Railway track switch repair
Product Description:
Repair name: high-speed sliding bed platen
Material name: ZG230-450
Basic situation:
The high-speed turnout slide bed is frequently subjected to pressure and friction during long-term use. The traditional composite plating process is seriously polluted, and the bonding force between the coating and the base of the platen is poor, which easily causes the coating to peel off.
Repair requirements:
1. Corrosion resistance:
The protection level after 200 hours of neutral salt spray (NSS) test is not lower than the level 9 in GB/T 10125-2012.
2. Wear resistance:
The Rockwell hardness of the cladding should be HRC≥40, (hard chromium plating micro-Vickers hardness requirement≥HV800).
3. Strength of bonding layer:
According to the requirements of GB/T 8165-2008, the shear strength is ≥210MPa; the inner and outer bending tests should ensure that when the bending angle reaches 90°, the bonding layer and the coating have no visible cracks.
