Description

Strength of thin film coatings

Format

A data frame with 30 observations on the following 3 variables.

material

a factor with levels foil glass

comp

a numeric vector

maxload

a numeric vector

Details

“Thin films”, a coating cured on some substrate other than the actual product, are used by researchers in development. Glass and foil are two substrates that are often used. This study was used to study the impact of a component of the coating on the strength of the coating. The researcher also wanted to know if the substrate used to cure the thin film had an impact on the results.
