  • Y. Tsybrii
  • O. Nosko

  - WEAR - Rok 2020

  Airborne wear particles emitted from transport vehicle brakes are one of the main sources of toxic metals in inhalable particulate matter. Prediction of wear particle emissions may become more accurate if the relationship between the wear and particle emission characteristics is known. An experimental study was performed to investigate proportional correlations between the mass wear, 0.01–0.42 μm particle emission measured by a NanoScan...

• Effective density of airborne wear particles from car brake materials

  Publikacja

  • O. Nosko
  • U. Olofsson

  - JOURNAL OF AEROSOL SCIENCE - Rok 2017

  People living in urban environments are subject to high health risks due to various anthropogenic sources of airborne particulate matter, including wear of transport vehicle brakes. Studies of airborne particles often require an estimate of the effective particle density, a property that allows correct matching of mass and size characteristics measured by different aerosol instruments. In this study we investigated the effective...

• A Study on Emission of Airborne Wear Particles from Car Brake Friction Pairs

  Publikacja

  • O. Nosko
  • I. Metinoz
  • U. Olofsson

  - SAE International Journal of Materials and Manufacturing - Rok 2016

  The emission of airborne wear particles from friction material / cast iron pairs used in car brakes was investigated, paying special attention to the influence of temperature. Five low-metallic materials and one non-asbestos organic material were tested using a pin-on-disc machine. The machine was placed in a sealed chamber to allow airborne particle collection. The concentration and size distribution of 0.0056 to 10 μm particles...

• Quantification of ultrafine airborne particulate matter generated by the wear of car brake materials

  Publikacja

  • O. Nosko
  • U. Olofsson

  - WEAR - Rok 2017

  The wear of car brakes is one of the main sources of airborne particulate matter in urban environments. Ultrafine wear particles are of special environmental interest since they can easily penetrate the human body through inhalation and cause various diseases. In the present study, the contribution of ultrafine particles to airborne particulate matter emitted from car brake materials was investigated under different friction conditions....

• Airborne wear particle emission from train brake friction materials with different contents of steel and copper fibres

  Publikacja

  • Y. Tsybrii
  • I. Zglobicka
  • M. Kuciej
  • O. Nosko
  • K. Golak

  - WEAR - Rok 2022

  This study investigated the influence of the amount of steel and copper fibres in a train brake friction material on the tribological performance, emission intensity and characteristics of airborne wear particles. The particles were generated on a pin-on-disc tribometer under controlled friction and environmental conditions. It was found that the steel fibre results in a more intensive emission of 0.3–10 μm particles compared to...

• Types of wear and tear of biomaterials used in orthopaedic surgery

  Publikacja

  • L. Klimek
  • E. Wołowiec
  • B. Majkowska-Marzec

  - Journal of Achievements in Materials and Manufacturing Engineering - Rok 2013

  Purpose of this paper is presentation of observations on different kinds of wear and tear of biomaterials used in contemporary orthopaedic surgery. Types of prosthesis damage, encountered in medical practice, and their causes have been described. Results of many clinical studies were analysed to review prosthesis damage from the stage of implanting (such as intrusion of a foreign object between its components) to their natural...

• Emission and properties of airborne wear particles from train brake friction materials based on novolac phenolic resins and butadiene rubbers

  Publikacja

  • Y. Tsybrii
  • O. Nosko
  • I. Zglobicka
  • M. Kuciej

  - WEAR - Rok 2024

  The emission of airborne particulate matter from a train brake depends on the formulation of its friction material. This study investigates the emission and properties of wear particles from train brake friction materials based on straight or resorcinol-modified novolac phenolic resin and nitrile or styrene butadiene rubber used as binding ingredients. The wear particles are generated by a pin-on-disc tribomachine inside an aerodynamic...

• Where the Second World War in Europe broke out: the land-scape history of Westerplatte, Gdańsk/Danzig

  Publikacja

  • S. Kowalski
  • A. Woźniakowski
  • P. Samól

  - Land - Rok 2023

  Westerplatte is known as the place where the Second World War in Europe broke out. However, its history covers many other events involving Polish, German, Russian and even French politics over the last three centuries - neglected by many papers published in the current discussion. Due to its location at the entrance to the main harbour on the Baltic Sea entrance, Wester-platte-Peninsula is cartographically the best-documented part...

• Lubricity-based estimation of the changes in the brake fluid quality

  Publikacja

  • P. Bzura

  - Journal of KONES - Rok 2007

  W artykule przedstawiono, na podstawie wyników badań laboratoryjnych, możliwość określenia wartości smarności łączącej własności fizykochemiczne i reologiczne płynów. Smarność, która została określona dla trzech płynów hamulcowych (oznaczenia zastrzeżone przez firmę zlecającą porównanie ich własności), umożliwiła wybór najlepszego, który pewnie zostanie zastosowany w instalacjach hamulcowych samochodów.
