Coefficient of Friction Test Results

This report presents the results of coefficient of friction test conducted on samples of steel coated with Nye-Kote™, Nye-Tef™, Nye-Carb™, Kanigen® and Industrial Hard Chrome. The testing data analysis was complated on January 28, 2008.

 

SUMMARY OF RESULTS:

Sample Avg. Static Coef of Friction Avg. Kinetic Coef of Friction
Steel 0.33 0.33
Nye-Kote™ 0.36 0.33
Nye-Tef™ 0.15 0.13
Nye-Carb™ 0.28 0.22
Kanigen® 0.36 0.33
Hard Chrome 0.39 0.32
Sample Identification:

The samples were identified by their coating indication; Steel, Nye-Kote™, Nye-Tef™, Nye-Carb™, Kanigen®, Hard Chrome.

Test Method:

The samples were allowed to condition at standard laboratory conditions of 72 +/- 4F and 50% +/-5% relative huimidity for at least 40 hours prior to testing. Testing was done with according to ASTM D1894. Standards used are detailed below.
