Abstract:
Scratch test - a measure of the quality of tribological and protective coatings of various types (tribological and protective) is widely used in industry today. It is expected that in the coming years the use of coatings will increase, especially the application of new coatings on new materials, polymers. The group of materials duromiers are hard and brittle than plastomers and can withstand higher operating temperatures. Unsaturated polyester - UP was chosen, which has good mechanical, chemical, electrical insulation properties. Especially when reinforced with glass or other fibers. This material can be modified with various coatings and colors. Examples of the results of measuring the tribological characteristics of coatings achieved by measuring the aforementioned materials with the scratch test are shown in original diagrams.
