• Positive ion bond to metal creates excellent adhesion - no chipping, flaking or peeling.
• Density of MEDCOAT 2000™ makes it more lubricious.
• Reduces friction: does not rub away or generate heat.
• Reduces galling and seizing.
• Cleaning instruments is quick and easy.
• Non-magnetic: will not affect any sensitive electronic operating room equipment.
• Wear resistance is 14 times greater than uncoated stainless steel.
• Electrical conductivity of MEDCOAT 2000™ is greater than that of stainless steel.
• Hardness of Rc 72-74: near ceramic hardness.
• Provides a barrier to nickel exposure.

Testing to the subchronic level has already been completed. MEDCOAT 2000™ is an extensively GLP tested USP class approved coating that exceeds many Tripartite Guidelines and meets many ISP 9000 biocompatibility standards pertaining to subchronic use classifications. Our medical device coating has tested favorably to some of the ISO 10993 biocompatibility standard for medical.

MEDCOAT 2000™ - Application

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 sales engineers to establish the proper coating thickness and tolerance. The practical coating range for MEDCOAT 2000™ is 0.00005" to 0.0006" (1.2µ to 15.38µ). Depending upon the thickness specified and the part's quality requirements, the following thickness tolerance can typically be maintained: ±.0001". Coating thickness is measured and can be certified, using fluorescence X-Ray technology. For thicker applications and special conditions, please consult one of our sales engineers.

MEDCOAT 2000™'s maximum operating temperature during processing will not exceed 400°F. MEDCOAT 2000™ can withstand approximately 1600° F (710° C). Oxidation begins at approximately 1100° F (430° C). Diffusion occurs at 1650° F (740° C). Time-at-temperature parameters should be reviewed with The Electrolizing Corporation of Ohio technical staff prior to specifying or testing MEDCOAT 2000™.

• Abrasion and 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.

• Surface Finish

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. It can be applied in a dull non-reflective finish, satin or bright finish.

Samples of our medical device coating 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 1000 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 of the outer surfaces of the samples.

When submitting parts for processing, clearly specify the basis metal designation, required MEDCOAT 2000™ thickness and tolerance, and 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.

For maximum protection against damage and corrosion, before 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 processing. The Electrolizing Corporation of Ohio will remove oil, grease and other preservative materials. We can provide custom packaging to customer specification, so that the product is shipped ready for sterilization and use.
