Tribaloy T-400 is a cobalt-based alloy that's highly regarded for its exceptional wear and corrosion resistance, particularly in situations where lubrication is difficult or impossible. Here's a breakdown of its key features:  

Core Characteristics:

• Composition:
  • It's primarily a cobalt alloy, with significant additions of chromium, molybdenum, and silicon.
  • This specific combination creates a unique microstructure with hard intermetallic (Laves) phases within a softer matrix.  
• Key Properties:
  • Wear Resistance:
    • T-400 is known for its ability to withstand various types of wear, including abrasive, adhesive, and erosive wear.
  • Galling Resistance:
    • It's highly effective in preventing galling, which is a form of surface damage caused by friction and adhesion.
  • Corrosion Resistance:
    • The alloy offers good resistance to corrosion, enabling its use in challenging environments.  
  • High-Temperature Stability:
    • It maintains its desirable properties at elevated temperatures, making it suitable for high-heat applications.
