Wire Pulleys
The use of HVOF, HVAF to apply Tungsten Carbide and the Arc Spray process to apply 420 Stainless steel are popular choices.
The carbide coatings offer excellent protection against the sliding wear of the draw process as well as long term resistance to impact, abrasion, and other complex wear mechanisms. The material matrix is adjusted to suit the application.
Wire Drawing Capstans
Ceramics in powder, rod or Flexicord form are also a common choice for sliding wear, with Chrome Oxide being the most popular as it can be used at service temperatures up to 850°C.
