I am in the process of designing an experiment, process and device to do further lubricity evaluations on these products. The first evaluation was for the coefficient of “static” friction but I fear it was lacking (even though it was a reasonable side by side evaluation) so Im working on evaluating “dynamic” friction forces. The long holiday weekend should provide me with time to get this going.
Static coefficient of friction was pretty straight forward with the weighted sled and the addition of water to eventually break free the friction forces between the two metal plates but I am devising a constant motion evaluation so I can capture the friction forces between two metal plates that are continually moving to gauge lubricity of the products as well as wear over a great duration than the static friction evaluation.
