Hard chrome replacement for Roof support Cylinder

Conventional solution: Hard chrome plating

  • Not permitted by changing health and environmental regulations globally.
  • Thin layers with thickness 0.05-0.07mm
  • Weak mechanical bonding leads to peeling off
  • Appearance of pores and cracks easily decrease the corrosion resistance
  • Service life: 1-1.5 year

New solution: laser cladding

  • Sustainable technology
  • Thicker layers:around 0.6mm
  • Strong metallurgical bonding
  • Minimise porosity which improve the corrosion resistance
  • Service life: 5-8 years
