MoST nano-amorphous self-lubricating coating
Introduction
MoST is a nano-amorphous coating composed of Mo element as the main component and mixed with related metal elements in a magnetron sputtering system. High hardness, ultra-low coefficient of friction, and high film/substrate bond strength.
Performance parameter table
| Category | Parameter | Remark |
Hardness | 1000HV~2000 HV | Excellent recovery flexibility |
thickness | 0.5~2.0 µm | |
friction coefficient | µ = 0.045 | under 100 N load. The higher the load, the lower the coefficient of friction |
Wear rate | 4.0 x 10-17 m3/Nm | |
Carrying capacity | 4 Gpa |
