, bearings, cannon boxes or U-tubes, electrical and diesel engines. Maintenance can be performed within your workshops by your own technicians having been trained and supplied with the needed equiptment by DALIC or by our own team of experienced technicians.

What applications with DALIC?

In the railways sector, wheelsets, engines are facing wear, fretting and fatigue damages for which DALIC can offer experienced technical solutions:

• Corrosion protection on steel with : Nickel, Zinc-Nickel, Tin-Indium, Cadmium, etc...
• Corrosion and abrasion protection on aluminium with : Anodic oxydizing
• Anti-Fretting with : Highly ductile Nickel Dalinickle Plus
• Resizing after wear with : Nickel
• Electrical Conductivity with : Tin, Silver
• Anti-friction or babbitt : Lead or ternary alloys like Nickel-Lead Tin
• They rely upon DALIC
• The greatest networks and manufactured have been evaluating the DALIC technology and among them : SNCF, Deutsche Bahn, FS, South African Railways, Indian Railways, RATP, Chemins de Fer de Russie, ALSTOM,...

Your Quality Insurance by DALIC

Quality insurance of DALIC is certified ISO 9001 by Lloyds Lrqa : agreement n° 943.379
The DALIC technology has been approved for resizing of wheelsets journals by SNCF, CFFR, AAR, IR, SAR,...

Remember, millions of km in service !
DALIC technology on wheel axles as accumulated more than 70 millions of kilometers experience on heavy trains and on high speed trains.
