- •
The coating interface forms mechanical and certain metallurgical bonding after LR.
- •
The coating by LR is composed of WC and traces of W2C, decarbonized from WC.
- •
The average COF of WC-12Co coating under lubricated condition is only 0.052.
- •
The wear mechanism is composed of abrasive wear, cracking and fatigue spelling.
