Method for determining the coefficient of friction variation pattern as a function of density at low temperatures using the example of dry ice–steel contact

HIGHLIGHTS

• What: The literature review conducted for this research has revealed a shortage of experimental research methods allowing a determination of the coefficient of at low temperatures approximately 200 K. This Article proposes a method for determining the coefficient of dry ice sliding against steel. In the following chapter dealing with the analysis of experimental results, the authors compare the goodness of fit of various mathematical functions used for the regression of the studied variations. The following non-linear were2.7.3, used program in the analysis: exponential ,2.7.3. geometric , sinusoidal ,functions and natural were used . . .
