Increased safety and stability for rail traffic. Thermission surface coatings for the rail industry offer maximum corrosion and wear protection, even in extreme deployment conditions.

In the last 25 years more intensive transport of goods; heavier rolling stock; increased abrasion due to high-speed trains and denser traffic in urban conurbations have resulted in systematically higher loads and wear and tear on rail networks. Parallel to this, little investment has been made in the upkeep of many rail networks. Solutions are thus required to extend infrastructure service life and to limit increased financial demands.

Lower service life cycle costs

The zinc thermal diffusion process extends the service life; performance and reliability of critical components many times over, thus consistently reducing maintenance and service costs. Manufacturing costs are minimized thanks to improved weldability and optimized surface adhesion for top layers, paints and varnishes. In addition to this, the process allows light metal materials to be combined, making the separators which were previously required to prevent contact corrosion no longer necessary.

Thermission technology is suitable for rail and locomotive system fasteners and connectors; wheels and wheel sets; points; level crossings; on-board and track-side guidance systems and signalling technology.

Increased surface protection

Thermission coatings also guarantee high corrosion and wear protection and thus maximum safety and stability for rail systems – even under extreme environmental conditions:

  • At extremely cold temperatures of minus 30°C or less,
  • At high temperatures of 40°C or more, causing rails to expand,
  • In the high humidity present in railway tunnels or
  • In the salt spray encountered along coastal routes.
