Laser Cladding of Cobalt-Based Wear-Resistant Traction Coatings on Ductile Iron Grooves of High-Speed Elevator Traction Sheaves
In the elevator industry, the traction sheave is the core power-transmission component and is subjected to continuous steel-wire-rope friction, impact loads, and complex environmental influences. Traditional ductile-iron traction sheave grooves often face insufficient wear resistance: the groove surface tends to develop uneven wear, reducing elevator ride smoothness and potentially causing wire-rope slippage and safety risks. In addition, casting-related defects such as inclusions and porosity can further accelerate wear, shorten equipment lifespan, and compromise operational safety.
To solve these challenges, it is critical to apply an advanced surface-engineering technology capable of forming a high-hardness, wear-resistant coating with strong metallurgical bonding on traction sheave grooves. This enhanced traction layer significantly improves durability, ensures stable transmission performance, and strengthens the overall reliability and safety of high-speed elevator systems.
