Wear Mechanism of Al2O3/WS2 With PEEK/BG Plastic

Abstract

In the present paper, a model of wear mechanism of Al2O3/WS2 with polyether ether ketone (PEEK)/BG plastic has been presented. An amorphous Al2O3 oxide layer with a tungsten disulfide modifier has been characterized by the Scanning Electron Microscope equipped with an Energy Dispensive Spectrometer (SEM/EDS) and XRD analysis. The addition of WS2 to the acid bath reduces the friction coefficient of the Al2O3/WS2-PEEK/BG friction pair. The technology applied to receive the Al2O3/WS2 layer, with appropriately selected conditions, allows us to obtain a tribological layer that enables the delivery of WS2 solid lubricant during friction.

Safety of CMS Experiment Systems Operation – Integration of a New CO2 Fire Extinguishing Weighing System to the CMS Safety Panel

“…Such situation may be met in many industrial and research areas. In materials science, it may be a powder sintering (Dudek et al, 2010), a laser beam machining (Scendo et al, 2014;Dwornicka et al, 2017;, a wear investigation (Korzekwa et al, 2014), testing of thermal coatings (Guidoni et al, 2005), an analysis of thermal reaction (Ulewicz and Radzymińska-Lenarcik, 2011;Klimecka-Tatar et al, 2015), a corrosion limitation (Szabracki and Lipiński, 2014;Klimecka-Tatar, 2018), a bioceramic coatings creation and testing (Dudek, 2011). It may be also met in biotechnology (Skrzypczak- Pietraszek and Pietraszek, 2009;Skrzypczak-Pietraszek et al, 2018) or technical fluid mechanics (Lisowski and Filo, 2017;Fabiś-Domagała et al, 2018).…”

Tpm Safety Impact – Case Study

“…The approach, similar to the one presented in this article, can also be very useful both in other branches of industry as well as in the research area. It seems that may successfully applied in metallurgy Salek and Klimecka-Tatar, 2016), materials science (Korzekwa et al, 2014;Ulewicz and Novy, 2016;Korzekwa et al, 2018), chemistry (Ulewicz and Radzyminska-Lenarcik, 2014;Ulewicz and Radzyminska-Lenarcik, 2015), machining (Radek et al, 2017a;Radek et al, 2017b;Pietraszek et al, 2017;Radek et al, 2018), even supported by an image analysis methods (Gadek et al, 2006;Gadek-Moszczak, 2017;Gadek-Moszczak and Matusiewicz, 2017), and especially in very environment-sensitive biotechnology (Skrzypczak- Pietraszek, 2016;Skrzypczak-Pietraszek et al, 2018a;Skrzypczak-Pietraszek et al, 2018b). It would be very interesting to include a fuzzy description of the problem (Fabis-Domagala et al, 2018;Filo et al, 2018), which allows you to express uncertainty about the process.…”

Matrix FMEA Analysis of the Flow Control Valve

“…Matrix FMEA analysis may by supported by other design tools or knowledge base to define potential failures which may appear or probability of failures occurrence. The approach presented in this paper may be also useful for researchers in other area because it is strong tool (Kielbus and Karpisz, 2019) for significant quality improvement in a management (Kozien and Kozien, 2017;Maszke et al, 2018) as well as in biotechnology (Skrzypczak-Pietraszek and Pietraszek, 2012), materials science (Korzekwa et al, 2014;Lipinski, 2015), machine design (Pacana and Pacana, 2018;Karpisz and Kielbus, 2019).…”
