Molybdenum disulfide (MoS₂) is applied as a solid lubricant coating using several techniques, depending on the substrate, operating environment, and desired performance. Common application methods include:
- Burnishing: Rubbing MoS₂ powder directly into the surface, typically for dry, low-load applications.
- Spray Coating: Applying MoS₂ in a binder or solvent-based suspension that dries into a uniform dry film layer.
- Chemical Vapor Deposition (CVD): A high-temperature process that deposits crystalline MoS₂ onto the surface, creating a durable, thin film for demanding environments.
These coatings are popular in aerospace, vacuum systems, precision bearings, and sliding components, where low friction, lubricity under vacuum, or resistance to wear without oil is essential. The right application method is chosen based on part geometry, load conditions, and temperature exposure.
