  - TRIBOLOGY LETTERS - Year 2012

  Tribological performance of surface coatings with embedded PTFE reservoirs in rolling/sliding contact is reported. Using two different coating materials and two shapes and patterns of PTFE reservoirs test samples in the form of discs were prepared and tested in a four-ball contact configuration under loads corresponding to nominal contact pressure of 0.5 and 1.0 GPa. It was found that one coating, namely aluminium-bronze with embedded...

  W pracy przedstawiono zastosowanie nowej metody SCGC i odpowiedniego programu komputerowego JKC do oceny pomierzonej mikrostereometrii powierzchni części maszyn, głównie na potrzeby kontroli jakości. Na przykładzie powierzchni nagniatanych wykazano cechy nowej metody: wizualizację ułatwiającą wyobrażenie pomierzonej sfery chropowatości, położenie w niej najważniejszych parametrów oceny (rozkład geometrycznej powierzchni kontaktu,...

  - Solid State Phenomena - Year 2015

  The surface of the finishing machined parts is defined mainly by roughness parameters. Growing demands on the part, especially mating sliding or rolling, require the specification of additional parameters, such as waviness parameters, particularly when there is significant resistance to seizing or noise reduction. This paper presents surface waviness characteristics of hardened burnished steel.

• Microstructure and residual stresses in surface coatings with PTFE reservoirs

  Publication

  - TRIBOLOGY LETTERS - Year 2013

  The paper presents the results of experimental study into the microstructure and changes in residual stresses resulting from sliding and rolling/sliding loaded interaction between metallic surface coatings with embedded PTFE reservoirs and various counter faces. It was found that before testing surface coatings had compressive residual stresses. Molybdenum coating with all types of PTFE reservoirs displayed, as a result of testing,...

  - Solid State Phenomena - Year 2013

  Commonly used as a finishing operation, lapping has been used for achieving ultra-high finishes and close tolerances between mating pieces. Its carried out by applying loose abrasive grains between work and lap surfaces, and causing a relative motion between them resulting in a finish of multi-directional lay. The grains activity (sliding and rolling) in the working gap causes not only the material removal but also the temperature...
