MEDCOAT 2000™
MEDCOAT is a Medical Device Coating
|
| CLASSIFICATION |
| MEDCOAT 2000 is
a precisely controlled, extremely hard and dense low-friction,
non-magnetic chromium coating. The coating is uniformly deposited
on metals using proprietary methods. Extreme lubricity and durability
are hallmarks of this process, which was developed specifically
for medical devices. MEDCOAT 2000 increases wear resistance,
reduces friction, prevents galling and seizing and minimizes
corrosion. |
|
|
| BASIS METALS |
| All grades of stainless
steel can be processed. MEDCOAT 2000™ can
also be applied to most ferrous metals, and some nonferrous metals,
such as copper and aluminum. |
| |
| OPERATING TEMPERATURE |
| The coatings
maximum operating temperature is approximately 1600° F (710° C).
Time-at-temperature parameters should be reviewed with The Electrolizing
Corporation of OHIO |
|
| APPLICATION |
Unless otherwise
specified, MEDCOAT 2000 is applied directly to the base
metal without an
intermediate coating. This medical coating is applied following completion of
all
base
metal processing, which includes a proprietary surface preparation procedure
as part
of the MEDCOAT
2000 process. This medical device coating can also be applied to existing medical
products.
Surfaces will be stripped and prepared prior to coating. A single application
of MEDCOAT 2000 will prolong the service life of the product, enhance its performance,
and maintain existing appearance. |
| |
| SURFACE QUALITY |
| Application of MEDCOAT 2000 results in a smooth,
fine-grained deposit that is uniform in thickness and appearance.
The surface is free of blisters, pits, nodules and porosity.
There is minimal edge buildup from our proprietary medical
device coating. |
| |
| THICKNESS |
| MEDCOAT 2000 can be applied with great precision
and consistency. Each part drawing should specify the coating
thickness dimension and tolerance. Consult one of our Application
Engineers to establish the proper coating thickness and tolerance.
The practical coating range for MEDCOAT 2000 is: 0.000025 to
0.0006 (0.64΅ to 15.38΅). Depending upon the thickness specified,
and the parts quality requirements, the following thickness
tolerance can be maintained: ± .00001 to ± 0.00005 ( ± 0.25΅ to ± 1.28΅).
Coating thickness is measured, and can be certified, using
state-of-the-art fluorescence X-Ray technology. For thicker
applications and special conditions, please consult one of
our Application Engineers. |
 |
ADHESION |
| Medical
devices can be repeatedly bent and twisted without MEDCOAT
2000™ chipping,
flaking or otherwise separating from the stainless steel
surface. |
| |
| HARDNESS |
| Our medical
coating significantly increases the surface layer hardness
of uncoated steel. Hardness
of the coating, as applied
to laboratory samples, is Rc72. |

a registered trademark of DuPont. |
| |
| COVERAGE & SURFACE
FINISH |
| Critical surfaces to be covered by MEDCOAT 2000,
and areas that are not to be covered, should be clearly indicated
on the part drawing. To allow most economical processing,
optional areas of the part should also be indicated. The
Roughness Average (Ra) of this medical coating, when measured
in accordance with ASME B 46.1-1995, will not significantly
vary from the Ra of the part prior to coating. Internal and
external surfaces of virtually all shapes and configurations
can be uniformly coated. Review specific requirements with
one of our application engineers. |
| |
| PROCESSING TEMPERATURE |
| During cleaning
and coating, the temperature of parts does not exceed 212° F (100° C). |
| |
| EFFECT ON BASIS METAL STRENGTH |
| Tests
of tensile and fatigue properties of our medical coating
are conducted monthly. Reports are kept on file. |
| |
| ABRASION & WEAR
RESISTANCE |
| Taber Abrasion Wear Resistance testing was conducted
on MEDCOAT 2000. Two types of stainless steel were used
in these tests: AMS 5511 (low C, 18% Cr, 8% Ni steel: Sheet;
AMS for SAE 30304) and AMS 5504 (.15% C, 12.5% Cr steel:
Sheet; AMS for SAE 51410). One of each material type was
coated with MEDCOAT 2000: one was coated with conventional
hard chrome, the other was uncoated. Testing was performed
in compliance with Specification FED-STD-141, Method 6192.1.
CS-10 Calibrase Wheels were used. One thousand grams of pressure
was used against the test panels. The panels were cleaned
with acetone prior to weighing. Results of the testing show
a great improvement in wear resistance of the MEDCOAT 2000 specimens
versus the conventional hard-chrome-plated specimen and the
uncoated specimen. |

| prior to specifying
or testing MEDCOAT 2000. Oxidation begins at approximately
1100° F (430° C). Diffusion occurs at 1650° F (740° C). |
| |
|
| |
| BIOCOMPATIBILITY |
| The MEDCOAT
2000 coating meets or exceeds USP Class VI Certification. |
| |
| AUTOCLAVABILITY |
| Samples of MEDCOAT 2000 show no evidence of discoloration,
cracking, flaking, rust or other change following repeated
autoclave exposures. Two samples, placed in a heat-resistant
dish, were subjected to over 40 autoclave cycles. Steam exposure
was conducted in production type, gravity displacement steam
sterilization vessels at 250° F (121° C). After every fifth
cycle, visual and microscopic inspections were made for discoloration
and degradation of the samples. Tests were discontinued because
repeated autoclave exposures had no effect on the outer surfaces
of the samples. |
| |
| ORDERING |
| When submitting parts for processing, clearly
specify the basis metal designation, required MEDCOAT 2000 thickness
and tolerance, and an accompanying part print that delineates
coverage: critical surfaces to be covered by MEDCOAT 2000,
areas not to be covered, and optional areas. To achieve optimum
performance and cost-effectiveness, all coating requirements
should be reviewed with The Electrolizing Corporation of
OHIO prior to processing. |
| |
| PACKING & SHIPPING |
| For maximum
protection against damage and corrosion prior to and after
processing, all parts must be properly wrapped, preserved
and shipped in suitable containers. Parts need to be free
of scale, rust and corrosion prior to coating. Prior to processing,
The Electrolizing Corporation of OHIO will remove oil, grease
and other preservative materials. We can provide custom packaging
to customer specifications, so that the product is shipped
ready for sterilization and use. |
| |
| CERTIFICATION |
| Certification
of compliance to specifications is available upon request. |

| ANODIZING
FOR ALUMINUM MEDICAL DEVICES |
| (MEDCOAT
2001™) |
| This specialized, biocompatible anodizing process
penetrates the base metal to the same degree that it builds
up on the surface of the metal. When referring to this type
of anodizing, the term thickness includes both the amount
of penetration and the amount of buildup on the surface of
the metal. For further information and extensive test data
on this proprietary anodizing process, contact The Electrolizing
Corporation of OHIO for the Technical Bulletin: Anodizing
for Aluminum Medical Devices (MEDCOAT 2001). |
| |
| ELECTROPOLISHING
FOR MEDICAL DEVICES |
| (MEDCOAT
2002™) |
| This process polishes, brightens, deburs and passivates
stainless steel, titanium and nickel titanium (nitinol).
The process leaves a unidirectional, occlusion-free and hydrogen-free
surface that helps prevent the growth of bacteria. A proprietary
process is used to electropolish titanium, nickel titanium
(nitinol) and nickel silver. For further information, contact
The Electrolizing Corporation of OHIO for the Technical Bulletin:
Electropolishing for Medical Devices (MEDCOAT 2002). |
