PVD Coatings > Medikote™
Medikote™ is a family of proprietary PVD coating process specifically designed to meet the stringent quality requirements of the medical component industry.  Medikote™ PVD deposits high quality thin-film coatings with excellent micro-hardness, lubricity and adhesion characteristics. 

In addition, special emphasis is placed on:

  • Traceability
  • Inspection / Certification
  • Continuous Improvement
  • Frozen Process Control
  • Critical Process Validation
  • Service and Delivery
Since consistency of quality is a principal factor in our processes, we are pleased to be the first PVD coating facility in North America to have achieved ISO 13485: 2003 certification. This effort was premised on our policy of exceeding our customers' expectations and requirements.

Medikote™ PVD coatings improve medical devices by providing:

Biocompatibility
  1. MEM Elution Cytotoxicity Test:  Grade 0, non-toxic
  2. Non-mutagenic, non-hemolytic, non-pyrogenic
Reduced Friction
  1. Lowered Coefficient of Friction:  0.35 vs. 0.7 for uncoated steel
  2. Can prevent seizure of parts where lubrication cannot be used
Improved Wear Resistance
  1. Retention of sharp cutting edges
  2. Prevents material erosion in high wear areas
Barrier Layer
  1. Creates a chemically inert barrier (ex. Protects against Ni sensitivity)
  2. Di-electric barrier layer (Medikote™ C11 DLC only)
Improved Corrosion Resistance
  1. Helps to resist autoclave induced corrosion
  2. Improves corrosion resistance of stainless steel
Aesthetic Considerations
  1.  Identification purposes
  2. Create a distinctive look within the marketplace
In addition to our PVD coating department, our on-site engineering staff, machine shop and thin-film analysis/metallurgical laboratory allow us to achieve an unparalleled level of production efficiency.  With these resources at one location, we can design and implement custom PVD coating solutions with great efficiency and speed.
