The chosen investigations of the adhesion force of thin, superhard cotings to the cutting edges made of cemented carbides are presented in the paper. For identification of the adhesion force of coatings to the substrate an automatic scratch tester constructed at Poznań University of Technology was applied. The estimation of the adhesion force (value of critical load measured during scratch test) was...
Polymers and lightweight composites rapidly replace metals in high-tech engineering applications in automotive, aerospace, shipbuilding, civil and other engineering applications. Due to chemical inertness, hydrophobicity, surface contamination and migrating functional and processing additives, most polymers require surface modification to ascertain high strength and reliability of bonded products...
The ability to control interactions between polymeric substrate and single molecules including successful placement of molecules in desired location at technologically useful conformation and spatial architecture provides a platform for designing functional surfaces for high-tech engineered products and smart devices. Subsequent ability to control interactions between arrays of immobilized molecules...
The paper presents the evaluation of the quality and adherence of rhodium layers deposited on the nickel substrate. Rhodium layers (0.2 and 0.5 mm thick) were deposited by the electroplating method on the surface of the nickel substrate. The scratch test method (REVETEST R) was applied to determine the adhesion of layers. The increase of test force from 0.9 to 5 N and from 0.9 to 10 N did not lead...
