Friction Test Data

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

SampleAvg. Static Coef of FrictionAvg. Kinetic Coef of Friction
Steel0.330.33
Nye-Kote™0.360.33
Nye-Tef™0.150.13
Nye-Carb™0.280.22
Kanigen®0.360.33
Hard Chrome0.390.32

Sample Identification

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