Dry & Solid Film Lubricant Coating Services

Low-friction, wear-resistant dry film lubricants applied for high-reliability aerospace, defense, and industrial components requiring durable, uniform performance under load.

High-Performance Solid Film Lubricant Capabilities

Dry and solid film lubricants provide controlled friction, enhanced wear resistance, and long-term performance where traditional wet lubricants are impractical or insufficient. MIL applies these coatings with precision, ensuring compliance with complex MIL-spec and OEM requirements.

Coating Types & Capabilities

  • Molybdenum disulfide (MoS₂) dry film lubricants
  • PTFE-based solid film coatings
  • Graphite-based dry films
  • Low-friction, anti-galling finishes
  • Corrosion-inhibiting lubricant coatings
  • Controlled thickness, uniformity & adhesion

How Dry / Solid Film Lubricant Coatings Work

Step 1 — Surface Preparation

Achieving proper adhesion and friction control begins with correct substrate preparation. Depending on the spec, this may include:

  • Abrasive blasting
  • Chemical pretreatment
  • Anodize or chem film undercoats
  • Cleaning and masking for precision areas

Step 2 — Coating Application

Dry film lubricants are applied as thin, uniform layers that bond to the substrate. These coatings:

  • Reduce metal-to-metal friction
  • Limit galling and seizing
  • Extend component service life
  • Perform in extreme environments

Typical film thickness ranges from 0.0002″ to 0.001″, depending on the application.

Step 3 — Controlled Curing

Parts are cured according to the coating specification to ensure:

  • Full film hardness
  • Wear resistance
  • Chemical resistance
  • Stable, predictable coefficient of friction

Step 4 — Inspection & Quality Validation

MIL validates coating performance with:

  • Coating thickness measurement
  • Adhesion verification
  • Visual inspection
  • Gloss/appearance checks as required
  • Documentation for aerospace, defense, and medical requirements

Frequently Asked Questions About Dry & Solid Film Lubricant Coatings

A solid film lubricant is a thin, bonded coating, often MoS₂ or PTFE-based, that reduces friction and wear when conventional lubricants cannot be used.

Dry films are ideal when:

  • Parts cannot be re-lubricated during service
  • Heat or environment causes oil/grease to break down
  • Clean, contamination-free operation is required
  • Uniform low-friction properties are needed

Most coatings range from 0.0002″–0.001″, depending on the coating system and specification.

Yes. Epoxy primers, anodize, and chem film are commonly used as underlayers to enhance adhesion and corrosion resistance, MIL performs all steps in-house.

Accordion Content

Yes. MoS₂-based coatings are among the most common dry film lubricants MIL processes.
