What
is Medikote™?
Medikote™ is a family of specialized PVD coating process
specifically designed to meet the stringent quality requirements
of the medical component industry. Medikote™ denotes a higher
level of detail at every stage: incoming inspection, part preparation,
fixturing/masking, deposition, and final inspection. Traceability,
critical process validation, frozen process control, continuous
improvement, service and delivery all stressed as part of this
process.
The PVD deposition
method used for Medikote™ includes the latest advancements
in cathodic arc deposition technology: our Electro-Magnetic Controlled
Arc Deposition (EMCAD) coating process. EMCAD utilizes a proprietary
macro-particle separation technique in order to ensure the highest
quality of coating deposition. This coating method provides low
temperature coating capability for temperature sensitive substrates,
while still maintaining very strong adhesion characteristics.
In addition, our EMCAD process will provide you with a dense,
ultra-smooth, thin-film coating superior to any other PVD coating
on the market.
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 |
|
•
Barrier Layer
1.
Creates inert barrier (ex. – protects from Ni sensitivity)
2. Dielectric barrier layer (Medikote™ C11 DLC only) |
•
Reduced friction
1. Coefficient of Friction: 0.35 vs. 0.7 for uncoated steel
2. Can prevent seizure of non-lubricated parts |
|
•
Improved Corrosion Resistance
1. Helps to resist autoclave induced corrosion
2. Improves corrosion resistance of stainless steel |
•
Improved Wear Resistance
1. Sharp cutting edge retention
2. Prevents material erosion in high wear areas |
|
•
Aesthetic Considerations
1. Identification purposes
2. Create a distinctive look within the marketplace |
