“…3. Different types of steel abrasive wear rate values for different temperatures [20] Similar results can be found in other researches. As it described in [6], even a one cycle heating to 850 °C and cooling to the room temperature leads to a decrease of the fatigue strength.…”

“…This is confirmed by many experimental studies in the field of materials science. Results of such experiments described in [19][20][21] are similar: with an increase of the contact temperature, the mass loss of all the tested steels also increases. However, some types of steels are able to form a tribological layer in an abrasive medium, which increases wear resistance, even at high temperatures (Fig.…”

Mining is widely associated with the use of a variety of mining machines for various duties, such as extraction, loading and transportation of rock. Due to prolonged use of machines, the amount of wear of operating tools and machine parts increases. This problem is especially acute for mining and loading machines used in excavation and reclamation, because the wear rate is increased on those duties. The development of wear process and evaluation of the residual life of operating tools of mining and loading machines is well studied in world practice. However, given the variety of climatic, geological and mining conditions, unique for each mineral deposit, we are facing difficulties in creating a comprehensive model of wear process development. In modern researches on this area such issues as estimation of operating tools residual life during intense wear under extreme conditions of high temperatures and sharp temperature drop are understudied. These conditions are typical for deposits of such minerals as coal and peat, which are especially prone to spontaneous combustion. This review discusses methods for assessing various wear mechanisms and the effect of temperature on the intensity of those processes, as well as methods to determine the residual life of operating tools of mining and loading machines working in high-temperature environment.

In injection molding wear of components is pronounced in positions with high flow rates of melt. The platelet‐wear‐test is an established method for comparative assessment of wear resistance of tool materials in such regimes. Within this study three metal matrix composites: two hard metals and one powder metallurgical steel were investigated. Results show non‐linear wear rates with increasing amount of plastic melt processed. The reasons were found in the viscous dissipation, which is based on high volumetric flow rates and the small wear gap, leading to a temperature rise, which are detrimental especially for the PM‐steel. Analysis of the processed glass fiber‐filled polymer showed dramatic decrease of fiber length due to the processing through the wear gap. This entails a high amount of free fiber ends, resulting in higher load for the surfaces through micro chipping. POLYM. ENG. SCI., 59:E302–E311, 2019. © 2018 The Authors.
