“…2), multiplied by the wear track length. The second method comprises a thesis adopted by Sinha et al [42] that the worn material is actually the material detached from the bulk material, so in the second method the volume loss was calculated from the difference of cross-sectional area of displaced material and cross-sectional area of formed ridges (A D -A R , Fig. 2), multiplied by the wear track length.…”

Abrasion wear resistance is very important in many applications and it is not a surprise that there are many laboratory test methods for its determination. In this article, a possibility of the abrasive wear resistance determination with scratch tester, as a relatively easy and quick test method, was analysed and compared with the standard test method for pin abrasion testing (ASTM G 132). Materials used in the tests were: two ferrous-based coatings (deposited on an Al-Si alloy substrate with atmospheric plasma spraying), two aluminium-based composite materials with 10 wt% of Al 2 O 3 reinforcements (produced with compocasting technique) and grey cast iron, known as a material with good abrasive wear resistance. Coefficient of friction and wear of the samples were investigated with both abrasion wear test methods and analysed in correlation with their mechanical properties.

“…Inspiration can be gained from other research areas, and only a few examples will be given here. Models for mechanical degradation (abrasive wear) of polymers are developed in the field of mechanical engineering and material sciences, e.g., (Sinha et al 2007;Abdelbary 2014). Models for decomposition of biodegradable polymers are studied in the context of medical applications, like drug delivery or implantable devices, e.g., (Vieira et al 2014).…”

The use of nanomaterials in food-contact applications has created enormous interest in recent years. The potential migration of engineered nano-objects (ENOs) from food-contact materials (FCMs) is one of the most important concerns regarding potential human exposure to ENOs and health risks. Current research focusing on FCMs has often reached inconsistency regarding migration of ENOs. The scope of this critical review is to give a concise overview of the most relevant aspects of the subject, and to identify and discuss the major open questions in relation to migration of ENOs from FCMs. This includes the very fundamental questions whether ENOs can migrate from FCMs at all and what the potential release mechanisms of ENOs could be. The inconsistency of findings from experimental studies is highlighted based on the example of silver nanoparticle migration from polymer-based FCMs. Challenges in the detection and characterisation of ENOs in migration studies and the suitability of the most frequently used analytical techniques are discussed. Further, this review questions the suitability of standard food simulants and migration test conditions for FCMs as well as of conventional mathematical migration models. Considerations regarding the risk for consumers associated with migrating ENOs from FCMs are discussed. ARTICLE HISTORY

“…Two processes impact wear of polymers: cohesive wear (mainly abrasion) and interfacial wear (especially adhesion) [9,10]. The proportions of adhesion and abrasion in total wear are strongly influenced by the roughness of the metal contacting interface [11][12][13]. In polymers for SMF, mainly abrasion processes are responsible for friction and wear.…”

Advanced polymers offer at the present time concrete possibilities in reducing the product development time and production of prototypes and small series of sheet metal parts. However, the applicability of such materials requires different approaches in comparison to conventional materials for sheet metal forming dies. This paper presents investigation results dealing with tribological and tool design aspects for the use of polymeric materials in sheet metal forming. Friction and wear of sheets with different surface topologies have been investigated. A new test method for measuring polymer/sheet wear is presented. A coupled simulation model for the production of a test geometry aimed specifically at the investigation of die deformations and loads is presented. The behaviour of two polymeric materials by forming the test geometry has been simulated and the maximal loads and deformations during the process have been quantified. Simulation results have been subsequently validated in experimental testing.
